Problems solved by technology

The signal to open the car door is used as a signal to start the operating system, but it does not fundamentally increase the startup speed of the operating system. The core still needs to read the startup program sequentially from the flash memory, and then run the program after all the programs are loaded, causing the operating system to start slowly.

Embodiment 1

[0027]figure 1 A flow chart of an operating system startup method for the embodiment of the present invention, the present embodiment can be applied to the case where the automotive operating system is activated, and the method can be performed by the operating system start device, which specifically includes the steps of:

[0028]S110, when the ignition operation of the automobile engine is detected, the load task corresponding to each core is obtained by at least two cores.

[0029]In general, due to flash self-electrical characteristics and file system restrictions, the core can only read the content into the memory, and all applications can be performed in all applications, and the launching program is low, and the car cannot be Quickly start, the user's waiting time is long, reducing the user's experience.

[0030]At least two cores are configured in the chip and configure at least one flash memory for each core. When the ignition operation of the automobile engine is detected, each cor...

[0053]Among them, the load task acquisition module 310 is loaded, and after detecting the ignition operation of the automobile engine, the loading task corresponding to each of the cores is obtained by at least two cores; the program load module 320 is used to give each core, according to the core The loading task loads the target startup program from the flash memory corresponding to the core; the program running module 330 for each core, and when the target startup program is completed, the core runs loaded the target launching program, Start the operating system.

[0054]Optionally, load tasks include saving addresses and program categories to be loaded;

[0055]In the technical solution of the above embodiment, the program load module 320 inc...

Abstract

The embodiment of the invention discloses an operating system starting method and device, equipment and a medium. The method comprises the following steps: after ignition operation of an automobile engine is detected, obtaining a loading task corresponding to each core through at least two cores; for each core, loading a target starting program from a flash memory corresponding to the core according to the loading task; and for each core, when the loading of the target starting program is completed, the core running the loaded target starting program so as to start the operating system. According to the technical scheme, the problems that a mirror image starting mode of the automobile operating system does not have universality, and when the operating system is started in cooperation with an external controller, a core still needs to sequentially read starting programs from a flash memory and then run the programs after all the programs are loaded, so that the operating system is started slowly are solved; the quick starting of the automobile operating system is realized, the starting efficiency is improved, and the waiting time of a user is shortened.

Description

Technical field[0001]Embodiments of the present invention relate to the technical field of operating systems, and more particularly to an operating system startup method, apparatus, apparatus, and medium.Background technique[0002]In the automotive industry, after the engine is ignited, the start time of the instrument has more strict requirements. At present, the industry is basically required to enter the system's normal working condition after 3S after ignition.[0003]At present, the main method in the automotive is the micro-nuclear operating system. It has two main methods for improving the operating system startup speed: using the mirror start mode, starting from the static memory, avoiding the process of copying system mirroring from static memory to memory Or when the door is opened, the signal transmitted by the door controller as a flag, start the operating system in advance, silently runs, and directly open the screen directly, the user generates a rapid feeling of startup....
