Abstract

Booting display control method and associated apparatus are disclosed. The apparatus includes a processor chip, wherein the processor chip includes a processor and a display. After the processor chip is activated, the processor loads the leading program and displays control program; the processor detects whether a vehicle backing indicator indicates vehicle backing; when the vehicle backing indicator indicates vehicle backing, the processor controls the display controller to realize the vehicle backing video display function through the display control program; and when the vehicle backing indicator does not indicate vehicle backing, the processor loads the operating system program. Through the method, the present invention is capable of displaying vehicle backing video display when loading the operating system program.

Claims

1. A booting display control method, based on a processor chip which comprises a processor and a display controller, wherein the method comprises:

loading a leading program and a display control program by the processor after the processor chip is activated;

detecting whether a vehicle backing indicator indicates vehicle backing by the processor;

when the vehicle backing indicator indicates vehicle backing, executing the vehicle backing video display function through the display control program by the display controller; and

when the vehicle backing indicator does not indicate vehicle backing, loading an operating system program by the processor.

2. The booting display control method of claim 1, further comprising:

after the operating system program is completely loaded, controlling the display controller to execute the vehicle backing video display function by the processor through the display control program when the vehicle backing indicator indicates vehicle backing.

3. The booting display control method of claim 1, further comprising:

detecting vehicle backing status of vehicle backing control signal recursively by utilizing an external controller; and

passing the vehicle backing indicator corresponding to the vehicle backing status to the processor.

4. The booting display control method of claim 3, further comprising:

detecting a loading status of the operating system program recursively by utilizing the external controller; and

when the external controller detects that the vehicle backing status turns into vehicle backing from no vehicle backing and the operating system program is not completely loaded, reactivating the processor chip.

5. The booting display control method of claim 4, further comprising:

when the external controller detects that the vehicle backing status turns into no vehicle backing from vehicle backing and the operating system program is not completely loaded, reactivating the processor chip.

6. The booting display control method of claim 5, wherein the step of reactivating the processor chip further comprises:

controlling power or a reset pin of the processer chip via a General Purpose Input/Output (GPIO) interface to reactivate the processor chip.

7. The booting display control method of claim 4, wherein the step of reactivating the processor chip further comprises:

controlling power or a reset pin of the processer chip via a General Purpose Input/Output (GPIO) interface to reactivate the processor chip.

8. The booting display control method of claim 4, wherein the step of detecting the vehicle backing status of the vehicle backing control signal recursively by utilizing the external controller further comprises:

when the external controller is activated and the vehicle backing indicator indicates no vehicle backing, configuring a reactivation status indicator to a first status;

detecting whether the vehicle backing control signal indicates vehicle backing, and detecting whether the reactivation status indicator indicates the first status;

when the vehicle backing control signal indicates vehicle backing, and the reactivation status indicator indicates the first status, determining the vehicle backing status turns into vehicle backing from no vehicle backing, and configuring the reactivation status indicator to a second status; and

when the vehicle backing control signal indicates no vehicle backing, and the reactivation status indicator indicates the second status, determining the vehicle backing status turns into no vehicle backing from vehicle backing, and configuring the reactivation status indicator to the first status.

9. A booting display control apparatus, including a processor chip, wherein the processor chip comprises:

a processor; and

a display controller, coupled to the processor;

wherein after the processor chip is activated, the processor loads a leading program and a display control program;

the processor detects whether a vehicle backing indicator indicates vehicle backing;

when the vehicle backing indicator indicates vehicle backing, the processor controls the display controller to execute the vehicle backing video display function through the display control program; and

when the vehicle backing indicator does not indicate vehicle backing, the processor loads an operating system program.

10. The booting display control apparatus of claim 9, wherein after the operating system program is completely loaded, the processor controls the display controller to execute the vehicle backing video display function through the display control program when the vehicle backing indicator indicates vehicle backing.

11. The booting display control apparatus of claim 9, wherein the apparatus further comprises:

an external controller, coupled to the processor chip, wherein the external controller detects vehicle backing status of vehicle backing control signal recursively, and passes the vehicle backing indicator corresponding to the vehicle backing status to the processor.

12. The booting display control apparatus of claim 11, wherein the external controller detects loading status of the operating system program recursively;

when the external controller detects that the vehicle backing status turns into vehicle backing from no vehicle backing and the operating system program is not completely loaded, the external controller reactivates the processor chip.

13. The booting display control apparatus of claim 12, wherein when the external controller detects that the vehicle backing status turns into no vehicle backing from vehicle backing and the operating system program is not completely loaded, the external controller reactivates the processor chip.

14. The booting display control apparatus of claim 13, wherein the external controller controls power or a reset pin of the processer chip via a General Purpose Input/Output (GPIO) interface to reactivate the processor chip.

15. The booting display control apparatus of claim 12, wherein the external controller controls power or a reset pin of the processer chip via a GPIO interface to reactivate the processor chip.

16. The booting display control apparatus of claim 12, wherein

when the external controller is activated and the vehicle backing indicator indicates no vehicle backing, the external controller configures a reactivation status indicator to a first status;

the external controller detects whether the vehicle backing control signal indicates vehicle backing, and detects whether the reactivation status indicator indicates the first status;

when the vehicle backing control signal indicates vehicle backing, and the reactivation status indicator indicates the first status, the external controller determines the vehicle backing status turns into vehicle backing from no vehicle backing, and configures the reactivation status indicator to a second status; and

when the vehicle backing control signal indicates no vehicle backing, and the reactivation status indicator indicates the second status, the external controller determines the vehicle backing status turns into no vehicle backing from vehicle backing, and configures the reactivation status indicator to the first status.
