Detailed Description

All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The signal processing method, the signal processing device and the mobile device provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
The embodiment of the application firstly provides a signal processing method, which can be applied to mobile devices such as mobile phones, tablet computers, notebook computers, wearable intelligent devices (such as intelligent watches), augmented reality (augmented reality, AR)/Virtual Reality (VR) devices, vehicle-mounted devices and the like which can communicate by adopting an MIPI interface, and the embodiment of the application is not limited in any way.
The MIPI interface may be employed between circuit elements in a mobile device to communicate with peripherals. The two circuit elements communicating through the MIPI interface may be referred to as a first integrated circuit unit (INTEGRATED CIRCUIT, IC), a second integrated circuit unit, respectively. As shown in fig. 1 (a), the mobile device 100 includes therein a first integrated circuit unit 10 and a second integrated circuit unit 20. The first integrated circuit unit 10 and the second integrated circuit unit 20 each have at least one MIPI interface, interface 101 and interface 201, respectively. The interface 101 on the first integrated circuit unit 10 is connected with the interface 201 of the second integrated circuit unit 20, and data transmission and reception are realized through the connected MIPI interface.
By way of example, the first integrated circuit unit or the second integrated circuit unit that communicates using the MIPI interface may be a Central Processing Unit (CPU), a stand-alone display chip, an image processing chip, a display screen, or the like, which is not particularly limited in this embodiment. In an actual application scenario, as shown in fig. 2, the mobile device 100 may specifically include a processor (CPU) 21, a camera 22, a camera 23, a stand-alone display card 24, and a display screen 25. The independent graphics card 24 is an IC chip added to the mobile device for image enhancement or framing, simply referred to as a single-display IC. The CPU 21 can exchange data with the cameras 22 and 23 through CSI interfaces (CAMERA SERIAL INTERFACE, CSI) for the cameras in MIPI, and can exchange data with the unique IC 24 and the display screen 25 through DSI interfaces (DISPLAY SERIAL INTERFACE, DSI) for the display modules in MIPI. The single-display IC 24 can be used for image enhancement and frame insertion, so that the dynamic range of video image quality is improved, the image quality is enabled to be inserted from original 60fps to 120fps, and the effects of night scene photographing, clearer video recording and the like are achieved. For example, the first integrated circuit unit may be the CPU 21, and the second integrated circuit unit may be the display screen 25, so that the CPU 21 may send an instruction through its MIPI interface connected to the display screen 25, communicate with the display screen 25, and control the display screen to display.
When the mobile device is to be lit, the CPU 21 may send a signal to the unique IC 24 via the MIPI interface, and the unique IC 24 may trigger the display 25 to be lit. After the MIPI signal sent from the CPU 21 is attenuated by the loss of the trace and the unique display IC 24, if the amplitude is smaller than the amplitude standard required by the display screen, the display screen 25 cannot display normally.
In the embodiment of the present application, an integrated circuit unit/chip may be added to the mobile device, and the integrated circuit unit may be referred to as an enhanced circuit unit, an enhanced IC, an enhanced chip, or the like, and the embodiment is not limited thereto. As shown in fig. 1 (b), a first integrated circuit unit 10, a second integrated circuit unit 20, and an enhanced circuit unit 30 may be included in a mobile device 200, and the enhanced circuit unit 30 may perform a signal processing method in an embodiment of the present application. For example, an enhancing circuit unit 30 may be added between the unique display IC 24 and the display screen 25 to enhance the MIPI signal between the unique display IC and the display screen, so as to avoid the problem that the display screen cannot display normally due to signal attenuation.
Based on this, the mobile device provided in the embodiment of the present application may include at least three integrated circuit units, as shown in fig. 1 (b). The first integrated circuit unit 10 and the second integrated circuit unit 20 each include at least one MIPI interface, and are connected to different MIPI interfaces of the enhancement circuit unit 30 (hereinafter referred to as enhancement IC) through MIPI interfaces. The enhanced IC includes at least two MIPI interfaces, such as interface 301 and sum interface 302. Wherein interface 301 interfaces with interface 101 in first integrated circuit unit 10 and interface 302 interfaces with interface 202 in second integrated circuit unit 20. The enhancement circuit unit 30 is operative to implement the signal processing method provided in this embodiment.
Fig. 3 shows a flowchart of a signal processing method according to an embodiment of the present application. As shown in fig. 3, the signal processing method includes the steps of:
And 10, receiving a first signal sent by a first integrated circuit unit, and determining the minimum input voltage when the target sequence is read from the first signal, wherein the first signal is a signal of a mobile industry processor interface MIPI.
The first integrated circuit unit may be, for example, a CPU, a unique IC, or the like. The first integrated circuit unit includes an MIPI interface therein, the MIPI interface being coupled to the boost IC, and the first signal transmitted by the first integrated circuit unit is received by the boost IC via the MIPI interface. The first signal is a signal generated in a specific sequence for calibrating the voltage of the boost IC. The specific sequence is used as a target sequence, a target sequence such as 010101 can be preset, and when the second integrated circuit unit needs to be triggered, the first integrated circuit unit can generate a corresponding electric signal, namely a first signal, according to the target sequence and send the first signal out through the MIPI interface.
The first signal may be, for example, a signal transmitted by the first integrated circuit unit at a highest frequency in the frequency range of the MIPI. The higher the frequency of the signal, the greater the attenuation, and in the case where the frequency of the first signal is the highest frequency, the minimum input voltage to the boost IC may be determined, thereby ensuring that the boost IC is able to receive any MIPI signal of the first integrated circuit unit.
After receiving the first signal through the MIPI interface, the enhancement IC reads the sequence of the first signal and then detects whether the read sequence is a target sequence. If the read sequence is the target sequence, the enhancement IC marks the input voltage at that time as the minimum input voltage. The first integrated circuit unit, the enhancement IC, and the second integrated circuit unit are initialized by powering up according to a default configuration, that is, the input voltage and the output voltage of the enhancement IC may be default values, for example, 1V, which is not particularly limited in this embodiment.
If the correct target sequence cannot be read from the first signal at the default input voltage, the boost IC may increase the input voltage, e.g., by 50mV, 100mV, etc., with each increase detecting the sequence of the first signal until the correct target sequence can be read. The input voltage at the time when the target sequence of the first signal is read is determined as the minimum input voltage. Determining the input voltage at the correct sequence of the MIPI signals read to the first integrated circuit unit as the minimum input voltage of the boost IC ensures that it is able to match the MIPI signal at the highest voltage of the first integrated circuit unit, thereby ensuring that the MIPI signal of the first integrated circuit unit can be correctly received subsequently.
For example, the boost IC may obtain the amplitude of the first signal when the first signal is received, and increase the input voltage based on the amplitude of the first signal. For example, the input voltage of the boost IC may be increased by K times the amplitude of the first signal, or a specific value may be added thereto, which may be empirically set. After increasing the input voltage of the boost IC on the basis of the amplitude of the first signal, the sequence of the first signal may be detected again, and if the correct target sequence is not yet read after increasing the input voltage, a step, i.e. a first step, is determined, based on which the increase of the input voltage is continued. The first step may be a value of 10mV, 20mV, 30mV, or the like, which is not limited in this embodiment. The boost IC may cyclically increase the input voltage on the basis of the first step, detect a sequence of first signals each time the input voltage is increased until the correct target sequence is read, and then take the input voltage at that time as the minimum input voltage of the boost IC.
Fig. 4 shows a flow chart for determining a minimum input voltage. The boost IC may determine the minimum input voltage after receiving the first signal according to the procedure shown in fig. 4. Specifically, in step 31, the amplitude a of the first signal is detected. In step 32, it is determined whether the amplitude A is within a reference voltage range, typically a reference voltage range of 40mV to 1.2V for MIPI. If the amplitude a is within the MIPI reference voltage range, step 33 is performed. The boost IC may ignore the first signal if amplitude a is not within the MIPI reference voltage range, awaiting the next receipt. That is, the boost IC may determine whether amplitude A is greater than or equal to 40mV, if amplitude A is greater than or equal to 40mV, then the first signal meets the MIPI interface criteria. Then, in step 33, the input voltage Vin is increased according to the amplitude a. The input voltage to the boost IC may be increased by, for example, 100mV based on amplitude a, with the increased input voltage vin=a+100 mV. In addition, the input voltage may be increased in other manners, for example, 10mV, 50mV, etc. based on the amplitude a, which is not particularly limited in this embodiment.
Next, in step 34, it is detected whether the target sequence is read. If the target sequence is not read after increasing the voltage, step 35 is performed, and if the target sequence is read, step 36 is performed. In step 36, the input voltage Vin at this time is set to the minimum input voltage. That is, the input voltage of the boost IC in normal operation needs to be greater than or equal to the minimum input voltage. Referring to fig. 4, in step 35, the input voltage is increased, vin=vin+20mv, and then the process proceeds to step 34. The result of the first step is the increased input voltage Vin based on the current input voltage Vin. The first step may be 20mV, i.e. the input voltage vin=vin+20 mV after increasing. After increasing the input voltage Vin in step 35, the process goes to step 34 to loop until the target sequence is read. The final input voltage Vin is determined as the minimum input voltage of the boost IC.
Next, step 20, in case of a minimum input voltage, sends a second signal to the second integrated circuit unit based on the target sequence and detects the amplitude of the second signal received by the second integrated circuit unit.
The enhancement IC may regenerate the signal of the corresponding waveform, i.e., the second signal, according to the target sequence and send it to the second integrated circuit unit. The enhancement IC is also connected to the second integrated circuit unit via the MIPI interface, so that the second signal is also a signal sent via the MIPI interface. A feedback circuit may be provided between the enhancement IC and the second integrated circuit unit, through which feedback circuit the amplitude of the second signal received by the second integrated circuit unit is detected.
And 30, determining the minimum output voltage according to the amplitude of the second signal received by the second integrated circuit unit.
The amplitude of the second signal needs to match the standard amplitude of the second integrated circuit unit, and if the amplitude of the second signal is smaller than the standard amplitude of the second integrated circuit unit, the second signal cannot be read correctly by the second integrated circuit unit. The output voltage of the second integrated circuit unit may be a default value, e.g. 1V, etc., at power-up initialization. The boost IC may determine whether the amplitude of the second signal detected by the feedback is less than the standard amplitude of the second integrated circuit unit, and increase the output voltage in case it is determined that the amplitude of the second signal is less than the standard amplitude of the second integrated circuit unit. If the amplitude of the second signal is not less than the standard amplitude of the second signal, the current output voltage is determined as the minimum output voltage. The voltage which can be received by the second integrated circuit unit is determined to be the minimum output voltage, so that the MIPI signal sent by the enhancement IC can meet the requirement of the second integrated circuit unit, and the second integrated circuit unit can be ensured to normally receive the MIPI signal.
For example, the boost IC may be stepped up based on a predetermined step as the output voltage is increased. This step serves as the second step. Specifically, as shown in fig. 5, the process of increasing the output voltage includes:
Step 41, generating a second signal of the target sequence. The enhancement IC may generate a second signal according to the target sequence at the default output voltage Vout, where the generated second signal is sent out through the MIPI interface with the second integrated circuit unit, and reaches the second integrated circuit unit through attenuation of the routing loss. And 42, acquiring the amplitude C of a second signal of the second integrated circuit unit through a feedback circuit. Step 43, calculating the difference Z between the amplitude C and the standard amplitude S of the second integrated circuit unit, i.e. z=c-S. Step 44, judging whether Z is smaller than 0, if Z is larger than or equal to 0, executing step 46, and if Z is smaller than 0, executing step 45, and entering a loop, as shown in FIG. 5. Step 45, adjusting the output voltage in such a way that vout=vout+z×k. Wherein K is the second step, and ZxK is the current increasing amplitude of the output voltage Vout, and ZxK is increased on the basis of the current output voltage Vout, so as to obtain the regulated output voltage Vout. Increasing the present output voltage by a factor of the second step may linearly increase the output voltage such that the output voltage is in a linear relationship with the second signal, thereby enhancing the second signal. Then, the process goes to step 41 again, the second signal is outputted again with the increased output voltage, and the loop is sequentially repeated until the amplitude C of the second signal is greater than or equal to the standard amplitude S in step 44, and the loop is exited. In step 46, the output voltage Vout is recorded as the minimum output voltage. And the final output voltage is the minimum output voltage after the cycle is finished. After determining the minimum output voltage, the output voltage of the boost IC may be set to be greater than or greater than the minimum output voltage, that is, the output voltage of the boost IC under normal operation may take on a value in a range greater than or equal to the minimum output voltage.
Step 40, receiving the MIPI signal sent by the first integrated circuit unit under the condition of the minimum input voltage and the minimum output voltage, and sending the MIPI signal to the second integrated circuit unit again.
The input voltage of the enhancement IC needs to be above the minimum input voltage, the output voltage needs to be above the minimum output voltage, and the enhancement IC can be reset according to the range and then work normally. The enhancement IC can receive the MIPI signal of the first integrated circuit unit and transmit the enhanced MIPI signal to the second integrated circuit unit, so that the MIPI signal is ensured to be normally transmitted between the first integrated circuit unit and the second integrated circuit unit, and the problem of signal attenuation is avoided.
Next, the signal processing method and the mobile device of the present embodiment will be described using the first integrated circuit unit as a single-display IC and the second integrated circuit unit as a screen. Fig. 6 shows a circuit schematic of the mobile device. As shown in fig. 6, the mobile device includes a unique IC 51, an enhanced IC 52, and a display screen LCM 53. Wherein the enhanced IC 52 includes two sets of MIPI interfaces. The MIPI interface consists of a set of differential clocks and 1 to 3 sets of differential data, the number of sets of differential data employed being determined based on the amount of data transferred. Taking a group of differential data as an example, the first MIPI interface, which is a group of MIPI interfaces of the enhanced IC, includes a pin a1, a pin a2, a pin a3, and a pin a4, which are respectively connected to pins of the MIPI interface in the unique IC 51. The pins a1 and a2 are a group of differential data. The other group of MIPI interfaces, namely the second MIPI interface, comprises a pin b1, a pin b2, a pin b3 and a pin b4 which are respectively connected with pins of the MIPI interface 531 in the display screen LCM 53. Wherein, the pins b1 and b2 are a group of differential data. The MIPI signal is a differential signal, from which the amplitude of the signal can be determined.
Further, the enhancement IC 52 includes a detection circuit 54 and a feedback circuit 55. The detection circuit 54 interfaces with a set of differential data pins in the MIPI interface of the unique IC for detecting the amplitude of the MIPI signal. The feedback circuit 55 interfaces with a set of differential data pins in the MIPI interface of the display screen for detecting the amplitude of the MIPI signal at the display screen LCM 53.
For example, when the CPU receives an event that a key is touched to illuminate the screen in a standby or power-off condition, the CPU may send a calibration signal, i.e., a first signal, to the unique IC 51 at the highest frequency used on the MIPI interface. The unique IC 51 sends the first signal to the boost IC 52 for receipt by the MIPI interface 521 of the boost IC 52, while the boost IC detects the amplitude of the first signal through the detection circuit 54. The minimum input voltage is determined based on the amplitude of the first signal. The enhancement IC 52 then regenerates the second signal to send out through MIPI interface 522, through trace loss (simply referred to as line loss) to LCM 53. At the same time, boost IC 52 detects the amplitude of the second signal via feedback circuit 55 in front of LCM 53, and determines the minimum output voltage based on the amplitude of the second signal. The first signal is identical to the sequence of the second signal. After determining the minimum input voltage and the minimum output voltage, the CPU may send a command for lighting the screen to the single-display IC 51, so that the single-display IC 51 controls the screen LCM 53 to light the screen, and perform normal display.
It should be understood that, in the above embodiment, the signal processing method is performed by setting the enhanced IC before the single-display IC and the screen, and the signal processing method provided in the present embodiment may also be applied to a CPU and a camera, a CPU and a single-display IC, or a CPU and other peripheral devices such as a CPU and a screen, which is not limited in any way.
Further, in the signal processing method provided by the embodiment of the present application, the execution body may be a signal processing device.
