Description

Direction control application starting method and device, electronic equipment and storage medium

Technical Field

The present application relates to the field of electronic device technologies, and in particular, to a method and an apparatus for starting a direction control application, an electronic device, and a storage medium.

Background

At present, most systems of electronic equipment are based on an Android system, and the Android system is long in starting time, which is usually more than 7 seconds. For safety, the electronic device needs to respond to the direction control signal immediately after cold start to display the current video (video image). If the direction control application is started after the Android system is started, the time for starting the direction control application is more than 7 seconds, and the requirement for immediately responding to the direction control signal cannot be met.

In order to solve the problem, an existing scheme is that after a system is started for the first time, the system enters a sleep mode each time, and the system is waken up from the sleep mode each time, so as to meet the requirement of rapidly displaying videos; by adopting the dormancy mechanism, although the video display time is shortened, the dormancy mechanism can enable the system to stay in the memory for a long time, so that fragmentation of the system memory is increased, the working stability is reduced, and meanwhile, the system can consume extra electric quantity because the system is in the dormancy state for a long time. The other scheme is that a micro-control unit is added, and the micro-control unit is used for rapidly displaying videos; although the micro-control unit can shorten the video display time, it adds extra hardware cost, and needs to modify the hardware architecture, which increases the complexity of hardware and software.

Therefore, how to implement quick start of the direction control application to achieve quick display of a video is a technical problem that needs to be solved urgently by those skilled in the art.

The embodiment of the application provides a method and a device for starting a direction control application, electronic equipment and a storage medium. Any direction control application starting device provided by the embodiment of the application can be integrated in electronic equipment. The electronic device may be various devices that are installed with an operating system and require direction control and direction control image display. The following embodiments are described by taking an example in which the direction control application starting method is applied to a scene of a vehicle-mounted device, the electronic device is a vehicle which is installed with an operating system and can realize direction control and direction control video image display, but the present application is not limited thereto, and the direction control application method of the present application can be applied to any device which is installed with an operating system and can realize direction control and direction control video image display. The system of the electronic equipment can be an android system, an apple system and other systems. The electronic device includes at least two CPU cores (CPU cores) having an interrupt resource.

In the embodiment of the present application, an operating system of an electronic device will be described as an example of an android system.

Please refer to fig. 1, which is a flowchart illustrating a method for starting a direction control application according to an embodiment of the present application. The direction control application starting method is applied to electronic equipment, the electronic equipment comprises at least two CPU cores, and the direction control application starting method comprises the following steps. The directional control application launching method may be understood in particular in conjunction with fig. 5.

101, after receiving the CPU core wake-up instruction, waking up at least two CPU cores.

When the electronic device is in cold Boot, a Boot loader (Boot loader) is loaded from a memory at first, and the Boot loader includes a Boot ROM program and an SBL (second Boot loader) program, where the Boot ROM program is a first section of program that runs after the system is powered on, and the SBL program is a second section of program that runs after the system is powered on. When the system is started to the later stage of the boot loader, namely, the system is started to one stage in the SBL program, the electronic equipment receives the CPU core awakening instruction and awakens at least two CPU cores according to the CPU core awakening instruction. Waking up a CPU core may be understood as waking up all CPU cores in an electronic device; or may be a CPU core that needs to be used when the electronic device is woken up for starting, such as a first CPU core and a second CPU core included in the following.

And 102, after the at least two CPU cores are awakened, loading the bare metal deployment program to a first CPU core, and loading the operating system kernel of the electronic device to a second CPU core, so that the first CPU core starts the bare metal deployment program, and the second CPU core starts the operating system of the electronic device, where the bare metal deployment program includes the first direction control application.

The bare metal deployment program (barefoot program) comprises a first direction control application, and for example, in a vehicle-mounted device scene, the first direction control application can be understood as a first reverse application. It can be simply understood that writing the first direction control application into the barecetal environment allows the first direction control application to run in a CPU core without an operating system, and opening the barecetal program is understood to be opening the first direction control application. kernel is a kernel, is a core of an operating system, provides the most basic functions of the operating system, is the basis of the operation of the operating system, and is responsible for managing processes, memories, device drivers, files and network systems of the system and determining the performance and stability of the system.

The method comprises the steps of presetting a first CPU core used for loading a bare engine deployment program and a second CPU core used for loading an operating system core of the electronic equipment in the CPU cores of the electronic equipment, determining a first CPU core identifier of the first CPU core used for loading the bare engine deployment program and determining a second CPU core identifier of the second CPU core used for loading the operating system core of the electronic equipment.

It is to be understood that the CPU core of the electronic device is divided into a first CPU core and a second CPU core, where the number of the first CPU core is one, and the remaining cores of the electronic device excluding the first CPU core are taken as the second CPU core. For example, the total number of cores in the electronic device is 4, the number of first CPU cores is 1, and the number of second CPU cores is 3; the total number of cores in the electronic device is 8, the number of first CPU cores is 1, and the number of second CPU cores is 7. In some cases, the remaining cores of the electronic device except the first CPU core are used as the second CPU core, and it is understood that not all of the remaining cores are used for loading the operating system kernel of the electronic device and for starting the operating system, and some cores may be reserved for other purposes.

The method comprises the steps of firstly setting a CPU core identifier of a CPU core, then determining a first CPU core identifier of a first CPU core for loading a bare metal deployment program, and determining a second CPU core identifier for loading an operating system kernel of the electronic equipment. In the embodiment of the present application, 4 CPU cores, 1 first CPU core, and 3 second CPU cores are taken as an example for description. The CPU core identifications of the 4 CPU cores are set to be CPU0, CPU1, CPU2, and CPU3, respectively. The second CPU core of the operating system kernel of the electronic device is determined to be loaded as CPU0, CPU1 and CPU2, and the first CPU core of the bare metal deployment program is determined to be loaded as CPU 3.

After the corresponding CPU core identification is determined, correspondingly loading the bare metal deployment program to the first CPU core and loading the operating system kernel of the electronic device to the second CPU core, wherein the steps comprise: loading a bare metal deployment program to a first CPU core according to the first CPU core identifier; and loading the operating system kernel of the electronic equipment to the second CPU core according to the second CPU core identifier.

103, controlling the first CPU core to initialize the associated hardware of the first direction control application after starting the bare metal deployment program.

The related hardware of the direction control application comprises a camera, a camera interface, an image processing unit, a distortion correction unit, a display interface, a display screen and the like of the electronic equipment.

After a system of the electronic device is powered on, the electronic device controls the first CPU core to initialize the associated hardware of the first direction control application after the bare metal deployment program is started.

And 104, controlling the first CPU core to start the first direction control application.

After the initialization of the associated hardware of the first direction control application is completed, the electronic device controls the first CPU core to start the first direction control application.

According to the method, after the CPU core is awakened, the bare computer deployment program is loaded to the first CPU core, and meanwhile, the operating system core of the electronic equipment is loaded to the second CPU core, so that the first CPU core starts the first direction control application, and the second CPU core starts the operating system of the electronic equipment, therefore, the operating system of the electronic equipment is normally started, and the first direction control application is started at the same time, the starting flow and the starting time of the operating system of the electronic equipment are not influenced, the first direction control application can be quickly started, and the direction control signal is quickly responded. On the other hand, it is understood that the bare metal deployment program is an independent application that implements a fast direction control display when the system is in cold boot, and it coexists with the operating system, and uses an independent CPU core in the electronic device, but does not occupy interrupt resources, so the first direction control application can be used no matter which stage the operating system is booted, i.e. after the first direction control application is booted using the first CPU core, the first direction control application is in an executable state, and in the process of booting the operating system of the electronic device using the second CPU core, it is not necessary to detect whether there is a related operation such as a direction control signal, and the boot flow and boot time of the operating system of the electronic device are not affected, and the boot flow of the operating system of the electronic device is not interrupted/interrupted by the direction control signal. In addition, the first direction control application is started by using the first CPU core, namely, the first direction control application is started by using an independent CPU core, so that the additional hardware cost is not increased, and the processing function of the video image can be improved.

Fig. 2 is a flowchart illustrating a method for starting a direction control application in an embodiment of the present application. The direction control application start mode includes the following steps 201 to 207.

And 201, after receiving the CPU core wake-up instruction, waking up at least two CPU cores.

202, after the at least two CPU cores are woken up, loading the bare metal deployment program to a first CPU core, and loading the operating system kernel of the electronic device to a second CPU core, so that the first CPU core starts the bare metal deployment program, and so that the second CPU core starts the operating system of the electronic device, where the bare metal deployment program includes the first direction control application.

And 203, controlling the first CPU core to initialize the associated hardware of the first direction control application after starting the bare metal deployment program.

And 204, controlling the first CPU core to start the first direction control application.

Please refer to the corresponding descriptions in steps 101 to 104 above for steps 201 to 204.

205, when the first CPU core detects the direction control signal and does not receive the start notification sent by the second CPU core that the operating system has been started, control the first direction control application to acquire the video data from the camera through the camera interface.

If in a vehicle-mounted device scene, the first CPU core detects a reverse signal, that is, detects a direction control signal, which means that the electronic device is about to start direction control (such as reversing); in other scenarios, whether a directional control signal is detected is determined by other means. If the starting notification that the operating system is started and sent by the second CPU core is not received, it means that the current operating system of the electronic device is not started yet, and the second direction control application in the operating system cannot be used for direction control, so that the video image is displayed. Therefore, when the first CPU core detects the direction control signal and does not receive the start notification sent by the second CPU core that the operating system has been started, the first direction control application in the first CPU core is controlled to acquire the video data from the camera through the camera interface.

It is understood that, after the operating system is started, the second CPU core sends a start notification that the operating system is started to the first CPU core to notify the first CPU core that the operating system is currently started. The first CPU core and the second CPU core are communicated in an inter-core communication mode.

In the first CPU core, detecting a direction control signal, detecting a start state of an operating system, detecting a hardware state of a camera, an image processing unit, a display unit, and the like may be implemented by a related event, and the first direction control application obtains a state of the corresponding related event by circularly processing the related event, which is described in detail below with reference to fig. 7.

It should be noted that, in the process that the first CPU core is controlling the first direction control application to acquire the video data from the camera through the camera interface, if a start notification sent by the second CPU core that the operating system is started is received, the first direction control application is still controlled to acquire the video data from the camera through the camera interface at this time until the direction control is finished. If the forward gear signal is detected in the scene of the vehicle-mounted equipment, the direction control is finished; in other scenarios, whether this time direction control is ended is determined by other means.

206, controlling the first direction control application to process the video data to obtain the video image.

Since the first direction control is applied to an independent CPU core, the processing capability of the independent CPU core is much stronger than that of a microprocessor, so that the independent CPU core can be fully utilized to process video data to obtain a processed video image.

Specifically, as shown in fig. 3, the step of controlling the first direction control application to process the video data to obtain the video image includes the following steps 301 to 305.

301, controlling the first direction control application to acquire each frame of initial direction control image data in the video data according to the status bit of the camera.

The acquired video data from the camera is initial direction control image data of one frame by one frame, and as in the scene of the in-vehicle apparatus, the initial direction control image data is also understood as initial reverse image data. The camera is provided with a corresponding state bit to represent the state of the camera, when the camera shoots a frame of initial direction control image data, the state bit of the camera is modified to represent that the initial direction control image data exists in the camera, and other associated hardware can acquire the initial direction control image data to process the initial direction control image data. If the status bits corresponding to the camera are represented by 0 and 1, 0 indicates that there is no initial direction control image data in the camera, and 1 indicates that there is initial direction control image data in the camera. And after the camera shoots a frame of initial direction control image data, the state bit of the camera is modified from 0 to 1. And the first direction control application inquires the state bit of the camera, acquires the frame initial direction control image data if the state bit of the camera is 1, and sends the frame initial direction control image data to the next processing unit for processing. In this way, the control first direction control application acquires each frame of initial direction control image data from the camera shooting through the camera interface.

It can be understood that the first CPU core is a bare core, and is not currently interrupted by resources, and therefore, the corresponding software program needs to acquire the status bit of the associated hardware of the first direction control application in a query manner.

And 302, sending each frame of initial direction control image data to an image processing unit for image processing to obtain image processed intermediate direction control image data, and modifying the state bit of the image processing unit.

The image processing unit may be configured to perform various processing on the image, such as filter processing, blur removal processing, and the like, to obtain image data for controlling the middle direction after the image processing. The image processing unit is provided with a corresponding state bit, and after the image processing unit completes the processing of the image data of the initial direction of one frame, the state bit of the image processing unit is modified to indicate that the image processing unit has the image data of the middle direction after the image processing. For example, the status bits corresponding to the image processing units are represented by 0 and 1, so that after the image processing unit completes processing, the status bit of the image processing unit is modified from 0 to 1, the first direction control application queries the status bit of the image processing unit (for example, the status bit is 1), and sends the frame middle direction control image data to the next processing unit for processing according to the value of the status bit. After the frame of intermediate direction control image data is sent to the next processing unit, if the intermediate direction control image data which is not processed by the image processing unit is currently finished, the state bit is modified, and the state bit is modified from 1 to 0.

It should be noted that, in the embodiment of the present application, the status bits are represented by 0 and 1 as an example, in other embodiments, the status bits may be represented by any value, such as yes and no, 1 and-1, and so on.

In one case, after the image-processed intermediate direction control image data is obtained, the image-processed intermediate direction control image data may be directly transmitted to the display unit for display processing.

303, according to the status bit of the image processing unit, sending the image processed intermediate direction control image data to the distortion correction unit for distortion correction processing to obtain the distortion corrected intermediate direction control image data, and modifying the status bit of the distortion correction unit.

Wherein the distortion correction processing unit is operable to de-distort the image. The image data obtained by shooting through the camera often has certain distortion, and after distortion correction processing is carried out, the image data is controlled in the middle direction after the distortion correction processing is carried out, so that the finally obtained video image looks easier to understand, and the user experience is improved. In particular, when the camera is a fisheye camera, distortion of image data captured by the fisheye camera is large, and it is necessary to perform distortion correction processing on the image data captured by the fisheye camera.

Wherein, the distortion correction processing unit is consistent with the image processing unit and is also correspondingly provided with a state bit. Assuming that the status bits are represented by 0 and 1, when the distortion correction unit completes the distortion processing of the received one-frame image processed intermediate direction control image data, the status bits of the distortion correction unit are modified to represent that the distortion corrected intermediate direction control image data exists in the current distortion correction unit. The first direction control application queries the status bit (e.g., status bit is 1) of the distortion correction processing unit and sends the frame middle direction control image data to the next processing unit for processing according to the value of the status bit. After the frame of intermediate direction control image data is sent to the next processing unit, if the intermediate direction control image data which is not processed by the distortion correction processing unit is not processed, the state bit of the distortion correction processing unit is modified, and the state bit is modified from 1 to 0. Please refer to the description of the image processing unit above, which is not described herein again.

And 304, according to the status bit of the distortion correction unit, sending the intermediate direction control image data to the display unit for display processing to obtain target direction control image data, and modifying the status bit of the display unit.

Wherein the processing of the display unit comprises rotation, color transformation, etc. The display unit obtains the target direction control image data after performing display processing, and the processing of the display unit is mainly to enable the corresponding image data to be displayed on a display screen.

Similarly, the display unit is consistent with the image processing unit, and is also correspondingly provided with a status bit. And setting the status bits to be 0 and 1, and modifying the status bits of the display unit to indicate that the target direction control image data after display processing exists in the current display unit when the display unit finishes the display processing of the received frame of middle direction control image data. The first direction control application sends the frame target direction control image data to the display screen for display by inquiring the status bit (for example, the status bit is 1) of the display unit and according to the value of the status bit. After the frame of target direction control image data is sent to the display screen, if the target direction control image data which is processed by the display unit is not processed currently, the state bit of the display unit is modified, and the state bit is modified from 1 to 0. Specifically, please refer to the description of the image processing unit above, which is not repeated herein.

The image data is controlled in accordance with a plurality of target directions after the display processing by the display unit 305, and a video image is formed.

And combining the plurality of target direction control image data after the display processing of the display unit according to a time sequence to form a video image.

The steps are used for processing the video data from the camera to obtain the video image. It should be noted that, in this embodiment of the application, the first CPU core and the second CPU core have one interrupt resource, and since the second CPU core is used to start an operating system of the electronic device, during the starting process of the operating system, the use of the interrupt resource (the interrupt resource is not used to detect the direction control signal) is necessarily involved, in order not to affect the starting process of the operating system in the second CPU core, the interrupt resource needs to be given to the second CPU core, and the first CPU core does not have a corresponding interrupt resource (interrupt hardware resource). Since there is no corresponding interrupt resource in the first CPU core, the first CPU core cannot acquire the corresponding event in an interrupt manner, and instead polls the state (status bit) of the relevant hardware unit through a software program in the first CPU core, and controls the data flow from one hardware unit to the next hardware unit.

It is understood that the system architecture on the electronic device chip is not an SMP architecture (Symmetric Multi-Processor) or an AMP architecture (Symmetric Multi-Processor), but an architecture between the SMP architecture and the AMP architecture. The advantage of this architecture is that, compared to AMP systems, there is no need to design a separate set of interrupt hardware resources for bare-metal deployment programming; compared with an SMP system, in a scene without using virtualization, a separate application (such as a bare metal deployment program) can be run outside a main operating system (such as an Android system).

And 207, controlling the first direction control application to display the video image on the display screen of the electronic equipment.

And displaying the video image on a display screen through a display interface so as to display the video image in real time. Specifically, after the status bit of the display unit indicates that the target direction control image data exists in the display unit, the target direction control image data is sent to the display screen through the display interface to be displayed.

The embodiment describes that after the first direction control application is started, when the first CPU core detects a direction control signal and does not receive a start notification sent by the second CPU core that the operating system has been started, the first direction control application is controlled to perform corresponding processing, so as to quickly realize display of a video image.

In some cases, as shown in fig. 2, the direction control application launching method further includes steps 208 to 209. The details may be further understood in conjunction with fig. 5.

And 208, when the first CPU core does not detect the direction control signal and receives a starting notice that the operating system is started and sent by the second CPU core, controlling the first CPU core to close the bare metal deployment program.

And detecting whether a direction control signal exists or not, if the direction control signal is not detected, and receiving a starting notice that the operating system is started and sent by the second CPU core, the fact that the direction control is not needed currently, the video image is not needed to be displayed, and the operating system is started means that the first CPU core is controlled to close the bare metal deployment program, and the first direction control application is ended. And closing the bare metal deployment program, namely, relating the first direction control application.

In some cases, when a start notification that the operating system is started is received and the direction control signal is not detected, the first CPU core is controlled to modify a state flag bit corresponding to the first CPU core in the memory, and the use state of the first CPU core is represented by the state flag bit. The value of the status flag bit includes a first flag value and a second flag value, the first flag value indicates that the direction control is not completed and the corresponding first CPU core is in use, the second flag value indicates that the direction control is completed and the corresponding first CPU core is not in use. And when a starting notice that the operating system is started and the direction control signal is not detected, which is sent by the second CPU core, controlling the first CPU core to modify the corresponding state zone bit in the memory, and modifying the value of the state zone bit from the first zone bit value to the second zone bit value. Before releasing the first CPU core, controlling the first CPU core to modify the corresponding status flag bit in the memory. Modifying the corresponding status flag bit in the memory means that the associated hardware and the first CPU core can be released.

And 209, controlling the first CPU core to release the associated hardware and release the first CPU core.

And after the first direction control application is finished, controlling the first CPU core to release the associated hardware so that a subsequent operating system can acquire the use right of the associated hardware. The first CPU core is released because the current operating system is up and there is no need to deploy the program using the bare metal.

And after the first CPU core is released, controlling the first CPU core to be powered off through the operating system of the second CPU core.

In some cases, during a cold start of the electronic device, the direction control signal is not detected, and thus after the first CPU core is controlled to start the first direction control application, when the first CPU core receives a start notification sent by the second CPU core that the operating system is started, the first CPU core is controlled to close the bare metal deployment program, and to release the associated hardware, and release the first CPU core.

On the basis of the above-described embodiment, after releasing the first CPU core, as shown in fig. 4, the direction control application starting method further includes the following steps 401 to 404. The details can be further understood in conjunction with fig. 5.

401, the second CPU core is controlled to detect whether the first CPU core has been released.
