Detailed ways

In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below through embodiments and in conjunction with the accompanying drawings. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

In addition, the technical solutions described in the embodiments of the present application may be combined arbitrarily if there is no conflict.

The following is a basic introduction to the two power supply methods of the current power system.

FIG. 1 is a first structural schematic diagram of a power consumption system provided in the prior art. As shown in Figure 1, the power consumption system supports an independent power supply scheme. Specifically, after the power is input into the power management unit, N controllable voltage conversion modules are used to output N circuits of power supply, which are respectively supplied to each power consumption unit, wherein these power consumption units may belong to the same chip. The power supply of each power consumption unit is independent. When the performance monitoring unit of a power consumption unit decides that the operating frequency of the power consumption unit needs to be adjusted and triggers a corresponding voltage adjustment, the performance monitoring unit sends the target voltage value Vt to be adjusted to the power consumption management unit in the chip, and the power After receiving the instruction, the power management unit sends an instruction to the power management unit, and the power management unit controls the corresponding voltage conversion module to adjust the power supply voltage to Vt. If the purpose of this voltage regulation is to increase the voltage and frequency, the frequency of the power consumption unit will increase after the adjustment of the supply voltage is completed. If the purpose of voltage regulation this time is to reduce voltage and frequency, the frequency of the power consumption unit is reduced first, and then Vt is sent to the power management unit to realize voltage reduction. If the purpose of this voltage regulation is to increase the voltage and frequency, the power consumption unit waits for the power supply voltage to be adjusted to Vt, and then increases the operating frequency.

It should be noted that, for the above-mentioned independent power supply scheme, multiple voltage conversion modules should be set in the power management unit, multiple independent power supply pins should be set on the chip pins, and multiple independent power supply pins should be set inside the chip. Network, the voltage conversion module should be set separately on the interconnection signal between power units. The complexity of the system is large, the power supply overhead and cost are high, and it cannot be adapted and deployed on complex chips with a large number of internal power consumption units.

Fig. 2 is a second structural schematic diagram of a power consumption system provided in the prior art. As shown in Figure 2, the power consumption system supports a combined power supply scheme. Similar to the independent power supply, in the combined power supply solution, after the power is input to the power management unit, M controllable voltage conversion modules are used to output M power supplies. The difference is that the M-circuit power supply is no longer directly shared with each power-consuming unit. Instead, the power consumption units are grouped, and each group forms a voltage domain, and M circuits supply power to all power consumption units in the voltage domain. When the performance monitoring unit of a power consumption unit in a certain voltage domain decides that the operating frequency of the power consumption unit needs to be adjusted to Ft, and the corresponding working voltage is Vt when Ft works, the performance monitoring unit k sends The power management unit sends the target voltage value Vt that needs to be adjusted. After receiving the instruction, the power management unit integrates the operating voltage requirements of all N power-consuming units in the voltage domain, and takes the maximum target operating voltage value Vmax to the power management unit. The unit sends an instruction, and the power management unit controls the voltage conversion module to adjust the supply voltage to Vmax. If the purpose of this voltage regulation is to increase the voltage and frequency, the frequency of the power consumption unit will increase after the voltage adjustment is completed. If the adjusted Ft is lower than the previous working frequency, the frequency of the power consumption unit is lowered first, and then the target voltage value to be adjusted is sent to the power management unit. If the Ft of this voltage adjustment is higher than the previous working frequency, the power consumption unit waits for the power supply voltage to be adjusted to Vmax (>=Vt), and then raises the working frequency to Ft.

It should be noted that, for the above combined power supply scheme, since multiple power consumption units in the same voltage domain share the same power supply, the power supply voltage of the final voltage domain is the maximum voltage value of each power consumption unit, and some working voltage requirements are relatively high. For low power consumption units, the power supply voltage is higher than the required voltage, and the existence of excess voltage causes an increase in power consumption.

In an embodiment of the present application, a power consumption system is provided, which can reduce system power consumption, which will be described in detail below.

FIG. 3 is a first structural schematic diagram of a power consumption system provided by an embodiment of the present application. As shown in Figure 3, in the embodiment of the present application, the power consumption system includes: multiple power consumption units 101 belonging to the same voltage domain, and multiple performance management units 102 connected to the multiple power consumption units 101 in one-to-one correspondence ;

A power management unit 103 connected to multiple power consumption units 101, the power management unit 103 is used to provide the same working voltage for multiple power consumption units 101;

Each performance management unit 102 is configured to determine the target operating frequency corresponding to the power consumption unit connected to it according to the working voltage, and control the power consumption unit 101 connected to it to work at the corresponding target working frequency.

It should be noted that, in the embodiment of the present application, referring to FIG. 4 , the power consumption system can be divided into M voltage domains, M is a natural number not less than 1, and a certain number of power consumption units 101 can be included in the voltage domain 0 , the working voltages of the power consumption units 101 in the same voltage domain are the same.

It should be noted that, in the embodiment of this application, the specific power consumption unit 101 and the number of power consumption units 101 can be set according to actual needs and application scenarios. It is consistent with the number of power consumption units 101 and connected in one-to-one correspondence.

In the embodiment of the present application, referring to FIG. 4 , the power management unit 103 includes: a voltage conversion module 1031 , and the voltage conversion module is configured to convert an input voltage of a power supply into an operating voltage. In addition, the power management unit 103 may also include voltage conversion modules corresponding to other voltage domains.

It should be noted that, in the embodiment of the present application, in order to provide the same working voltage to multiple power consumption units 101 belonging to the same voltage domain, a voltage conversion module 1031 can be deployed in the power management unit 103, so that through the voltage conversion module 1031 converts the input voltage of the power supply, and the converted operating voltage can be provided to each power consumption unit 101 , wherein the magnitude of the operating voltage can be changed by the power management unit 103 controlling the voltage conversion module 1031 .

It can be understood that, in the embodiment of the present application, for multiple power consumption units 101 belonging to the same voltage domain, the voltage conversion module 1031 provides the same working voltage, but in actual demand, the voltage requirement of each power consumption unit 101 There may be a difference, that is, the working voltage provided by the voltage conversion module 1031 may not match the actual working state of the power consumption unit 101, for example, the working voltage is too high. For this, each performance management unit 102 can determine the corresponding operating voltage according to the working voltage. The target operating frequency corresponding to the connected power consumption unit 101 is used for operating frequency control.

In the embodiment of the present application, each performance management unit 102 is also used to: obtain the operating voltage of the power consumption unit 101 connected to it when the working voltage exceeds the expected voltage value corresponding to the power consumption unit 101 connected to it. The corresponding current working frequency and maximum working frequency;

Calculating the first expected power consumption of the power consumption unit 101 connected to it at the operating voltage, operating at the corresponding current operating frequency, and the second expected power consumption operating at the corresponding maximum operating frequency;

In the case that the second expected power consumption is lower than the first expected power consumption, the maximum operating frequency is determined as the target operating frequency corresponding to the connected electric unit.

In the embodiment of the present application, each performance management unit 102 is also used to: separately calculate the duty cycle and dynamic power consumption of the power consumption unit 101 connected to it at the corresponding current operating frequency under the operating voltage;

Obtaining the maximum leakage current of the power consumption unit 101 connected to it under the working voltage;

Calculate the first expected power consumption according to the maximum leakage current, and the dynamic power consumption and duty cycle of the power consumption unit 101 connected to it working at the corresponding current working frequency under the working voltage;

The second expected power consumption is calculated according to the maximum leakage current, and the dynamic power consumption and duty cycle of the power consumption unit 101 connected to it working at the corresponding maximum working frequency under the working voltage.

FIG. 5 is a schematic diagram of a workflow of an exemplary performance management unit provided by an embodiment of the present application. As shown in Figure 5, in the embodiment of the present application, any performance management unit 103 can first obtain the current operating frequency Fc of the power consumption unit 101 connected to it, and at the same time obtain the working frequency of the power consumption unit 101 connected to it under the current voltage. The highest operating frequency Fmax. Generally, if Fmax>Fc, it means that the power consumption unit 101 can have a higher calculation speed when working under Fmax, but usually the calculation speed is not directly proportional to the operating frequency, and is also affected by the data and signals of the input and output channels. status impact. Further, the performance management unit 103 evaluates if the power consumption unit 101 is working at the frequency Fmax at this time, its final actual working and idle duty cycle Tmax, and if it continues to work at Fx, its duty cycle Tc. Then it can be drawn that when the operating voltage in the voltage domain is Vmax, the expected power consumption of the power consumption unit 101 to complete the current task at frequency Fmax is Tmax×(Pmax+Lmax), and the power consumption to complete the current task at frequency Fc is The expected power consumption is Tc×(Pc+Lmax). Wherein, Lmax is the maximum leakage current of the power consumption unit 101 under the current working voltage. If the power consumption required to work at the frequency Tmax is lower than the power consumption required to work at the frequency Tc, the performance management unit 103 determines the frequency Fmax as the target operating frequency corresponding to the power consumption unit 101, thereby controlling the increase in the working frequency of the power consumption unit 101 to frequency Pmax.

It should be noted that, in the embodiments of the present application, the ratio of Tmax to Tc is assumed to be ρ, and ρ is less than 1, as shown in the following formula:

P1=Tc×(Pc+Lmax) (1)

P2=Tmax×(Pmax+Lmax)≈ρTc×(Pc/ρ+Lmax)=Tc×(Pc+ρLmax) (2)

Among them, P1 is the expected power consumption of the power unit 101 working at the current working frequency under the working voltage, and P2 is the expected power consumption of the power unit working at the maximum working frequency under the working voltage. Since ρ<1, according to the above formula ( It can be seen from 1) and (2) that usually P2<P1, the power consumption can be reduced by up-frequency.

In the embodiment of the present application, each performance management unit 102 is also used to set the expected working voltage corresponding to the connected power unit 101 when the working voltage is the expected voltage value corresponding to the connected power unit 101. The frequency is determined as the corresponding target operating frequency; wherein, for each power consumption unit 101 , there is a corresponding relationship between the corresponding expected operating frequency and the expected voltage value.

It can be understood that, in the embodiment of the present application, the expected voltage value corresponding to each power consumption unit 101 corresponds to the expected operating frequency. For any power consumption unit 101, if the size of the working voltage is its corresponding expected voltage value , then it is most suitable to work at the expected operating frequency, therefore, its corresponding expected operating frequency can be directly determined as the target operating frequency.

In the embodiment of the present application, as shown in FIG. 4 , the power consumption system further includes: multiple switch units 104 belonging to the same voltage domain as the multiple power consumption units 101;

Each switch unit 104 is connected between a power consumption unit 101 and the power management unit 103, and is connected to the performance management unit 102 connected to the connected power consumption unit 101;

Each performance management unit 102 is also used to make a switching decision on the power consumption unit 101 connected to it, and generate a switching instruction according to the decision result and send it to the switching unit 104 connected to it;

Each switch unit 104 is configured to switch on or off the connection between the connected power consumption unit 101 and the power management unit 103 according to the received switch command.

It can be understood that, in the embodiment of the present application, as shown in FIG. The connected performance management unit 102 controls, and the performance management unit 102 controls whether the power consumption unit 101 connected to it is connected to the working voltage by sending a switch command to the switch unit 104 .

Exemplarily, in the embodiment of the present application, referring to the process shown in FIG. 5 , when the performance management unit 102 detects that the power consumption unit 101 has completed the current processing task, it can generate a decision result that the power consumption unit 101 is to be shut down, and According to the decision result, a switch instruction indicating that the power consumption unit 101 needs to be turned off is sent to the switch unit 104 connected to it, and the switch unit 104 can disconnect the connection between the power consumption unit 101 connected to it and the power management unit 103 according to the switch instruction , so as to stop supplying power to the power consumption unit 101 to shut down the power consumption unit 101 .

It can be understood that, in the embodiment of the present application, since the above-mentioned performance management unit 102 can control the operating frequency of the power consumption unit 101 connected to it according to the working voltage, for example, control the power consumption unit 101 to work at the maximum when the voltage is excessive. In this way, other modules that depend on the output of the power consumption unit 101 can start working as soon as possible, and enter the shutdown state as soon as possible, and the waiting time is shortened. Due to the increase of the current working frequency of the power consumption unit 101, other modules are reduced. Power consumption of downstream modules.

In the embodiment of the present application, as shown in FIG. 4 , the power consumption system further includes: a power consumption management unit 105, which is connected to each performance management unit 102 and the power management unit 103;

Each performance management unit 102 is also used to monitor the power consumption unit 101 connected to it, determine the expected operating frequency corresponding to the power consumption unit 101 connected to it, and, for the power consumption unit 101 connected to it, according to the corresponding expected operating frequency The working frequency determines the corresponding expected voltage value and sends it to the power management unit 105;

The power management unit 105 is configured to select the maximum voltage value from the received expected voltage values, and send the maximum voltage value to the power management unit 103;

The power management unit 103 is configured to adjust the working voltage to a maximum voltage value.

It should be noted that, in the embodiment of the present application, for any power-consuming unit 101, the expected voltage value corresponding to its expected operating frequency, that is, the suitable voltage value for supporting the power-consuming unit 101 to work at the expected operating frequency, It is also the voltage that the power consumption unit 101 expects to access. Therefore, the performance management unit 102 connected to the power consumption unit 101 can send the expected voltage value as the power consumption unit 101 to the power consumption management unit 105 for the power consumption management unit 105 Make voltage regulation decisions.

It can be understood that, in the embodiment of the present application, the power consumption management unit 105 may receive the expected voltage values of different power consumption units 101 belonging to the same voltage domain, and use the maximum voltage value among them as the voltage value to be regulated for the voltage domain. The voltage value is indicated to the power management unit 103, and the power management unit 103 can adjust the working voltage to the maximum voltage value.

In the embodiment of the present application, each performance management unit 102 is also used to control the power consumption unit 101 connected to it to correspond to work at the desired operating frequency.

In the embodiment of the present application, each performance management unit 102 is also configured to be higher than the current operating frequency when the expected working frequency corresponding to the connected power unit 101 is higher than the current working frequency, and the working voltage reaches the corresponding to the connected power unit 101 In the case of a desired voltage value, control the power consumption unit 101 connected to it to work at the corresponding desired operating frequency.

It should be noted that, in the embodiment of the present application, if the expected operating frequency corresponding to the electric unit 101 is lower than the current operating frequency, the connected performance management unit 102 may directly control the electric unit 101 to work at the expected operating frequency. If the expected operating frequency corresponding to the electric unit 101 is higher than the current operating frequency, the connected performance management unit 102 needs to wait for the operating voltage to reach the expected voltage value corresponding to the electric unit 101, and then control the electric unit 101 to the corresponding Expected operating frequency to work.

In the embodiment of the present application, the power management unit 103 is further configured to send a feedback signal indicating the completion of voltage adjustment to the power consumption management unit 105 after adjusting the working voltage to the maximum voltage value;

The power management unit 105 is further configured to send the maximum voltage value to each performance management unit 102 in the case of receiving the feedback signal.

It should be noted that, in the embodiment of the present application, two-way control and feedback is maintained between the power management unit 103 and the power management unit 105, the power management unit 105 can instruct the power management unit 103 to adjust the voltage, and the power management unit 103 may send a feedback signal to the power management unit 105 after the voltage adjustment is completed. The power consumption management unit 105 can know that the working voltage provided by the power management unit 103 has been adjusted to the maximum voltage value according to the feedback signal, and send the adjusted voltage value, that is, the aforementioned maximum voltage value, to the performance management unit 102 connected to each power consumption unit 101 , so that each performance management unit 102 can know the size of the working voltage.

In the embodiment of the present application, before the power management unit 105 sends the maximum voltage value to the power management unit 103, it is also used to send a cancel to each performance management unit 102 when the operating voltage exceeds the maximum voltage value. instruction;

Each performance management unit 102 is also used to control the power consumption unit 101 connected to it to work at the corresponding historical operating frequency according to the cancel instruction; the corresponding historical operating frequency of each power consumption unit 101 is to work at the corresponding target operating frequency previously used operating frequency.

It should be noted that, in the embodiment of this application, if the maximum voltage value is less than the operating voltage, the process of actually adjusting the operating voltage to the maximum voltage value is step-down. In this case, considering the existing The power consumption unit 101 has been controlled to work at the corresponding target operating frequency according to the operating voltage. Therefore, it is necessary to cancel this operation before stepping down. After the cancellation takes effect, the power management unit 105 will notify the power management unit 103 to proceed. Buck control. Wherein, the power management unit 105 may wait for a preset period of time after sending the cancel instruction, and then send the maximum voltage value to the power management unit 103, so as to ensure that the cancellation takes effect.
