FIG. 1 is a system boot process of the main CPU of the electronic device provided by the embodiment of the present invention, wherein the electronic device has a main CPU and a slave CPU, and the details are as follows:

In step S101, after the system is powered on, the main CPU guides the bootloader to initialize the peripherals and complete the configuration of the basic peripherals.

In step S102, the main CPU finishes booting the operating system platform, but does not initialize the audio and video hardware.

In this embodiment, the operating system is the LINUX operating system, and the main CPU completes the booting of the operating system platform and starts the LINUX operating system, but does not initialize the audio and video hardware during this process.

In step S103, the main CPU starts the main application program, and completes necessary initialization of the main application program.

In step S104, the main CPU waits for the completion of playing the startup screen.

In this embodiment, the master CPU polls the synchronization flag signal with the slave CPU, checks the working status of the slave CPU, and judges the playing status of the start-up screen according to the status.

In this embodiment, the slave CPU is a DSP.

In step S105, the main CPU judges whether the playing of the startup animation is completed.

If the master CPU finds that the slave CPU has finished playing the boot animation, it immediately executes step S106 , otherwise executes step S104 .

In step S106, the main CPU reads the parameters of the audio and video equipment, and takes over the audio and video equipment.

In step S107, the main CPU continues to run the main application program, outputs audio and video images such as the main menu through the audio and video equipment, and completes the booting process.

FIG. 2 is a method for playing a startup screen from a CPU of an electronic device provided in an embodiment of the present invention, wherein the electronic device has a master CPU and a slave CPU, and the details are as follows:

In step S201, after the system is powered on, the main CPU starts system booting, and reads startup parameters from the CPU to complete its own initialization and initialization of audio and video hardware.

In step S202, the start-up picture data stored in the specified address in the FLASH is read from the CPU, decompressed, decoded, and output to the audio and video hardware to play the start-up picture.

In this embodiment, the startup screen includes any one of audio, video, image, animation and the like.

Wherein, in this embodiment, after the master CPU completes the necessary initialization work for the master application program, it polls the synchronization flag signal with the slave CPU to check the working status of the slave CPU. Get the audio and video device parameters, and take over the audio and video device.

In step S203, after the start-up picture is played, the slave CPU saves the audio and video hardware initialization parameters, modifies the synchronization flag signal with the master CPU, and notifies the master CPU to continue running.

Among them, the communication data between the master CPU and the slave CPU must be stored in a memory area that can be accessed by both parties in the memory. In this embodiment, the master CPU and the slave CPU communication data, such as the synchronization flag of the master and slave CPUs, are stored in the 0x20008000 memory physical address.

In addition, the duration of the boot animation can be determined and produced according to the time required for the main CPU to complete the boot. Generally, the playback duration of the boot screen is selected to be less than or equal to the time required for the main CPU to complete the boot.

In addition, because the format of the boot screen can support formats such as RMVB and RM, wherein the file of the boot screen is stored in a section of storage space in the FLASH, in this embodiment, the file of the boot screen is stored at the offset address 0x100000 of the FLASH, The audio and video initialization parameters are stored at the offset address 0x200000 of the FLASH.
