[0021] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in an "or" relationship.

[0023] The signal processing method, signal processing device and mobile device provided by the embodiments of the present application will be described in detail below in conjunction with the drawings, specific embodiments and application scenarios.

[0024] The embodiments of the present application first provide a signal processing method, which can be applied to mobile devices that can communicate using MIPI interfaces, such as mobile phones, tablet computers, notebook computers, wearable smart devices (such as smart watches), augmented reality (AR) / virtual reality (VR) devices, and vehicle-mounted devices, etc. The embodiments of the present application do not make any limitation on this.

[0025] Circuit elements in a mobile device can communicate with peripherals using MIPI interfaces. Two circuit elements that communicate through MIPI interfaces can be respectively referred to as a first integrated circuit unit (IC) and a second integrated circuit unit. For example, Figure 1 As shown in (a), the mobile device 100 includes 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, which are interface 101 and interface 201, respectively. The interface 101 on the first integrated circuit unit 10 interfaces with the interface 201 of the second integrated circuit unit 20, and data transmission and reception are achieved through the interfaced MIPI interfaces.

[0026] For example, the first integrated circuit unit or the second integrated circuit unit that communicates using the MIPI interface can be a central processing unit (CPU), an independent display chip, an image processing chip, a display screen, etc., and the embodiments do not make special limitations on this. In actual application scenarios, for example, Figure 2As shown, the mobile device 100 can specifically include a processor (CPU) 21, a camera 22, a camera 23, a discrete graphics card 24, and a display screen 25. The discrete graphics card 24 is an IC chip added to the mobile device for image enhancement or frame interpolation, which is referred to as a discrete IC. The CPU 21 can exchange data with the camera 22 and the camera 23 through a CSI (Camera Serial Interface) interface for the camera in MIPI; and can exchange data with the discrete IC 24 and the display screen 25 through a DSI (Display Serial Interface) interface for the display module in MIPI. The discrete IC 24 can be used for image enhancement and frame interpolation, to improve the dynamic range of video quality, so that the quality is interpolated from the original 60fps to 120fps, to achieve clearer effects such as night scene shooting and video recording. For example, the first integrated circuit unit can be the CPU 21, and the second integrated circuit unit can be the display screen 25. The CPU 21 can send instructions to the display screen 25 through the MIPI interface connected to the display screen 25, to communicate with the display screen 25 and control the display screen to display.

[0027] When the mobile device needs to turn on the screen, the CPU 21 can send a signal to the discrete IC 24 through the MIPI interface, and the discrete IC 24 can trigger the display screen 25 to turn on the screen. After the MIPI signal from the CPU 21 is attenuated by the wiring and the discrete IC 24, if the amplitude is less than the amplitude standard required by the display screen, the display screen 25 cannot display normally.

[0028] In the above mobile device, an integrated circuit unit / chip can be added in the embodiment of the present application. The integrated circuit unit can be referred to as an enhancement circuit unit, an enhancement IC, an enhancement chip, etc., and the embodiment of the present application is not limited thereto. As shown in FIG. 1, Figure 1 As shown in (b) of FIG. 1, the mobile device 200 can include a first integrated circuit unit 10, a second integrated circuit unit 20, and an enhancement circuit unit 30. The enhancement circuit unit 30 can perform the signal processing method in the embodiment of the present application. For example, an enhancement circuit unit 30 can be added between the discrete IC 24 and the display screen 25, to enhance the MIPI signal between the discrete IC and the display screen, to avoid the problem that the signal attenuation causes the display screen to be unable to display normally.

[0029] Based on this, the mobile device provided in the embodiment of the present application can include at least three integrated circuit units, as shown in FIG. 1, Figure 1As shown in (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 enhanced circuit unit 30 (hereinafter referred to as an enhanced IC) through the MIPI interfaces. The enhanced IC includes at least two MIPI interfaces, such as interface 301 and interface 302. The interface 301 is connected to the interface 101 in the first integrated circuit unit 10, and the interface 302 is connected to the interface 202 in the second integrated circuit unit 20. The enhanced circuit unit 30 can implement the signal processing method provided in the embodiment when it is working.

[0030] Figure 3 A flowchart of the signal processing method provided in the embodiment of the application is shown. As shown in (a), the signal processing method includes the following steps: Figure 3

[0031] Step 10: receiving a first signal sent by the first integrated circuit unit, and determining a minimum input voltage when a target sequence is read from the first signal, wherein the first signal is a signal of a Mobile Industry Processor Interface (MIPI).

[0032] The first integrated circuit unit can be a CPU, a discrete graphics IC, or the like. The first integrated circuit unit includes a MIPI interface connected to the enhanced IC, and the first signal sent by the first integrated circuit unit is received by the enhanced IC through the MIPI interface. The first signal is a signal generated according to a specific sequence, and is used to calibrate the voltage of the enhanced IC. The specific sequence is a target sequence, which can be set in advance, such as 010101, and when the second integrated circuit unit needs to be triggered, the first integrated circuit unit can generate a corresponding electrical signal, i.e., the first signal, according to the target sequence, and send it out through the MIPI interface.

[0033] For example, the first signal can be a signal sent by the first integrated circuit unit at the highest frequency in the frequency range of the MIPI. The higher the frequency of the signal, the greater the attenuation. In the case where the frequency of the first signal is the highest frequency, the minimum input voltage of the enhanced IC can be determined, so as to ensure that the enhanced IC can receive any MIPI signal of the first integrated circuit unit.

[0034] After the enhanced IC receives the first signal through the MIPI interface, the sequence of the first signal is read, and then it is detected whether the read sequence is the target sequence. If the read sequence is the target sequence, the enhanced IC records the input voltage at this time as the minimum input voltage. The first integrated circuit unit, the enhanced IC, and the second integrated circuit unit are powered on and initialized according to a default configuration, that is, the input voltage and the output voltage of the enhanced IC can be default values, such as 1V, and the present embodiment does not specially limit this.

[0035] ​If the correct target sequence cannot be read from the first signal at the default input voltage, the enhanced IC can increase the input voltage, for example, increase the input voltage by 50mV, 100mV, etc., and detect the sequence of the first signal each time the input voltage is increased, until the correct target sequence can be read. The input voltage at which the target sequence of the first signal is read is determined as the minimum input voltage. The input voltage at which the correct sequence of the first integrated circuit unit MIPI signal is read is determined as the minimum input voltage of the enhanced IC, which can ensure that it can match the MIPI signal of the first integrated circuit unit at the highest voltage, so that it can correctly receive the MIPI signal of the first integrated circuit unit subsequently.

[0036] For example, the enhanced IC can obtain the amplitude of the first signal when receiving the first signal, and increase the input voltage based on the amplitude of the first signal. For example, the input voltage of the enhanced IC can be increased to K times the amplitude of the first signal, or a certain value can be added to the amplitude, which can be set empirically. After the input voltage of the enhanced IC is increased based on the amplitude of the first signal, the sequence of the first signal can be detected again. If the correct target sequence is still not read after the input voltage is increased, a step is determined, which is a first step, and the input voltage is continued to be increased based on the first step. The first step can be 10mV, 20mV, 30mV, etc., which is not limited in the embodiment. The enhanced IC can increase the input voltage cyclically based on the first step, and detect the sequence of the first signal each time the input voltage is increased, until the correct target sequence is read. At this time, the input voltage is determined as the minimum input voltage of the enhanced IC.

[0037] Figure 4 A flow chart for determining the minimum input voltage is shown. After the enhanced IC receives the first signal, it can increase the input voltage according to the first step, and detect the sequence of the first signal each time the input voltage is increased, until the correct target sequence is read. At this time, the input voltage is determined as the minimum input voltage of the enhanced IC. Figure 4The flow shown determines the minimum input voltage. 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 the reference voltage range, which is typically 40mV to 1.2V for MIPI. If the amplitude A is within the MIPI reference voltage range, step 33 is performed. If the amplitude A is not within the MIPI reference voltage range, the enhanced IC can ignore the first signal and wait for the next reception. That is, the enhanced IC can determine whether the amplitude A is greater than or equal to 40mV, and if the amplitude A is greater than or equal to 40mV, the first signal is in compliance with the MIPI interface standard. Then, in step 33, the input voltage Vin is increased based on the amplitude A. The input voltage of the enhanced IC can be increased by, for example, 100mV based on the amplitude A, and the increased input voltage Vin = A + 100mV. In addition, the input voltage can be increased in other ways, such as by 10mV, 50mV, etc. based on the amplitude A, and the present embodiment is not limited in this regard.

[0038] Next, in step 34, it is determined whether the target sequence is read. If the target sequence is not read after the voltage is increased, step 35 is performed; if the target sequence is read, step 36 is performed. In step 36, the input voltage Vin at this time is set as the minimum input voltage. That is, the input voltage of the enhanced IC needs to be greater than or equal to the minimum input voltage in normal operation. Referring to Figure 4 In step 35, the input voltage is increased, Vin = Vin + 20mV, and then the process returns to step 34. The first step is 20mV, i.e., the increased input voltage Vin = Vin + 20mV based on the current input voltage Vin. The first step can be 20mV, i.e., the increased input voltage Vin = Vin + 20mV. After the input voltage Vin is increased in step 35, the process returns to step 34 and repeats until the target sequence is read. The final input voltage Vin is determined as the minimum input voltage of the enhanced IC.

[0039] Next, step 20: under the minimum input voltage, a second signal is transmitted to the second integrated circuit unit based on the target sequence, and the amplitude of the second signal received by the second integrated circuit unit is detected.

[0040] The enhanced IC can regenerate a signal corresponding to the waveform of the target sequence, i.e., the second signal, and transmit it to the second integrated circuit unit. The enhanced IC and the second integrated circuit unit are also connected by a MIPI interface, so the second signal is also a signal transmitted by the MIPI interface. A feedback circuit can be provided between the enhanced IC and the second integrated circuit unit, and the amplitude of the second signal received by the second integrated circuit unit is detected through the feedback circuit.

[0041] Step 30: Determine the minimum output voltage according to the amplitude of the second signal received by the second integrated circuit unit.

[0042] 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 less than the standard amplitude of the second integrated circuit unit, it cannot be correctly read by the second integrated circuit unit. When the second integrated circuit unit is powered on and initialized, the output voltage can be a default value, such as 1V, etc. The enhanced IC can 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 in the case where it is determined that the amplitude of the second signal is less than the standard amplitude of the second integrated circuit unit, the output voltage is increased. 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. Determining the voltage that the second integrated circuit unit can receive as the minimum output voltage can ensure that the MIPI signal sent by the enhanced IC can meet the needs of the second integrated circuit unit, and ensure that the second integrated circuit unit normally receives the MIPI signal.

[0043] For example, when the enhanced IC increases the output voltage, it can gradually increase based on a predetermined step. The step serves as a second step. Specifically, the process of increasing the output voltage includes: Figure 5

[0044] Step 41: Generate the second signal of the target sequence. The enhanced IC can generate the second signal according to the target sequence at the default output voltage Vout, and the generated second signal is sent out through the MIPI interface between the enhanced IC and the second integrated circuit unit, and reaches the second integrated circuit unit after attenuation by the loss of the wiring. Step 42: Collect the amplitude C of the second signal of the second integrated circuit unit through the feedback circuit. Step 43: Calculate 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: Determine whether Z is less than 0; if Z is greater than or equal to 0, execute step 46; if Z is less than 0, execute step 45, and enter a loop, as shown in Figure 5 ​Step 45: adjust the output voltage, and the adjustment manner is: Vout = Vout + Z x K. Wherein K is the second step, Z x K is the current output voltage Vout of the increase amplitude, on the basis of the current output voltage Vout, increase Z x K, to get the adjusted output voltage Vout. With the second step as the coefficient to increase the current output voltage, the output voltage can be linearly increased, so that the output voltage is linearly related to the second signal, thereby enhancing the second signal. Then go to step 41 again, output the second signal with the increased output voltage, and cycle in turn until step 44, the amplitude C of the second signal is greater than or equal to the standard amplitude S, and the cycle is exited. In step 46, the output voltage Vout is recorded as the minimum output voltage. When the cycle is ended, the final output voltage is the minimum output voltage. After determining the minimum output voltage, the output voltage of the enhancement IC can be set to be greater than or greater than the minimum output voltage, that is, the output voltage of the enhancement IC under normal working is in the range of greater than or equal to the minimum output voltage.

[0045] Step 40: under the condition of the minimum input voltage and the minimum output voltage, receive the MIPI signal sent by the first integrated circuit unit, and send the MIPI to the second integrated circuit unit again.

[0046] The input voltage of the enhancement IC needs to be above the minimum input voltage, and the output voltage needs to be above the minimum output voltage. According to the range, the enhancement IC can be reconfigured and then normally work. The enhancement IC can receive the MIPI signal of the first integrated circuit unit and send the signal after enhancement to the second integrated circuit unit, thereby ensuring the normal transmission of the MIPI signal between the first integrated circuit unit and the second integrated circuit unit, and avoiding the problem of signal attenuation.

[0047] Next, taking the first integrated circuit unit as the discrete graphics IC and the second integrated circuit unit as the screen as an example, the signal processing method and the mobile device of the embodiment are described. Figure 6 The circuit schematic diagram of the mobile device is shown. As shown in Figure 6As shown, the mobile device includes a discrete display IC 51, an enhanced IC 52, and a display screen LCM 53. The enhanced IC 52 includes two groups of MIPI interfaces. The MIPI interface consists of a group of differential clock and 1 to 3 groups of differential data, and the number of groups of differential data used is determined according to the amount of data transmitted. Taking a group of differential data as an example, the first MIPI interface of the enhanced IC includes pins a1, a2, a3, and a4, which are connected to the pins of the MIPI interface of the discrete display IC 51, respectively. Among them, pins a1 and a2 are a group of differential data. The second MIPI interface includes pins b1, b2, b3, and b4, which are connected to the pins of the MIPI interface 531 of the display screen LCM 53, respectively. Among them, pins b1 and b2 are a group of differential data. The MIPI signal is a differential signal, and the amplitude of the signal can be determined according to a group of differential data.

[0048] In addition, the enhanced IC 52 also includes a detection circuit 54 and a feedback circuit 55. The detection circuit 54 is connected to a group of differential data pins of the MIPI interface of the discrete display IC, for detecting the amplitude of the MIPI signal. The feedback circuit 55 is connected to a group of differential data pins of the MIPI interface of the display screen, for detecting the amplitude of the MIPI signal at the display screen LCM 53.

[0049] For example, when the CPU receives a key trigger screen-on event in the standby or shutdown state, the CPU can send a calibration signal, i.e. a first signal, to the discrete display IC 51 according to the highest frequency used on the MIPI interface. The discrete display IC 51 sends the first signal to the enhanced IC 52, which is received by the MIPI interface 521 of the enhanced IC 52, and the enhanced IC detects the amplitude of the first signal through the detection circuit 54. The minimum input voltage is determined according to the amplitude of the first signal. Then the enhanced IC 52 generates a second signal and sends it out through the MIPI interface 522, which reaches the LCM 53 after passing through the line loss. At the same time, the enhanced IC 52 detects the amplitude of the second signal through the feedback circuit 55 before the LCM 53, and determines the minimum output voltage according to the amplitude of the second signal. The sequence of the first signal and the second signal is the same. After determining the minimum input voltage and the minimum output voltage, the CPU can send a screen-on instruction to the discrete display IC 51, so that the discrete display IC 51 controls the screen LCM 53 to turn on and display normally.

[0050] It should be understood that the above embodiment is an example of setting an enhancement IC in front of a display IC and a screen to perform the signal processing method, and the signal processing method provided in the embodiment can also be applied to a CPU and other peripherals such as a camera, a display IC, or a screen, and the present application does not limit this.

[0051] Further, the signal processing method provided in the embodiment can be executed by a signal processing device. Hereinafter, the signal processing device provided in the embodiment will be described with an example of executing the signal processing method in the signal processing device.

[0052] As shown in Figure 7 The signal processing device 60 provided in the embodiment can include a first receiving module 61, a first sending module 62, a first processing module 63, and a second processing module 64. Specifically, the first receiving module 61 is configured to receive a first signal sent by a first integrated circuit unit, and determine a minimum input voltage when a target sequence is read from the first signal, wherein the first signal is a signal of a Mobile Industry Processor Interface (MIPI). The first sending module 62 is configured to send a second signal to a second integrated circuit unit based on the target sequence under the condition of the minimum input voltage, and detect an amplitude of the second signal received by the second integrated circuit unit. The first processing module 63 is configured to determine a minimum output voltage according to the amplitude of the second signal received by the second integrated circuit unit. The second processing module 64 is configured to receive a MIPI signal sent by the first integrated circuit unit under the condition of the minimum input voltage and the minimum output voltage, and resend the MIPI signal to the second integrated circuit unit.

[0053] The signal processing device provided in the embodiment can adjust the input voltage by receiving the signal of the first integrated circuit unit, and adjust the output voltage by sending the signal to the second integrated circuit unit, so that the input voltage and the output voltage can be matched with the first integrated circuit unit and the second integrated circuit unit respectively, and the correct transmission of the signal can be ensured, and the effectiveness of the signal transmission can be improved. In addition, the amplitude of the signal can be increased by increasing the output voltage, so that abnormal problems caused by loss during the transmission of the signal can be avoided, and the normal work of the second integrated circuit unit can be ensured.

[0054] In an exemplary embodiment, the first receiving module 61 can specifically include a first detection unit configured to receive the first signal, detect whether the target sequence of the first signal is read, and increase the input voltage if the target sequence of the first signal is not read.

[0058] In the example implementation, the third increasing unit is specifically configured to determine a difference between the amplitude of the second signal and the standard amplitude, and increase the output voltage based on the difference.

[0059] In the example implementation, the first signal is a signal transmitted by the first integrated circuit unit based on the highest frequency in a target frequency range, where the target frequency range is a frequency range of MIPI between the first integrated circuit unit and the second integrated circuit unit.
