Technical field

Background technique

Therefore, the startup speed of the display device is a key parameter that characterizes the performance of the device, which directly affects the user experience. Generally, the display device needs to light up the display and start the operating system during the startup process.

Among them, the serial dot screen mode, that is, the processor in the display device (such as the Central Processing Unit, CPU) sequentially executes the process of lighting the display and starting the operating system kernel, and then enters the operating system kernel to start the display device . Timer screen mode, that is, the processor needs to set interrupts and timers during each startup process, and take an operation in the light-up display as a timer event, and then, the processor first executes the light-up display For the remaining operations other than this operation, configure the timer event, load the operating system kernel after the configuration is completed, then execute the timer event, and start and enter the operating system kernel after the timer event execution ends to start the display device.

detailed description

Fig. 1 is an exploded view of an exemplary display device provided by an embodiment of the application. As shown in Fig. 1, the display device is illustrated by taking a TV as an example. The display device may include: a housing 1, a display screen 2, a power board 3 and motherboard 4. In addition, the TV in Figure 1 may also include brackets, connectors and other components.

The housing 1 is provided with a power supply board 3 and a main board 4, the display screen 2 can be embedded on the inner surface of the housing 1, the housing 1 plays a role of connection, protection and beauty, and the display screen 2 can provide a display screen. Wherein, the housing 1 can be the housing of an existing TV, or other forms of housing. This application does not limit the specific material, shape, size, and specific structure of the housing 1.

The power board 3 is respectively connected to the display screen 2 and the main board 4 (not shown in FIG. 1), so that the power board 3 can supply power to the display screen 2 and the main board 4 respectively to provide different levels of power. Among them, the power board 3 may adopt one or more circuit boards. The power board 3 specifically includes but is not limited to hardware components such as a voltage converter, an AC-DC converter, a DC-DC converter, and a filter.

The display screen 2 is connected to the main board 4 (not shown in FIG. 1), so that the display screen 2 can receive the display data sent by the main board 4 for normal display. This application does not limit the specific shape, size and type of the display screen 2. For example, the display 2 is a liquid crystal display.

In the prior art, multiple central processing units (CPUs) are provided on the motherboard 4, and each CPU may generally include arithmetic logic components, register components, and control components. Among them, the register component is a small area of multiple CPUs that can be used for configuration and storage of parameters, and is usually used as a common storage area of multiple CPUs (this common storage area can be used as a feasible area of the reserved area mentioned in this application). Method to realize).

On the one hand, certain identification bits can be stored in the register component, so that multiple CPUs can identify the identification bits to determine the corresponding function.

On the other hand, the register component can also store a boot program (Bootrom) solidified in multiple CPUs, where the Bootrom is used to guide the CPU to execute the Boot program, and the Boot program is used to boot the display device to start, that is, the display device is on the After powering on, the CPU can start from the Bootrom and enter the boot program to realize the startup of the display device.

Among them, the boot program includes all the programs involved in the two processes of illuminating the display screen 2 and starting the operating system kernel 13 of the display device and the parameters required for the program to run. The operating system kernel 13 is the core part of the operating system, which is mainly used to manage the processes, memory, device drivers, files, and network systems of the operating system, and determines the performance and stability of the operating system. The operating system may include, but is not limited to, Linux, Android and other operating systems.

In addition, the main board 4 is also provided with a flash memory 51 (Flash Storage), a memory 52 and a memory controller 53.

The flash memory 51 is a non-volatile memory, which has the characteristic that data will not be lost after power failure, and is specifically used to store data required when the display device is started, such as a program and parameters required when the program is running. For example, the boot program, the operating system kernel 13 for normal operation, and the operating system kernel for resetting. The flash memory 51 may include multiple types, such as embedded multimedia card (eMMC), universal flash storage (UFS) memory, or read-only memory (ROM), or Other types of static storage devices that can store static information and instructions.

The memory 52 is a volatile memory, which has the characteristics of fast data read and write speed, and is specifically used to provide a cache area for data that needs to be used when multiple CPUs are running. The memory 52 may specifically include various types of random-access memory (RAM) or other types of dynamic storage devices that can store information and instructions, for example, double data rate synchronous dynamic RAM (double data rate synchronous dynamic RAM). , DDR SDRAM).

The memory controller 53 is used to decode various read and write requests of the memory (that is, the flash memory 51 or the memory 52) issued by the main CPU. It can be an independent device separated from the flash memory 51 and the memory 52 as shown in FIG. 2, It can also be integrated in the flash memory 51 or the memory 52 to specifically manage the access request of the corresponding memory.

In addition, the memory may also include Electrically Erasable Programmable Read-Only Memory (EEPROM), CD-ROM (Compact Disc Read-Only Memory, CD-ROM) or other optical disk storage, optical disk storage (including Compact discs, laser discs, optical discs, digital universal discs, Blu-ray discs, etc.), magnetic disk storage media or other magnetic storage devices, or any program code that can be used to carry or store program codes in the form of instructions or data structures and that can be accessed by a computer Other computer-readable storage media, but not limited to this.

In addition, multiple CPUs are generally considered to be a master CPU and at least one slave CPU. The master CPU executes the startup process of the display device, while other slave CPUs do not perform any operations during the startup process of the display device. Those skilled in the art can understand that the startup process of the display device not only needs to light up the display screen 2 of the display device, but also needs to start the operating system. Therefore, after the display device is powered on, the main CPU reads the boot program in the flash memory 51 into the memory 52 under the guidance of the Bootrom in the register component, and executes the boot program in the memory 52 to start the display device.

In the following, the specific implementation process of the main CPU starting the display device will be described in detail using the serial dot screen mode and the timer dot screen mode.

In a possible implementation manner, the main CPU can adopt a serial dot screen mode to implement the startup process of the display device. The specific process is: the main CPU can first power on the timing controller (TCON), then turn on the interface (Interface, Intf) between the motherboard 4 and the display 2, and then wait for a period of time (such as 1500ms) before the display Backlight in 2 is turned on. After the Backlight lights up, the main CPU starts to load the operating system kernel 13, which reads from the flash memory 51 the reference implementation software (ARM (Advanced RISC Machines) Trusted Firmware, atf) provided by the ARM processor in turn, and the kernel (kernel) , Such as Linux Kernel, an open source Unix-like operating system macro kernel) and for kernel analysis (Device-Tree blob, dtb). Finally, the main CPU runs the operating system kernel 13 in the memory 52 to guide the operating system kernel 13 to start.

It should be noted that the TCON is usually set on the TCON board, and the TCON board can be set on the main board 4 or separately from the main board 4, which is not limited in this application. Generally, during the process of lighting the display screen 2, when the TCON board is set on the main board 4, the main CPU can first power on the TCON. When the TCON board is set separately from the main board 4, the main CPU does not need to power on the TCON, and the TCON can be powered on actively.

In another possible implementation, the main CPU can use the timer point screen mode to realize the startup process of the display device. The specific process is: the main CPU can initialize the interrupt and the timer, and then execute the TCON power on, open the Intf interface, Configure the timer event and enable the timer event. The specific content of the timer event is a period of time (for example, 1500ms) and then the Backlight is turned on. Then, after the configuration is completed, the main CPU starts to load the operating system kernel 13, that is, read atf, kernel, and dtb from the flash in sequence. Then, after the timer event is completed, the main CPU runs the operating system kernel 13 in the memory 52 to guide the operating system kernel 13 to start.

In the serial dot screen mode, the main CPU needs to sequentially complete the two processes of lighting the display screen 2 and starting the operating system kernel 13 of the display device, which consumes a lot of startup time. In the timer screen mode, the main CPU needs to initialize the interrupt and timer each time, and after the process of starting the operating system kernel 13 is completed, it needs to wait for the timer event to end before entering the operating system kernel 13, which consumes a lot of startup time. Therefore, in the actual application process, no matter whether the main CPU adopts the serial dot screen mode or the timer dot screen mode, it will take a lot of time, which limits the startup speed of the display device.

In order to solve the above-mentioned problems, the present application provides a processing method, device, equipment and storage medium for starting the device, which can save the starting time of the display device and improve the starting speed of the display device. In the following, in combination with specific embodiments, the specific implementation process of the processing method of the activation device of the present application will be described in detail.

Further, on the basis of the embodiments in FIG. 1 to FIG. 3, FIG. 4 is a signaling flowchart of an exemplary processing method for starting the device provided in an embodiment of the application. As shown in FIG. 4, the processing method of the activation device 10 of the present application may include:

S101. The first processor starts the second processor.

In this application, the boot program in the prior art can be divided into the first part of the program and the second part of the program.

The execution subject of the first part of the program is the first processor 11, which is used to start the second processor 12 and the operating system kernel 13 of the display device. The first part of the program may include, but is not limited to: a boot program and an operating system kernel 13, where the boot program may include an operating program for starting the second processor 12, an initialization program for the first processor 11, and the like.

The execution body of the second part of the program is the second processor 12, which is used to light up the display screen. The display screens may be one or more, which may specifically be a display screen in a display device or a separately set display screen. This application does not limit this. For ease of description, the display screen is illustrated with the display screen 2 in the display device shown in FIG. 1. Among them, the second part of the program may include, but is not limited to: an initialization program of the second processor 12, a screen point program, and screen parameter information.

Those skilled in the art can understand that after the display device is powered on, only one of the multiple CPUs can be started, and the remaining CPUs are in an unstarted state. Therefore, in this application, the first processor 11 is set as the CPU that is started after the display device is powered on, and the second processor 12 is set as one of the CPUs that are not started after the display device is powered on. Furthermore, after the display device is powered on, the first processor 11 can enter the boot program through Bootrom in the register component, and in order to realize the lighting of the display screen 2, the first processor 11 needs to start the second processor 12.

Based on the respective characteristics of the flash memory 51 and the memory 52, usually the boot program is stored in the flash memory 51, and the boot program runs in the memory 52. Therefore, in order to start the second processor 12, the first processor 11 may write the boot program in the flash memory 51 into the memory 52, where the boot program includes an operating program for starting the second processor 12, the first The processor 11 executes an operation program for starting the second processor 12 in the memory 52. Specifically, the first processor 11 may power on the second processor 12 according to the instruction of the boot program, so as to implement the process of starting the second processor 12 by the first processor 11.

In addition, the boot program may also include a first initialization program, and the first initialization program is used to initialize the processor 11. Before or after starting the second processor 12, the first processor 11 may execute the first initialization program in the memory 52. Specifically, the first processor 11 may initialize and configure various parameters of the first processor 11 according to the first initialization program, so as to realize the initialization of the first processor 11.

S102. The second processor lights up the display screen.

Those skilled in the art can understand that one of the multiple CPUs can write the boot program from the flash memory 51 to the memory 52, so that multiple CPUs can execute the boot program in the memory 52.

After S101, the second processor 12 has been started. Therefore, in order to enable the second processor 12 to work normally, the first processor 11 may write the second initialization program in the flash memory 51 into the memory 52 before the second processor 12 lights up the display screen 2. The second initialization program is used to initialize the second processor 12 and execute the second initialization program in the memory 52. Specifically, the second processor 12 may initialize and configure various parameters of the second processor 12 according to the second initialization program, thereby realizing the initialization of the second processor 12.

Moreover, in order to enable the second processor 12 to smoothly light up the display screen 2, the first processor 11 may write the screen point program and screen parameter information in the flash memory 51 to the display screen 2 before the second processor 12 lights up the display screen 2. 52 in the memory. Generally, for different types of display screens 2, the point screen procedure and screen parameter information will be different, and in order to adapt to different display requirements, the point screen procedure and screen parameter information will also be different.

Among them, the screen point program is used to control the lighting of the display screen 2. The specific control process may include but is not limited to: powering on the display screen 2, preparing for the second processor 12 to perform lighting of the display screen 2, and turning on the display Backlight in screen 2, etc.

The screen parameter information is the information required for display on the screen 2. This application does not limit the implementation of screen parameter information. Optionally, the screen parameter information includes at least one of the following information: the resolution of the display screen 2, the type of the interface (Interface, Intf) between the activation device 10 and the display screen 2, and the backlight ( Backlight) delay and various timing information. The timing information includes, but is not limited to, the power-on timing of Intf, the data transmission timing of Intf, and the power-on timing of TCON.

It should be noted that since the first processor 11 and the second processor 12 can be used as independent arithmetic units, the first processor 11 and the second processor 12 can work at the same time. Since the second processor 12 needs to use the screen program and screen parameter information to light up the display screen, it takes time for the processor 11 to write the screen program and screen parameter information from the flash memory 51 into the memory 52, in order to further save startup time After the processor 11 writes the second initialization program into the memory 52, the second processor 12 can perform initialization without waiting for the processor 11 to write all the information used by the second processor to light the display screen 2 into the memory 52 After the initialization is performed, the first processor 11 can write the screen program and screen parameter information in the flash memory 51 into the memory 52 during the initialization of the second processor 12, so that the second processor 12 executes There is a time overlap between the initialization process and the read program executed by the first processor 11 and the parameter process during program execution, which further reduces the startup time of the display device.

Wherein, since the initialization process performed by the second processor 12 lasts for a relatively short time, the first processor 11 and the second processor 12 can execute their respective operation processes at the same time, or the first processor 11 can also first communicate with the first processor 11 The second processor 12 executes the corresponding operation process and ends the respective operation process at the same time, so that the time overlap of the two processes is the duration of the initialization process performed by the second processor 12, that is, the time overlap is the largest. In this way, the display device The effect of saving startup time is the best.

In addition, the first processor 11 and the second processor 12 both need to execute their respective operation processes in the memory 52, and it is inevitable that the same program and/or program execution parameters will be called during the respective execution processes. If any one of the first processor 11 and the second processor 12 needs to modify the program and/or the parameters during program execution, the other processor will use the modified program and/or the parameters during program execution. Causes an error or failure in the operation of the processor. Therefore, the first processor 11 writes the screen program and screen parameter information into the reserved area of the memory 52, so that the second processor 12 is configured in the reserved area according to the point The screen program and screen parameter information light up the display screen 2. The reserved area is used to store the program and information used by the second processor to light up the display screen 2.

Wherein, the reserved area is different from the area where the first processor 11 performs the corresponding operation. In this application, the size of the reserved area can be set according to the screen point program and the size of the screen parameter information. Generally, the size of the reserved area is larger than the size of the screen program and screen parameter information. In general, the size of the reserved area can be represented by the start address and the length of the reserved area. For example, the initial address of the reserved area may be the address 0xYYYYYYYY in the memory. The area length of the reserved area is XX bytes.

Optionally, in order for the second processor 12 to quickly learn that the first processor 11 has written the screen program and screen parameter information into the memory 52, the present application may use various methods to inform the second processor 12 to start execution. Operation of bright display 2. The following two methods are used for illustration.

In a possible implementation manner, after the first processor 11 writes the screen point program and screen parameter information into the memory 52, it may send the first message to the second processor 12, so that the second processor 12 is receiving When the first message is reached, the display 2 is turned on.

The first message is used to indicate that the screen program and screen parameter information have been written in the reserved area, and the first message may adopt a number, a code, or an identification. For example, when the first message includes the mark "A", it means that the screen program and screen parameter information have been written in the reserved area. When the label "A" is not included in the first message, it means that the screen program and screen parameter information have not been written in the reserved area.

In another possible implementation manner, the present application may set a first identification bit, and the first identification bit may be located in the memory 52 or in the register components of the first processor 11 and the second processor 12. Furthermore, after the first processor 11 writes the screen program and screen parameter information into the memory 52, the value of the first identification bit is changed to the first preset value, so that the second processor 12 is determining the first identification When the digit is the first preset value, the display 2 is lit.

The first preset value is used to indicate that the screen program and screen parameter information have been written in the reserved area. For example, when the first identification bit is the first preset value "1", it means that the screen program and screen parameter information have been written in the reserved area. The value of the first identification bit is "0", and when it is not the first preset value "1", it means that the screen program and screen parameter information has not been written in the reserved area.

Further, the second processor 12 may execute a screen tap program based on the screen parameter information in the memory 52. Specifically, the second processor 12 may perform a corresponding touch operation on the display screen 2 according to the touch screen program and screen parameter information. For example, the second processor 12 may first power on a timing controller (TCON). Prepare for the normal display of the display 2, and then turn on the interface (Intf) between the main board 4 and the display 2 to correct the clock of the display 2 to parse the data and transmit the screen parameter information to the display 2, and then wait for a period of time (Such as 1500 ms), the backlight in the display screen 2 is turned on, so that the second processor 12 lights up the display screen 2.

S103. The first processor starts the operating system kernel when the second processor lights up the display screen.

In order to enable the first processor 11 to smoothly start the operating system kernel 13, the first processor 11 may write the operating system kernel 13 in the memory 52 into the memory 52 before starting the operating system kernel 13. In general, the operating system kernel 13 will be different if the operating system of the display device is different.

The operating system kernel 13 may include, but is not limited to: atf, kernel, such as Linux Kernel and dtb.

Since the first processor 11 and the second processor 12 can work at the same time and can be used as independent arithmetic units, therefore, the first processor 11 may be able to turn on the display screen 2 in the process of the second processor 12 in S102. The operating system kernel 13 is started, so that the process of starting the operating system kernel 13 executed by the first processor 11 and the process of lighting the display screen 2 executed by the second processor 12 overlap in time, which reduces the startup time of the display device.

It should be noted that there is no time sequence between S102 and S103, and S102 and S103 can be executed simultaneously or sequentially. In order to achieve the best effect of saving startup time for the startup device, the first processor 11 and the second processor 12 can execute their respective operation processes at the same time, or the first processor 11 can also execute corresponding operations with the second processor 12 first. The operation process, and the respective operation processes are ended at the same time, so that the time overlap of the two processes is maximized, so that the startup time of the display device is greatly saved.

S104. After the operating system kernel is started, the first processor runs under the instruction of the operating system kernel.

Since the operating system kernel 13 is started by the first processor 11, after the operating system kernel 13 is started, the first processor 11 can be directly controlled by the operating system kernel 13, so that the first processor 11 can be in the operating system It runs under the instructions of the kernel 13, that is, the first processor 11 can perform corresponding operations according to the instructions of the operating system kernel 13.

S105. After the second processor finishes lighting the display screen, the second processor runs under the instruction of the operating system kernel.

After the second processor 12 finishes lighting the display screen 2, it is convenient to be in the idle state, that is, the WFI (Wait for interrupt) state. At this time, the second processor 12 is not under the control of the operating system kernel 13 (this The control means that the operating system kernel 13 cannot call the second processor 12 to perform any operation, nor can it supervise the interface of the second processor 12 to obtain the required data), therefore, in order to improve the processing capacity of the display device After the second processor 12 finishes lighting the display screen 2 and the operating system kernel 13 starts, the second processor 12 can be controlled by the operating system kernel 13, so that the second processor 11 can be instructed by the operating system kernel 13 Down-run, that is, the second processor 12 performs a corresponding operation process according to the instructions of the operating system kernel 13, so as to avoid the waste of the second processor 12 which may affect the performance of the display device.

Optionally, after the first processor 11 starts the operating system kernel 13, since the first processor 11 can run under the instruction of the operating system kernel 13, the operating system kernel 13 can instruct the first processor 11 to determine Whether the second processor 12 finishes lighting the display screen 2 so that the first processor 11 can notify the second processor 12 that it can run under the instruction of the operating system kernel 13 in various ways. The following two methods are used for detailed description.

In a possible implementation manner, the second processor 12 may send the second information to the first processor 11, so that when the first processor 11 receives the second message, the second processor 12 is notified that the operating system kernel Run under 13 instructions.

The second message is used to indicate that the second processor 12 has turned on the display screen 2, and the second message may adopt a number, a code, or an identification. For example, when the second message includes the identifier “A”, it means that the second processor 12 has turned on the display screen 2. When the identifier “A” is not included in the second message, it means that the second processor 12 has not finished lighting the display screen 2.

In another possible implementation manner, a second identification bit may be set in the present application, and the second identification bit may be located in the memory 52 or in the memory components of the first processor 11 and the second processor 12. Furthermore, the second processor 12 changes the value of the second identification position to the second preset value after the display screen 2 is turned on, so that when the first processor 11 determines that the second identification position is the second preset value, The second processor 12 is notified to run under the instruction of the operating system kernel 13.

The second preset value is used to indicate that the second processor 12 has turned on the display screen 2. For example, when the second identification bit is the second preset value “1”, it means that the second processor 12 has turned on the display screen 2. The value of the second identification bit is “0”, and when it is not the second preset value “1”, it means that the second processor 12 has not finished lighting the display screen 2.

Based on the contents of S104 and S105, both the first processor 11 and the second processor 12 are controlled by the operating system kernel 13. Specifically, the operating system kernel 13 can distribute tasks to the first processor 11 and the second processor 12 according to the respective utilization, frequency and power consumption of the first processor 11 and the second processor 12, and instruct the first The processor 11 and the second processor 12 perform corresponding operations. In addition, the operating system kernel 13 can also implement processes such as network connection, U disk identification, and read and write operations.

Optionally, after the second processor 12 finishes lighting up the display screen 2, the reserved space may be released. Therefore, after S104 is completed, the booted operating system kernel 13 may instruct the first processor 11 to release the reserved area after the second processor 12 lights up the display screen 2, so as to save the available area of the memory 52. Since the first processor 11 knows the specific location of the reserved area, after the second processor 12 finishes lighting the display screen 2, it can notify the first processor 11 of the second message or the second preset value. The second processor 12 has turned on the display screen 2, so that the first processor 11 can release the reserved area. In addition, after S105 is completed, the booted operating system kernel 13 may instruct the second processor 12 to release the reserved area, so as to save the available area of the memory 52. Specifically, since the second processor 12 knows the specific location of the reserved area, the second processor 12 can directly release the reserved area.

In a specific embodiment, in the prior art, it takes 3 s (seconds) to start the display device in the serial dot screen mode, and 2146 ms (milliseconds) in the timer dot screen mode. However, it takes 794 ms for the activation device 10 to use the processing method of the activation device 10 of the present application to activate the display device, which greatly reduces the activation time.

The processing method of the activation device provided in this application uses the first processor and the second processing in the activation device as independent arithmetic units. After the display device including the startup device and the display screen is powered on, the first processor automatically starts, and the first processor starts the second processor. Furthermore, the second processor lights up the display screen, and while the second processor lights up the display screen, the first processor starts the operating system kernel, so that the first processor and the second processor perform their operations in parallel The process makes the two operation processes overlap in time, thereby reducing the startup time of the display device and improving the startup speed of the display device.

On the basis of the embodiments in FIGS. 1 to 4, the activation device 10 in this application can be compatible with the reset function of the display device. Hereinafter, in conjunction with FIG. 5, the specific implementation process of the activation device 10 to reset the display device will be described in detail.

S201. The first processor receives a reset signal.

In this application, the first processor 11 in the activation device 10 may receive a reset signal used to indicate that the display device is reset. Wherein, the reset signal may be generated when the reset button set on the starting device 10 is pressed, or may be sent to the first processor 11 through software and/or hardware when the reset button on the display device is pressed. of. In addition, the first processor 11 may receive the reset signal at any time during the startup process of the display device and the working process after startup. The reset button can be arranged on the starting device 10 and connected to the casing 1. The reset button can extend out of the casing of the casing 1, or the edges of the casing 1 can be flush, which is not limited in this application. The reset button can also be arranged on the button board of the casing 1 of the display device for convenient operation. And this application does not limit the specific number and specific types of reset buttons.

S202: The first processor starts the second processor.

S203. The second processor lights up the display screen.

S2041. The first processor writes the operating system kernel corresponding to the reset signal in the non-volatile memory into the volatile memory.

S2042. The first processor starts the operating system kernel corresponding to the reset signal.

Specifically, when the operator needs to reset the display device, the operator can press the reset button, so that the first processor 11 can receive the reset signal. The first processor 11 can start the display device when receiving the reset signal (starting here means that if the display device is not started, the display device will start to start, and if the display device is already started, the display device will restart) . During the startup process of the display device, the first processor 11 may start the second processor 12.

At this time, both the first processor 11 and the second processor 12 have been started. The second processor 12 can light up the display screen 2 of the display device. The first processor 11 can write the operating system kernel corresponding to the reset signal in the flash memory 51 into the memory 52, and then start the operating system kernel corresponding to the reset signal to restore the display device to a normal working state to meet actual requirements.

The operating system kernel corresponding to the reset signal and the operating system kernel 13 in the flash memory 51 may be of the same version or different versions, which is not limited in this application. Specifically, the operating system kernel corresponding to the reset signal is usually used to perform the reset operation. The specific operations involved in the reset operation may include, but are not limited to, clearing the cache and restoring each parameter of the boot device 10 to preset values, such as factory settings or values from the last software update. The cache may include, but is not limited to, junk files, system cache, and application cache. Each parameter includes but is not limited to the size of the cache space, the type of interface, and so on.

It should be noted that S2041 is executed with S2042 first, and S203 and S2041 can be executed simultaneously or sequentially, which is not limited in this application.

S205. After the operating system kernel corresponding to the reset signal is started, the first processor runs under the instruction of the operating system kernel corresponding to the reset signal.

Specifically, after the operating system kernel corresponding to the reset signal is started, the first processor 11 runs under the instruction of the operating system kernel corresponding to the reset signal. For the specific process, refer to S104 shown in FIG. 4, which will not be repeated here.

S206. After the second processor finishes lighting the display screen, the second processor runs under the instruction of the operating system kernel corresponding to the reset signal.

S207: The first processor and/or the second processor perform a reset operation under the instruction of the operating system kernel corresponding to the reset signal.

Specifically, the operating system kernel corresponding to the reset signal can instruct the first processor 11, or the second processor 12, and can also instruct the first processor 11 and the second processor 12 to perform reset operations, such as clearing cache and /Or restore each parameter of the starting device 10 to a preset value, such as a factory-set value or a value from the last software update. Thus, the reset function of the boot device 10 compatible with the display device is realized, so that the processing process of the display device is smoother, and the operation performance of the display device is improved.

Furthermore, after the display device is reset, the starting device 10 will not continue to stay in the current state, and usually restart the display device, so that the display device enters a normal working state. Specifically, after the first processor 11 and/or the second processor 12 perform the reset operation, the operating system kernel corresponding to the reset signal may instruct the first processor 11, the second processor 12, or the second processor 12 A processor 11 and a second processor 12 perform the operation of restarting the display device. Furthermore, the activation device 10 then executes the specific process of the embodiment in FIG. 4, which will not be repeated here. It should be noted that during the restarting process of the display device, the first processor 11 starts the operating system kernel 13, not the operating system kernel corresponding to the reset signal.

In this application, on the basis of saving the startup time of the display device, the reset function of the display device can also be taken into consideration. Specifically, when the first processor receives the reset signal, it can write the operating system kernel corresponding to the reset signal in the flash memory into the memory, so that the first processor can start the operating system kernel corresponding to the reset signal. The first processor and/or the second processor may perform a reset operation under the instruction of the operating system kernel corresponding to the reset signal to restore the display device to a normal working state, so as to meet actual requirements such as clearing the cache of the display device.

On the basis of the embodiments in FIGS. 1 to 4, the activation device 10 in this application can be compatible with the reset function of the display device. Next, in conjunction with FIG. 6, the specific implementation process of the empty disk upgrade of the display device by the activation device 10 will be described in detail.

S301. The first processor receives an empty disk upgrade signal.

In this application, the first processor 11 in the boot device 10 may receive an empty disk upgrade signal, which is used to indicate that the display device cannot be booted or displayed normally due to a software failure of the operating system kernel 13 .

Wherein, the empty disk upgrade signal may be generated when the power button provided on the starting device 10 is pressed, or may be sent to the first processor through software and/or hardware when the power button on the display device is pressed. 11's. In addition, the first processor 11 may receive the empty disk upgrade signal at any time during the startup process of the display device and the working process after startup. Wherein, the power button can be arranged on the starting device 10 and connected to the casing 1. The power button can extend out of the casing of the casing 1, or it can be flush with the edge of the casing 1, which is not limited in this application. The power button may also be arranged on the button panel of the housing 1 of the display device, and the specific number and specific type of the power button are not limited in this application.

The second processor reads the operating system kernel corresponding to the empty disk upgrade signal from another memory according to the empty disk upgrade signal, and replaces the operating system kernel corresponding to the empty disk upgrade signal with the operating system kernel in the non-volatile memory , The other memory is a memory other than the non-volatile memory and the volatile memory.

In this application, the operator can press the power button to restart the display device, and further, the first processor 11 can receive the empty disk upgrade signal, so that the first processor 11 can perform the empty disk upgrade operation. Specifically, in the process of restarting the display device, the first processor 11 can start the second processor 12, and then can send the empty disk upgrade signal to the second processor 12, and control the first processor 11 to be idle ( Idle) state, that is, WFI (Wait for interrupt) state, that is, the first processor 11 does not perform any operation.

Wherein, the first processor 11 may set an identifier in a fixed position in the register component, and the identifier is used to instruct the second processor 12 to perform an empty disk upgrade process for the display device. The first processor 11 may also send a message carrying an empty disk upgrade signal to the second processor 12 to inform the second processor 12 to perform the empty disk upgrade process on the display. This application processes the first processor 11 to the second processor. The specific implementation manner of sending the empty disk upgrade signal by the device 12 is not limited.

Furthermore, the second processor 12 can read the operating system kernel corresponding to the empty disk upgrade signal from another memory according to the empty disk upgrade signal, and replace the operating system kernel corresponding to the empty disk upgrade signal with the operating system kernel in the flash memory 51 13.
