In addition, the terms "including" and "having" and any variations of them are intended to cover non-exclusive inclusion, for example, including a series of steps or units. The method, system, or device is not necessarily limited to those clearly listed steps or modules, but may include other steps or modules that are not clearly listed or are inherent to these processes, methods, products, or equipment.

The embodiment of the application provides a terminal device, which can be a mobile phone, a tablet computer, a notebook, a car computer, a smart watch, a smart bracelet, and other electronic products. The embodiment of the application does not specifically limit the specific form of the terminal device .

The terminal equipment of this application includes a power supply system. The use of this power supply system can avoid problems such as slow response of terminal equipment due to insufficient power supply. The following embodiments further illustrate the power supply system of the present application.

Fig. 1 is a schematic diagram of a power supply system provided by an embodiment of the application. As shown in FIG. 1, the power supply system 01 includes: a power supply module 10, a switch module 20 (also referred to as SWITCH), and a system-on-chip SOC 30. Wherein, the power supply module 10 has multiple power supply output terminals X1-X4 (this application is not limited to the four power supply output terminals X1, X2, X3, X4 in FIG. 1), and multiple power supply output terminals X1-X4 and the switch module The input terminal of the switch module 20 is connected, and the output terminals Y1 and Y2 of the switch module 20 (this application is not limited to the two output terminals Y1, Y2 in FIG. 1) are connected to the SOC 30; the switch module 20 is configured to control multiple power supply outputs The connection between terminals X1-X4 and SOC 30 respectively.

It is understandable that the power supply module 10 is provided with a power supply unit corresponding to each power supply output terminal (X1, X2, X3, X4), so as to output an electrical signal (such as a current signal) to each power supply output terminal through each power supply unit. .

In addition, it can also be understood that, as an important core device in terminal equipment, SOC is equipped with multiple load modules, such as a central processing unit (CPU) core (the following and the drawings are abbreviated as CPU_B ), small CPU core (abbreviated as CPU_L in the following and figures), middle CPU core (abbreviated as CPU_M in the following and figures), graphics processing unit (GPU), embedded neural network processor (neural-network) Processing unit, NPU) and other load modules. When an application program is run on a terminal device, some load modules in the SOC that are adapted to the application program need to be powered to meet the normal operation of the application program.

The power supply system of the present application can selectively control the on-off between one or more of the multiple power supply output terminals of the power supply module and the SOC by setting the switch module, that is, selectively control the switching of one or more power supply output terminals (That is, the output current of the power supply unit) is output to the SOC, that is, it can selectively supply power according to the power supply requirements of the load module in the SOC by adopting a single-phase or multi-phase power supply mode, so as to meet the power supply of the load module in the SOC. At the same time, there is no need to set a fixed single power supply unit and multiple power supply units (ie a fixed single-phase and multi-phase combined power supply mode) to each load module in the SOC, thereby reducing the number of power supply units and improving power supply efficiency .

The power supply module 10 and the switch module 20 in the power supply system 01 of the present application will be further described below.

As shown in Figure 2, the power supply module 10 includes a multiphase controller (multiphase controller) 100 and a multiphase BUCK circuit (also called a buck converter circuit; English name: buck converter) 101-104 (this application is not limited (In Figure 2 4- phase BUCK circuits 101, 102, 103, 104). Among them, the multi-phase controller 100 is connected to the input terminals of the multi-phase BUCK circuits 101-104, and the output terminals of the multi-phase BUCK circuits 101-104 correspond to the multiple power supply output terminals X1-X4 of the power supply module 10, that is, the multi-phase BUCK circuit. The output terminals of the circuits 101-104 serve as multiple power supply output terminals X1-X4 of the power supply module 10.

It can be understood that the above-mentioned BUCK circuit can be equivalent to the aforementioned power supply unit; and the above-mentioned multi-phase BUCK circuit can also be understood as multiple BUCK circuits.

For the above-mentioned multi-phase BUCK circuits 101-104, the internal structure of each phase of the BUCK circuit may be the same. The following takes the BUCK circuit 101 as an example to describe the internal structure of each BUCK circuit.

In some possible implementation manners, as shown in FIG. 3, the BUCK circuit 101 includes: a BUCK control circuit B and an inductor L. Wherein, the BUCK control circuit B is connected to the multi-phase controller 100 and one end of the inductor L, and the other end of the inductor L is connected to the switch module 20.

Illustratively, as shown in FIG. 3, in the BUCK circuit 101, the BUCK control circuit B may include a first transistor Q1 and a second transistor Q2. The gate of the first transistor Q1 is connected to the multiphase controller 100, the first electrode of the first transistor Q1 is connected to the power supply terminal VIN, the second electrode of the first transistor Q1 is connected to node a; the gate of the second transistor Q2 is connected to The multi-phase controller 100 is connected, the first pole of the second transistor Q2 is connected to the node a, and the second pole of the second transistor Q2 is connected to the ground terminal. One end of the inductor L is connected to the node a, and the other end of the inductor L is connected to the switch module 20 as the output end of the BUCK circuit 101 (that is, the power supply output end X1).

Of course, other related electronic devices, such as capacitors, resistors, etc., can also be provided in the BUCK circuit 101 according to actual needs, which is not specifically limited in this application.

It should be noted that the above-mentioned first transistor Q1 and second transistor Q2 may be N-type transistors or P-type transistors; they may be enhancement-type transistors or depletion-type transistors; the above-mentioned transistors (Q1, Q2) The first electrode can be a source electrode and the second electrode is a drain electrode; or the first electrode can be a drain electrode and the second electrode is a source electrode, which is not limited in the present invention.

On this basis, it can be understood that the power management unit (PMU) is an important component of the power supply system. For the power supply system 01 of the present application, in some embodiments, as shown in FIG. 4, the power supply The module 10 may include a PMU, and the multi-phase controller 100 and the BUCK control circuit B of the multi-phase BUCK circuits 101-104 can be arranged in the PMU to improve the integration of the entire power supply system. Of course, other related control circuits (such as a clock signal control circuit, etc.) or detection modules are also provided in the PMU, which is not limited in this application.

In addition, taking the BUCK circuit 101 as an example, for the inductance L connected to the power supply output terminal X1 in the BUCK circuit 101, the inductance value (also referred to as the inductance value) of the inductance L is directly related to the output efficiency of the BUCK circuit 101. When the output current of the BUCK circuit 101 is large, the use of an inductance with a smaller inductance can make the BUCK circuit 101 have a higher output efficiency; when the output current of the BUCK circuit 101 is small, the use of an inductance with a larger inductance can make the BUCK circuit 101 The circuit 101 has a higher output efficiency. In other words, when the output current is large, the output efficiency of the BUCK circuit with a smaller inductance is higher than that of the BUCK circuit with a larger inductance (other setting conditions are the same); in the case of a smaller output current In this case, the output efficiency of a BUCK circuit with a larger inductance is higher than that of a BUCK circuit with a smaller inductance (other setting conditions are the same).

Based on this, in some possible implementation manners, the inductance values of the inductances in the multi-phase BUCK circuits 101-104 may be set to be different. In this case, when the switch module 20 configures the on-off between the multi-phase BUCK circuit 101-104 and the load module in the SOC 30, the heavy load module in the SOC 30 can be selectively controlled with a smaller inductance. The conduction between the inductance BUCK circuits is to control the conduction between the light load module in the SOC and the BUCK circuit with a larger inductance inductance, so as to improve the output efficiency of the BUCK circuit, thereby increasing the efficiency of the power supply.

Of course, in some possible implementation manners, it is also possible to set the inductance values of the inductances in the multi-phase BUCK circuits 101-104 to be the same.

For the switch module 20 in the present application, in some possible implementation manners, the switch module 20 may be a plurality of separate switches. In some possible implementation manners, the switch module 20 may also be an integrated device of multiple switches; for example, the switch module 20 may be a separate external chip, may also be built into the SOC 30, or may be built into the PMU. Wherein, the number of channels formed by the switch inside the switch module 20 depends on the number of power supply output terminals (or BUCK circuits).

In some embodiments, as shown in FIG. 5, the switch module 20 may be composed of multiple switch units (such as U1, U2), the input terminals of different switch units are connected to different BUCK circuits, and the output terminal of each switch unit Both are connected to SOC 30.

Schematically, as shown in FIG. 5, the power supply module 10 includes 4-phase BUCK circuits 101-104, and the 4-phase BUCK circuits 101-104 are connected to two load modules in the SOC 30 through the switch module 20. The two loads The modules are CPU_B and CPU_L, respectively; the switch module 20 may include a first switch unit U1 and a second switch unit U2. The input terminal of the first switch unit U1 is connected to the output terminals of the BUCK circuits 101 and 102 (that is, the power supply output terminals X1 and X2), and the output terminal of the first switch unit U1 is connected to both CPU_B and CPU_L in the SOC 30 The input terminal of the second switch unit U2 is connected to the output terminals of the BUCK circuit 103, 104 (that is, the power supply output terminals X3, X4), and the output terminal of the second switch unit U2 is connected to both CPU_B and CPU_L in the SOC 30.

In addition, in some possible implementation manners, the aforementioned SOC 30, the multi-phase controller 100 (or PMU), and the switch module 20 may be connected by a bus. The bus may include an I2C bus (inter-integrated circuit, I2C), a power supply Management interface (system power management interface, SPMI), universal asynchronous receiver/transmitter (UART), mobile industry processor interface (mobile industry processor interface, MIPI), etc., so as to ensure the SOC in the above-mentioned power supply system 01 30. The multi-phase controller 100 (or PMU) and the switch module 20 can complete the transmission of related signals through a corresponding communication protocol.

In addition, compared with the prior art, in terms of connecting the load module in the SOC to a fixed BUCK circuit (that is, there is only one power supply mode), in this application, by setting the switch module 20, the load can be supplied to the load according to actual needs. The module selectively configures one-phase or multi-phase BUCK circuits, so that the power supply system 01 can have a variety of combined power supply modes.

Illustratively, taking the power supply to CPU_B and CPU_L through the 4-phase BUCK circuit 101-104 shown in FIG. 5 as an example, refer to Table 1. In this case, through the control of the switch module 20, the power supply system 01 can implement 15 types Power supply.

Specifically, as shown in the column of the number of phases configured for the BUCK circuit in Table 1, column 1 means that neither CPU_B nor CPU_L is equipped with BUCK circuits; column 2 means that CPU_B is not equipped with BUCK circuits, and CPU_L is equipped with 1-phase BUCK circuits; column 3 means that CPU_B is not equipped with BUCK circuits. Configure BUCK circuit, CPU_L configures 2-phase BUCK circuit; column 4 indicates that CPU_B does not configure BUCK circuit, and CPU_L configures 3-phase BUCK circuit; column 5 indicates that CPU_B does not configure BUCK circuit, and CPU_L configures 4-phase BUCK circuit; column 6 indicates that CPU_B configures 1-phase BUCK circuit, CPU_L does not configure BUCK circuit; column 7 indicates that CPU_B is configured with 1-phase BUCK circuit, and CPU_L is configured with 1-phase BUCK circuit; column 8 indicates that CPU_B is configured with 1-phase BUCK circuit, and CPU_L is configured with 2-phase BUCK circuit; column 9 indicates that CPU_B is configured with 1-phase BUCK circuit, CPU_L configures a 3-phase BUCK circuit; column 10 indicates that CPU_B configures a 2-phase BUCK circuit, and CPU_L does not configure a BUCK circuit; column 11 indicates that CPU_B configures a 2-phase BUCK circuit, and CPU_L configures a 1-phase BUCK circuit; column 12 indicates that CPU_B configures a 2-phase BUCK circuit, CPU_L configures a 2-phase BUCK circuit; column 13 indicates that CPU_B configures a 3-phase BUCK circuit, and CPU_L does not configure a BUCK circuit; column 14 indicates that CPU_B configures a 3-phase BUCK circuit, and CPU_L configures a 1-phase BUCK circuit; column 15 indicates that CPU_B configures a 4-phase BUCK circuit, CPU_L does not configure BUCK circuit. It should be noted that other BUCK circuit combinations can also be used for power supply, which is not specifically limited in this application.

Table 1

In the following, referring to Table 2, the load modules in the SOC in the prior art are set with fixed single-phase and multi-phase BUCK circuits through specific examples, and in this application, the switch module 20 is set to selectively supply the load according to the actual power supply requirements. The module is equipped with one-phase or multi-phase BUCK circuits to reduce the number of BUCK circuits (that is, the number of phases) for specific comparison and description.

As shown in Table 2, take the load modules in the SOC: CPU_B, PERI (external injection module), MODEM (modulator), NPU, CPU_M, and GPU to configure the number of phases of the BUCK circuit as an example. In the prior art, in order to meet all scenarios (ie application scenarios), a 2-phase BUCK circuit is configured for CPU_B, a 2-phase BUCK circuit is configured for PERI, a 3-phase BUCK circuit is configured for MODEM, a 2-phase BUCK circuit is configured for NPU, and 2 phases are configured for CPU_M. Phase BUCK circuit, a 2-phase BUCK circuit is configured to the GPU, that is, a total of 13 phase BUCK circuits are required.

With the technical solution of this application, only 7-phase BUCK circuits need to be set up in total (for example, 7-phase BUCK circuits are required in the column of total phase number in Table 2), which can meet most (over 99%) scenarios; that is, through switches The module 20 can select one-phase or multi-phase BUCK circuits among the 7-phase BUCK circuits to meet the power supply requirements of load modules in different scenarios.

Specifically, referring to Table 2, in the desktop static scenario, only need to configure 1-phase BUCK circuit to PERI, 1-phase BUCK circuit to MODEM, 1-phase BUCK circuit to CPU_M, 1-phase BUCK circuit to GPU, CPU_B NPU and NPU do not need to configure the BUCK circuit; that is, in the desktop static scene, only the 4-phase BUCK circuit needs to be configured in the 7-phase BUCK circuit.

Please refer to the figure for specific configuration. 2. I won't repeat it here.

Table 2

To sum up, compared with the prior art requiring a 13-phase BUCK circuit, the technical solution of this application only needs to be equipped with a 7-phase BUCK circuit, that is, a 6-phase BUCK circuit is reduced, and the use of a BUCK circuit is improved. The efficiency of the power supply is improved.

In addition, it can be understood that, as shown in Table 2, although the 7-phase BUCK circuit is set up using the technical solution of this application, in actual applications, it is not necessary to use the 7-phase BUCK circuit according to the actual application scenarios. All configuration, that is, the 7-phase BUCK circuit may only need part of the BUCK circuit for power supply, and some of the BUCK circuit does not supply power; for example, in a desktop static scenario, only the 4-phase BUCK circuit needs to be configured for power supply. In this case, the 3-phase BUCK circuit The circuit does not need to be powered.

The embodiment of the present application also provides a power supply method suitable for the above-mentioned power supply system. As shown in FIG. 6, the power supply method includes:

Wherein, the first application program is one of the application programs installed on the terminal device.

The above-mentioned BUCK configuration information includes the configuration information of the power supply module and the switch module. The SOC configures the power supply module and the switch module according to the BUCK configuration information, and the power supply module and the switch module realize power supply to one or more load modules in the SOC based on the configuration. At this time, the one or more loads are adapted to the currently opened first application program.

For example, taking a mobile phone to watch a video as an example, when a video application is running, the small CPU core and GPU in the SOC need to be powered on. Based on this, when the user opens the icon of the video application on the terminal device, the SOC recognizes the video application and obtains the BUCK configuration information that is adapted to the video application. The SOC controls the power supply module and switch according to the BUCK configuration information. The module is configured, and the power supply module and the switch module supply power to the small CPU core and GPU in the SOC based on the configuration.

In addition, regarding the process of obtaining BUCK configuration information adapted to the first application in step 11:

In some possible implementation manners, obtaining the BUCK configuration information adapted to the first application program may be: downloading the BUCK configuration information adapted to the first application program from the network side. For example, it may be downloading BUCK configuration information adapted to the first application from a cloud database; for another example, it may be downloading BUCK configuration information adapted to the first application from a large network database. Among them, for the BUCK configuration information located on the network side, it can be generated by the SOC in the terminal device through self-learning and uploaded to the network side; it can also be obtained through manual detection and debugging and uploaded to the network side.

In some possible implementation manners, obtaining the BUCK configuration information adapted to the first application program may be: reading the BUCK configuration information from a locally stored BUCK configuration library. Among them, for the BUCK configuration information in the BUCK configuration library stored locally, it can be downloaded from the network side, or generated by the SOC through self-learning (the specific learning process of the SOC can refer to the relevant content provided in the subsequent embodiments. ).

Step 12. Configure the first parameter set of the power supply module and the switch module according to the above-mentioned BUCK configuration information.

The above-mentioned first parameter set is used to control the power supply module and the switch module to output the current of one or more power supply output terminals to the SOC.

Illustratively, the SOC configures the first parameter set of the power supply module and the switch module according to the acquired BUCK configuration information adapted to the first application program, and the power supply module and the switch module combine one or more parameters under the control of the first parameter set. The current of each power supply output terminal is output to the SOC, so as to meet the normal power supply of the load module in the SOC that is adapted to the first application program, thereby ensuring the normal operation of the first application program.

Taking the aforementioned mobile phone watching video as an example, the SOC configures the control parameters of the power supply module and the switch module (that is, the first parameter set) according to the acquired BUCK configuration information, so as to control the CPU cores and GPUs in the SOC with one or more The channels between the two power supply output terminals are turned on, and the power supply module supplies power to the small CPU cores and the GPU through the turned on channels. For example, the channel between the CPU core and the power supply output terminal X1 is turned on, and the channel between the CPU core and the power supply output terminal X2 is turned on. At this time, the power supply module sends to the CPU through the power supply output terminal X1 and the power supply output terminal X2 respectively. The small core and GPU output current for power supply.

In addition, regarding the above-mentioned first parameter set used to control the power supply module and the switch module to output the current of one or more power supply output terminals to the SOC:

In the case where the inductance values of the inductances in the BUCK circuit corresponding to each power supply output terminal in the power supply system are not completely the same, in some possible implementation manners, the above-mentioned first parameter set can be specifically used to control the power supply module and the switch module. The power supply output terminal corresponding to the BUCK circuit with smaller inductance is connected to the heavy load module in the SOC, and the power supply output terminal corresponding to the BUCK circuit with larger inductance is connected to the light load module in the SOC to ensure that it is connected to the light load module in the SOC. The BUCK circuit connected to the heavy-duty module and the light-duty module has a higher output efficiency, thereby improving the power efficiency.

That is to say, among all load modules in the SOC that are adapted to the first application, if the load of the second load module is greater than the load of the third load module, and it is connected to the first power supply output terminal (it can be one or the same) When the inductance value of the inductance in the corresponding BUCK circuit is smaller than the inductance value of the inductance in the second power supply output terminal (either one or more) corresponding to the BUCK circuit, the first parameter set can be used The control power supply module and the switch module output the output current of the at least one first power supply output terminal to the second load module in the SOC, and output the output current of the at least one second power supply output terminal to the third load module in the SOC.

Illustratively, taking the power supply module 10 shown in FIG. 5 including a multi-phase controller 100 and 4- phase BUCK circuits 101, 102, 103, and 104 as an example, the inductors in the 4- phase BUCK circuits 101, 102, 103, and 104 can be set The sense values of are respectively L1, L2, L3, L4, and L1, L2, L3, L4 are not completely the same; for example, it can be L1=L2>L3=L4, L1>L2=L3=L4, L1>L2>L3 =L4, L1>L2>L3>L4 and so on.

Taking L1>L2>L3>L4 as an example, when power is supplied to CPU_B and CPU_L in the SOC through the 4-phase BUCK circuit 101-104, when CPU_B is working in light load mode and CPU_L is working in heavy load mode, the power supply can be configured The first parameter set of module 10 and switch module 20 controls BUCK circuit 101 to supply power to CPU_B, and BUCK circuit 104 to supply power to CPU_L; when CPU_B works in heavy load mode and CPU_L works in light load mode, power supply module 10 can be configured And the first parameter set of the switch module 20 to control the BUCK circuits 103 and 104 to supply power to the CPU_B, and the BUCK circuit 101 to supply power to the CPU_L.

In summary, using the power supply method of the present application, when the first application is opened on the terminal device, the first application can be identified to obtain the BUCK configuration information adapted to the first application, and according to The BUCK configuration information configures the parameters of the power supply module and the switch module (that is, the above-mentioned first parameter set), and selectively controls the output of the current of one or more power supply output terminals (that is, the power supply unit) of the power supply module to the SOC, so as to satisfy The normal power supply of the load module in the SOC adapted to the first application program ensures the normal operation of the first application program, reduces the number of power supply units, and improves the power supply efficiency.

Considering that during the running process of the first application program, the user may load different functions, which may increase the load of the load module in the SOC that is adapted to the first application program, thereby causing the problem of insufficient power supply. In order to solve this technical problem, in some embodiments, as shown in FIG. 7, the power supply method of the present application further includes after the above step S12:

Step 13. During the running of the first application program, detect that the output current of the power supply output terminal connected to the first load module is greater than the first threshold.

Wherein, the above-mentioned first load module is any one of at least one load module in the SOC that is adapted to the first application program.

Illustratively, during the running process of the first application program, the power supply output terminal (which can also be said to be the path where the power supply output terminal is located) connected to the load module adapted to the first application program can be performed through a power supply module (such as a PMU) or a switch module. The output current of) is monitored and fed back to the SOC; the SOC detects whether the output current of the power supply output terminal connected to any load module adapted to the first application program (ie, the aforementioned first load module) is greater than the first threshold.

For example, taking the maximum output current of the power supply output end of 4A as an example, the first threshold value can be set to 3.5A. The PMU detects that the output current of the power supply output terminal connected to any load module (that is, the first load module) that is adapted to the first application program is 3.6A, and feeds back the 3.6A to the SOC, and judges the 3.6A and 3.6A through the SOC. The first threshold is between 3.5A.

When it is detected in step 13 that the output current of the power supply output terminal connected to the first load module is greater than the first threshold, step 14 is executed: configure the second parameter set of the power supply module and the switch module to control the adaptation to the first application program The output currents of the power supply output terminals connected to all load modules are not greater than the first threshold.

The above-mentioned second parameter set is used to control the power supply module and the switch module to add a power supply output terminal with no output current to communicate with the first load module.

Illustratively, when the SOC detects that the output current of the first power supply output terminal connected to the first load module (that is, any load module adapted by the first application) is greater than the first threshold, the parameters of the power supply module and the switch module are configured (I.e. the second parameter set mentioned above), control to add a power supply output terminal without output current to connect with the first load module to reduce the output current of the first power supply output terminal, by controlling each load adapted to the first application The detection and control of the output current of the power supply output connected by the module, thereby making the output current of the power supply output terminals connected to all load modules adapted to the first application program not greater than the first threshold.

It should be noted here that the above process of adding a power supply output terminal with no output current to the first load module may be a one-time addition process, or it may be a multiple addition process, as long as it is ensured that the power supply output without output current is added. After the terminal is connected with the first load module, the current of each power supply output terminal connected with the first load module is not greater than the first threshold.

For example, when the SOC receives that the output current of the first power supply output terminal connected to the first load module is 3.6A greater than the first threshold 3.5A, it configures the parameters of the power supply module and the switch module (that is, the above-mentioned second parameter set), and adds A second power supply output terminal with no output current is connected to the first load module. At this time, the second power supply output terminal shares part of the load of the first power supply output terminal, so that the output current of the first power supply output terminal decreases. The output current of the first power supply output terminal and the second power supply output terminal connected by a load module is not greater than the first threshold 3.5A.

For another example, when the SOC detects that the output current of the first power supply output terminal connected to the first load module is 4A (that is, the first power supply output terminal is supplying power with the maximum output current) is greater than the first threshold 3.5A, then the configuration For the parameters of the power supply module and the switch module (that is, the above-mentioned second parameter set), a second power supply output terminal without output current is added to connect with the first load module. At this time, the second power supply output terminal shares the part of the first power supply output terminal Load, so that the output current of the first power supply output terminal decreases, but at this time, it is detected that the output current of the first power supply output terminal is 3.6A, that is, the output current is still greater than the first threshold 3.5A. In this case, continue to configure the parameters of the power supply module and the switch module (that is, the above-mentioned second parameter set), and add a third power supply output terminal with no output current to communicate with the first load module, so that the output of the first power supply output terminal The current is reduced, so that the output current of the first power supply output terminal, the second power supply output terminal, and the third power supply output terminal connected with the first load module are not greater than the first threshold value 3.5A.

After controlling through step 14 that the output current of the power supply output terminals connected to all load modules adapted to the first application program is not greater than the first threshold, then step 15 is performed: generating the BUCK configuration according to the current parameter set of the power supply module and the switch module information.

Regarding the generation of BUCK configuration information according to the current parameter set of the power supply module and the switch module in step 15 above, it can be understood that the current parameter set of the power supply module and the switch module can control each SOC that is adapted to the first application. The load modules are respectively connected with one or more power supply output terminals to meet the normal power demand of each load module.

For example, referring to Figure 5, taking the two load modules that are adapted to the first application program are CPU_B and CPU_L as an example, the power supply module and the switch module can connect the power supply output terminals X1, X3 and CPU_B under the control of the current parameter set. Connected, connect the power supply output terminal X2 with the control CPU_L to meet the power demand of CPU_B and CPU_L.

In addition, in some possible implementation manners, after generating the BUCK configuration information according to the current parameter set of the power supply module and the switch module in step 15, the BUCK configuration information can be stored in the local BUCK configuration library. When the first application is subsequently used, the BUCK configuration information can be directly obtained from the local BUCK configuration library.

In some possible implementation manners, after generating the BUCK configuration information according to the current parameter set of the power supply module and the switch module in step 15, the BUCK configuration information can be uploaded to the network test (such as a large network database) for the user (can This user can also be other users) download the BUCK configuration information through the network side.

In addition, when it is detected in step 13 that the output current of the power supply output terminal connected with the first load module is not greater than the first threshold, the entire power supply system maintains the existing state, and the power supply module and the switch module follow the current state in step 12. The configured first parameter set only needs to continuously supply power to the SOC (that is, keep step 12).

The following provides an implementation manner in which the SOC generates BUCK configuration information adapted to the first application program through self-learning. As shown in FIG. 8, the power supply method of the present application further includes before the above step S11:

Step 21: Determine whether the first application currently opened on the terminal device is opened for the first time.

Illustratively, when the user is using the first application program on the terminal device, the SOC identifies the first application program currently opened on the terminal device and determines whether the first application program is opened for the first time.

Step 22: If the first application is started for the first time, configure the initial parameter set of the power supply module and the switch module.

The aforementioned initial parameter set is used to control each load module in the SOC to communicate with one of the multiple power supply output terminals.

It can be understood here that when each load module is controlled to communicate with one of the multiple power supply output terminals through the initial parameter set, the number of power supply output terminals in the power supply system must be greater than or equal to the number of load modules in the SOC.

Illustratively, in step 22, when the SOC judges that the currently opened first application program is opened for the first time, it configures the initial parameter set of the power supply module and the switch module, and the power supply module and the switch module set the SOC under the control of the initial parameter set. Each load module in the load module is respectively connected to a power supply output terminal. Of course, different load modules are connected to different power supply output terminals.

For example, referring to Figure 4, take the four load modules of CPU_B, CPU_L, GPU, and NPU in the SOC as an example (the output terminals Y1, Y2, Y3, and Y4 of the switch module 20 are respectively connected to the four load modules), and power is supplied through configuration The initial parameter set of module 10 and switch module 20 can control CPU_B to connect with power supply output terminal X1, CPU_L to connect with power supply output terminal X2, GPU to connect with power supply output terminal X3, and NPU to connect with power supply output terminal X4.

Step 23: Detect whether the output current of the power supply output terminal connected to each load module is greater than the second threshold.

Illustratively, the output current of the power supply output terminal (or the path where the power supply output terminal is located) connected to each load module in the SOC can be monitored and fed back to the SOC through a power supply module (such as a PMU) or a switch module. It is detected by the SOC whether the output current of the power supply output terminal connected to each load module is greater than the second threshold.

For example, referring to Figure 4, the PMU monitors that the output current of the power supply output terminal X1 connected to CPU_B is 4A, the output current of the power supply output terminal X2 connected to CPU_L is 3A, the power supply output terminal X3 connected to the GPU and the power supply output terminal X3 connected to the NPU There is no output current at the power supply output terminal X4, and the monitoring result is fed back to the SOC, and the SOC detects whether the output current fed back is greater than the second threshold.

It should be noted that the foregoing second threshold may be the same as or different from the foregoing first threshold, which is not specifically limited in this application, and can be selected and set according to actual needs. In the following example, the second threshold is the same as the aforementioned first threshold, both of which are 3.5A.

It can be understood here that the load module connected to the power supply output terminal with output current is the load module adapted to the first application program currently opened on the terminal device; in other words, the load adapted to the first application program The power supply output terminal connected to the module has output current. For example, the aforementioned CPU_B connected to the power supply output terminal X1 with an output current of 4A and CPU_L connected to the power supply output terminal X2 with an output current of 3.5A are load modules adapted to the first application currently opened on the terminal device.

In addition, for the load module connected to the power supply output terminal with no output current, that is, the load module is not a load module adapted to the first application level; in this case, the power supply output terminal with no output current can be configured Disconnect from the load module to configure the power output terminal without output current to other load modules when other load modules need to be used (such as insufficient power supply); of course, the power output terminal and load without output current can also be maintained When connecting between modules, when other load modules need to be used (for example, the power supply is insufficient), directly configure the power supply output terminal with no output current to other load modules.

When it is detected in step 23 that the output current of the power supply output terminal connected to the first load module (any one of the at least one load module adapted to the first application in the SOC) is greater than the second threshold, step 24: Configure The second parameter set of the power supply module and the switch module is used to control that the output current of the power supply output terminals connected to all load modules adapted to the first application program is not greater than the second threshold.

The above-mentioned second parameter set is used to control the power supply module and the switch module to add a power supply output terminal with no output current to communicate with the first load module. Wherein, the first load module is any one of at least one load module in the SOC that is adapted to the first application program.

Illustratively, when the SOC detects that the output current of the first power supply output terminal connected to any load module (ie, the aforementioned first load module) adapted to the first application program is greater than the second threshold, the power supply module and the switch module are configured Parameter (that is, the above-mentioned second parameter set), control to add a power supply output terminal without output current to connect with the first load module to reduce the output current of the first power supply output terminal. The output current of the power supply output terminal connected to the load module is detected and controlled so that the output current of the power supply output terminal connected to all load modules adapted to the first application program is not greater than the second threshold.

The process of the above step 24 is basically the same as the process of the foregoing step 13. For related content, please refer to the corresponding part in the foregoing step 13, which will not be repeated here.

After the output current of the power supply output terminals connected to all load modules that are adapted to the first application program are controlled in step 24 to be not greater than the second threshold, step 25: generate a BUCK configuration based on the current parameter set of the power supply module and the switch module information.

In addition, when it is detected in step 23 that the power supply output terminal connected to each load module is not greater than the first threshold (that is, when the output current of the power supply output terminal connected to the first load module is not greater than the first threshold), Then proceed directly to step 25: generate BUCK configuration information according to the current parameter set of the power supply module and the switch module.

In some possible implementations, after the BUCK configuration information is generated according to the current parameter set of the power supply module and the switch module in step 25, the BUCK configuration information can be stored in the local BUCK configuration library; When the terminal device subsequently uses the first application program, it can directly obtain the BUCK configuration information from the local BUCK configuration library, so that it can quickly and timely configure the power supply module and switch module to switch the power supply channel, thereby effectively ensuring the efficiency of power supply and the power supply system Power supply capacity.

In some possible implementation methods, after generating the BUCK configuration information according to the current parameter set of the power supply module and the switch module in step 25, the BUCK configuration information can be uploaded to the network test (such as a large network database) for other users to pass. The network side downloads directly to obtain the BUCK configuration information, so as to achieve the purpose of resource sharing.

For other related content of the above step 25, please refer to the corresponding part in the above step 15, which will not be repeated here.

Schematically, the power supply method in the present application will be further described through specific embodiments in conjunction with the power supply system shown in FIG. 5 and with reference to FIG. 9 below.

Step 31. Click the first application.

Illustratively, the user clicks on the first application on the terminal device to open the first application.

Step 32: Identify the first application program.

Illustratively, the SOC identifies the first application currently opened on the terminal device.

Step 33: Determine whether the first application is opened for the first time.

Illustratively, the SOC determines whether the first application currently opened on the terminal device is opened for the first time.

In the case where the SOC determines that the first application is opened for the first time in step 33, step 34 is performed: configuring the initial parameter set of the power supply module and the switch module.

The aforementioned initial parameter set is used to control each load module in the SOC to communicate with one of the multiple power supply output terminals. Other related content of this step 34 can be a parameter of the aforementioned step 22, which will not be repeated this time.

Step 35 is performed on the basis of step 34: it is detected whether the output current of the power supply output terminal connected with each load module is greater than the second threshold.

Illustratively, the output current of the power supply output terminal connected to each load module in the SOC is monitored by the PMU, and fed back to the SOC, and whether the feedback output current is greater than the second threshold is detected by the SOC. Other related content of this step 35 can be a parameter of the aforementioned step 23, which will not be repeated this time.

When it is detected in step 35 that the output current of the power supply output terminal connected to the first load module is greater than the second threshold, step 36: configure the second parameter set of the power supply module and the switch module to control the adaptation to the first application The output currents of the power supply output terminals connected to all load modules of the load modules are not greater than the second threshold.

The above-mentioned second parameter set is used to control the power supply module and the switch module to add a power supply output terminal with no output current to communicate with the first load module. The first load module is any one of at least one load module in the SOC that is adapted to the first application program. Other related content of this step 36 can be a parameter of the aforementioned step 24, which will not be repeated this time.

After controlling through step 36 that the output current of the power supply output terminals connected to all load modules adapted to the first application program is not greater than the second threshold, then step 37: generate a BUCK configuration based on the current parameter set of the power supply module and the switch module information.

When it is detected in step 35 that the power supply output terminal connected to each load module is not greater than the first threshold (that is, when the output current of the power supply output terminal connected to the first load module is not greater than the first threshold), then the step is directly executed 37: Generate BUCK configuration information according to the current parameter set of the power supply module and the switch module.

Illustratively, after generating the BUCK configuration information according to the current parameter set of the power supply module and the switch module in step 37, the BUCK configuration information can be stored in the local BUCK configuration library. Other related content of the foregoing step 37 can be a parameter of the foregoing step 15, and will not be repeated this time.

In addition, if it is determined in the above step 33 that the first application is not opened for the first time (that is, the first application has been opened before this time), then step 38 is performed: obtaining an adaptation to the first application BUCK configuration information.

Illustratively, when the SOC determines that the first application is not opened for the first time, it obtains the BUCK configuration information adapted to the first application from the BUCK configuration library. Wherein, the BUCK configuration information in the BUCK configuration library may be the BUCK configuration information generated through the above steps 31-37 when the first application is first opened.

Step 39: Configure the first parameter set of the power supply module and the switch module according to the BUCK configuration information.

The first parameter set is used to control the power supply module and the switch module to output the current of one or more power supply output terminals to the SOC. Other related content of this step 39 can be a parameter of the aforementioned step 12, which will not be repeated this time.

Step 40: During the operation of the first application program, detect whether the output current of the power supply output terminal connected to the first load module is greater than a first threshold.

The above-mentioned first load module is any one of at least one load module in the SOC that is adapted to the first application program. Other related content of this step 40 can be a parameter of the aforementioned step 13, which will not be repeated this time.

When it is detected in step 40 that the output current of the power supply output terminal connected with the first load module is greater than the first threshold, step 41: configure the second parameter set of the power supply module and the switch module to control the adaptation to the first application The output currents of the power supply output terminals connected to all load modules are not greater than the first threshold.

The above-mentioned second parameter set is used to control the power supply module and the switch module to add a power supply output terminal with no output current to communicate with the first load module. Other related content of this step 41 can be a parameter of the aforementioned step 14, which will not be repeated this time.

When it is controlled through step 41 that the output current of the power supply output terminal connected with all load modules adapted to the first application program is not greater than the first threshold, then step 42 is performed: generating the BUCK configuration according to the current parameter set of the power supply module and the switch module information.

In some achievable manners, after the BUCK configuration information is generated according to the current parameter set of the power supply module and the switch module through the above step 42, the newly generated BUCK configuration information can be stored in the BUCK configuration library as the new BUCK configuration information.

In addition, when it is detected in step 40 that the output current of the power supply output terminal connected with the first load module is not greater than the first threshold, the entire power supply system maintains the existing state, and the power supply module and the switch module follow the current state in step 39 The configured first parameter set only needs to continuously supply power to the SOC.

The normal power supply of the load module ensures the normal operation of the first application program, while reducing the number of power supply units, thereby improving power supply efficiency.

In some possible implementation manners, the above-mentioned obtaining module 201 is specifically used to download BUCK configuration information from the network side; or, to read BUCK configuration information from a locally stored BUCK configuration library.
