Please refer to fig. 1a, which is a schematic diagram illustrating a method for controlling a terminal according to an embodiment of the present application. An Application Processor (APPS) is a very large scale integrated circuit (lsi) which extends audio and video functions and a dedicated interface on the basis of a Central Processing Unit (CPU), an Advanced Digital Signal Processor (ADSP) is a coprocessor, a display screen is controlled by the APPS, an optical transmitter of a proximity sensor is controlled by the ADSP, the APPS sends the working state of the display screen to the ADSP in the form of a level Signal through a first General-purpose pin (GPIO), and the ADSP sends the working state of the optical transmitter of the proximity sensor to the APPS in the form of a level Signal through a second GPIO.
Please refer to fig. 1b, which is an interaction diagram of a control method of a terminal according to an embodiment of the present application. And the application processor and the coprocessor are interacted through GPIO (general purpose input/output), and the switching between the process display screen and the light emitter of the proximity sensor is controlled.
Please refer to fig. 1c, which is a first flowchart of a terminal control method according to an embodiment of the present disclosure. The method may comprise the steps of:
s101, when the display screen needs to be switched from a screen-off state to a screen-on state, the application processor sends a first level signal to the coprocessor through the first GPIO general pin.
Generally, a processor is a final execution unit for interpreting computer instructions and processing data in computer software, and a plurality of processors may be provided in a terminal device, for example: a primary controlling application processor and a secondary controlling co-processor. The display screen refers to input/output equipment of terminal equipment, is a display tool which displays a certain electronic file on a screen through specific transmission equipment and reflects the electronic file to human eyes, and in the embodiment of the application, the display screen refers to a touch display screen which can replace a mechanical button and is controlled through a tactile feedback system on the screen, for example: infrared display screen, resistance-type display screen and capacitive display screen etc.. The screen-off state and the screen-on state refer to two working states of the display screen, and the display screen is always switched between the two working states. The GPIO is a general-purpose pin used to connect different external devices or circuits, and the processor can control the hardware by sending signals through the GPIO. A coprocessor refers to a processor that is used to work with an auxiliary application processor, such as: an application processor for controlling terminal operation and a coprocessor for controlling transmission information. The first level signal is that after the display screen is switched to the lighting state, the application processor sends a high level signal to the first GPIO, so that the first GPIO level signal is changed into high level.
S102, the application processor receives the second level signal from the coprocessor through a second GPIO.
Generally, the application processor determines a level signal on the GPIO by reading a register corresponding to the second GPIO, and the level signal is a low level signal sent by the coprocessor and written into a relevant register to control the level change on the GPIO.
S103, the application processor responds to the second level signal to switch the display screen to be in a bright screen state.
Generally, the application processor receives the second low level signal sent by the coprocessor, and determines whether a preset interrupt mode condition is met, for example: rising edge, falling edge, double edge, high level trigger and low level trigger. If yes, the application processor executes the recovery interrupt program and lights the display screen.
According to the above, when the display screen needs to be switched from the screen-off state to the screen-on state, the application processor sends the first level signal to the coprocessor through the first GPIO general pin. The application processor receives the second level signal from the coprocessor through a second GPIO. The application processor switches the display screen to a bright screen state in response to the second level signal. The application processor controls the working state of the display screen in an interrupt mode, so that the problem of overlarge delay caused by interaction between different processor bottom layers in the related technology is solved, the delay of terminal switching is reduced, and the endurance time is prolonged.
Referring to fig. 2, a second flow chart of a terminal control method is provided in the embodiment of the present application. The method may comprise the steps of:
s201, the coprocessor receives a first level signal from the application processor.
Typically, the coprocessor determines that the GPIO is high by reading the second GPIO related register, which is sent by the application processor, and writing to the second GPIO related register to indicate the second GPIO level change.
And S202, turning off a light emitter of the proximity sensor in response to the first level signal.
Generally, after the coprocessor receives the first low level signal, if it is determined that a preset interrupt mode condition is satisfied, the coprocessor executes a related configuration to turn off the light emitter of the proximity sensor.
And S203, sending a second level signal to the application processor.
Typically, the coprocessor changes the GPIO up level by writing a second low level signal to a second GPIO related register, and the application processor may receive the second low level signal from the coprocessor by reading the second GPIO related register.
As can be seen from the above, the coprocessor receives a first level signal from the application processor, turns off the light emitter of the proximity sensor in response to the first level signal, and sends a second level signal to the application processor. The coprocessor controls the working state of the light emitter in an interrupt mode, the problem of overlarge delay caused by interaction between different processor bottom layers in the related technology is solved, the delay of terminal switching is reduced, and the endurance time is prolonged.
Referring to fig. 3, a third flowchart of a method for controlling a terminal is provided in an embodiment of the present application. The method may comprise the steps of:
s301, sending a first level signal to the coprocessor through the first GPIO general pin.
Generally, an application processor sends a first high-level signal to a coprocessor through a first GPIO, firstly sets the GPIO to be in an input state, sends the first high-level signal to be written into a register related to the first GPIO, controls the first GPIO to be changed from a low level to a high level, and the coprocessor receives the first high-level signal by reading the register related to the first GPIO.
S302, receiving the second level signal from the coprocessor.
Generally, after the coprocessor indicates that the proximity sensor is turned off, the coprocessor sends a second low-level signal to the application processor through the second GPIO, and the application processor receives the second low-level signal through the second GPIO.
S303, receiving an interrupt recovery command.
In general, the interrupt recovery instruction switches the device from the interrupt state to the recovery state, for example: and the application processor receives the interrupt recovery instruction to switch the display screen from the screen-off state to the lighting state. The application processor receives a second low level signal sent by the second GPIO, and judges whether the level change of the second GPIO meets a preset interrupt mode, for example: and the application processor detects that the second GPIO is changed from high level to low level, the preset falling edge of the application processor triggers an interrupt mode, and an interrupt instruction is sent to control the display screen to be off and interrupted.
And S304, reading the running state data saved in the stack in response to the interrupt recovery instruction.
Generally, an interrupt refers to that when some unexpected situations occur in the running process of a computer and a host needs to intervene, the machine can automatically stop a running program and transfer the running program into a program for processing a new situation, and after the processing is finished, the original suspended program is returned to continue running. When the application processor is in interrupt, it automatically obtains the entry address of the interrupt service subprogram, executes the interrupt service subprogram, and reads the data stored in the stack, for example: code segment register (CS), Instruction Pointer register (IP), and Instruction Pointer register (32-bit) (EIP).
S305, after the register corresponding to the display screen is subjected to numerical value recovery based on the running state data, the display screen is switched to a bright screen state.
Generally, after reading the running state data, the application processor writes the running state data into a corresponding register of the display screen, and executes a program for lighting the display screen based on the data, so as to switch the display screen to a screen-lighting state.
S306, receiving an interrupt request signal.
Generally, the interrupt request signal is an interrupt request signal that the application processor determines whether the interrupt mode satisfies a preset condition, and if so, the application processor sends an interrupt request signal to the display screen to instruct the display screen to interrupt, for example: and the interrupt mode is GPIO falling edge interrupt, the interrupt condition is determined to be met, and the application processor sends an interrupt request signal. When one interrupt source needs the processor to perform interrupt service for the interrupt source, an interrupt request signal is output, an interrupt request trigger of the interrupt control system is set, and the application processor is requested to be interrupted. In the embodiment of the present application, the terminal controls to switch the display screen from the lighting state to the screen-off state through the displacement sensor, for example: when a user takes out the mobile phone and approaches to ears, the displacement sensor detects that the displacement form of the mobile phone meets a preset displacement condition, the coprocessor sends a level signal to the GPIO, the application processor detects that the level change of the GPIO is falling edge interrupt trigger, and the application processor sends an interrupt request signal.
S307, responding to the interrupt request signal, and pushing the running state data of the display screen into a stack for saving.
Generally, after receiving the interrupt request signal, the application processor pushes the current operating state data in the register related to the second GPIO to the stack, so that the application processor can return to the original interrupted program for execution after the interrupt processing is completed, that is, the interrupt is resumed.
And S308, sending a third level signal to the coprocessor through the first GPIO general pin.
Generally, after the display screen is switched from the bright screen state to the off screen state, the display screen still needs to wait for a certain preset time, because the display screen is off and is lighted and also consumes a certain time, for example: the screen-off time of the display screen is 10 milliseconds, the screen-on time is 8 milliseconds, and the co-processor cannot immediately turn on the light emitter of the proximity sensor. And then the application processor sends a third low-level signal to the coprocessor through the first GPIO.
And S309, receiving a fourth level signal from the coprocessor through a second GPIO.
Generally, after receiving the third low level signal, the coprocessor turns on the light emitter of the proximity sensor, and sends a fourth high level signal to the application processor through the second GPIO.
As can be seen from the above, a first GPIO general pin is used to send a first level signal to a coprocessor, receive a second level signal from the coprocessor, receive an interrupt recovery instruction, read running state data stored in a stack in response to the interrupt recovery instruction, perform numerical value recovery on a register corresponding to a display screen based on the running state data, switch the display screen to a bright screen state, receive an interrupt request signal, press the running state data of the display screen into the stack for storage in response to the interrupt request signal, send a third level signal to the coprocessor via the first GPIO general pin, and receive a fourth level signal from the coprocessor via a second GPIO. The application processor controls the working state of the display screen in an interrupt mode, so that the problem of overlarge delay caused by interaction between different processor bottom layers in the related technology is solved, the delay of terminal switching is reduced, and the endurance time is prolonged.
Please refer to fig. 4, which is a fourth flowchart illustrating a control method of a terminal according to an embodiment of the present application. The method may comprise the steps of:
s401, the coprocessor receives a first level signal from the application processor.
Typically, the coprocessor determines by reading a first GPIO related register, a first high signal written into the first GPIO related register by the application processor.
And S402, turning off a light emitter of the proximity sensor in response to the first level signal.
In general, a proximity sensor refers to a detection device for measuring a distance between objects, generally with a light emitter, which determines the distance by optical principles, such as: infrared laser emitters and ultraviolet light emitters, etc. The coprocessor detects a first GPIO level change, for example: detecting that the level change is falling edge interrupt trigger, determining that a preset interrupt trigger condition is met, receiving an interrupt instruction request signal, responding to the interrupt request signal, pushing the running state data of the light emitter of the proximity sensor into a stack for storage, and closing the light emitter of the proximity sensor.
And S403, sending a second level signal to the application processor.
Generally, after the co-processor turns off the light emitter of the proximity sensor, the co-processor sends a second low level signal to the application processor, and the application processor determines the working state of the display screen according to the second low level signal.
S404, the coprocessor receives a third level signal from the application processor.
Typically, the coprocessor determines the third low level signal by reading the first GPIO related register, wherein the third low level signal is changed by the application processor writing into the first GPIO related register.
And S405, responding to the third level signal to turn on a light emitter of the proximity sensor.
Typically, the coprocessor detects a first GPIO level change, such as: detecting that the change mode is rising edge interrupt triggering, determining that preset interrupt triggering conditions are not met, receiving an interrupt recovery instruction, responding to the interrupt recovery instruction, reading operation state data of the light emitter of the proximity sensor, stored in a stack, and turning on the light emitter of the proximity sensor after the display screen is completely turned off for a long time.
And S406, sending a fourth level signal to the application processor.
Generally, after the co-processor turns on the light emitter of the proximity sensor, it sends a fourth high level signal to the application processor, and the application processor can determine the working state of the display screen according to the level signal.
As can be seen from the above, the coprocessor receives a first level signal from the application processor, turns off the light emitter of the proximity sensor in response to the first level signal, and sends a second level signal to the application processor, and the coprocessor receives a third level signal from the application processor, turns on the light emitter of the proximity sensor in response to the third level signal, and sends a fourth level signal to the application processor. The coprocessor controls the working state of the light emitter in an interrupt mode, the problem of overlarge delay caused by interaction between different processor bottom layers in the related technology is solved, the delay of terminal switching is reduced, and the endurance time is prolonged.
