Problems solved by technology

However, this technology only uses the image file to start, and when the image file itself is very large, it cannot be started quickly
Moreover, this technology only delays the startup of some applications, and cannot realize the rapid initialization of the hardware of the car, and its startup speed still cannot meet the requirements.

Embodiment Construction

[0042] In the present application, the segmented image files respectively stored in at least two power-off storage media are loaded into the memory in parallel. The split image file is an operating system image file split according to the number of power-off storage media. Therefore, the slow loading speed of the image file caused by the too large image file is avoided, and the loading speed of the image file into the memory is improved. At the same time, the present application divides the hardware initialization operation without dependencies into at least two jobs and submits them to the loading tool, and the loading tool processes the initialization operations of the at least two jobs in parallel. This parallel processing of hardware initialization further speeds up the speed of hardware initialization, thereby realizing the fast startup of the embedded operating system, which is simple to implement and low in cost.

[0043] Of course, implementing any technical solution ...

Abstract

The present application provides a quick-start method and device for an embedded operating system, the method comprising: parallelly loading split image files respectively stored in at least two power-off storage media into the memory, the split image The file is an operating system image file divided according to the number of power-off storage media; the hardware initialization operation without dependencies is divided into at least two jobs and submitted to the loading tool; the loading tool processes the at least two jobs in parallel Initialization operation; run the image file to complete the startup procedure. The application has fast starting speed, simple realization and low cost.

Description

technical field [0001] The present application relates to embedded systems, in particular to a quick start method and device for an embedded operating system. Background technique [0002] At present, it takes a long time to start up a relatively large operating system (OS), and these operating systems are usually applied to a desktop computer or even a multi-user environment of a server. For example, the startup time of Android, Linux, iOS, etc. is very slow and long. Operating systems such as Android, Linux, and iOS especially need to consider functions such as adding new hardware, and detect the hardware, so as to establish some tags and variables required by the operating system in the memory through bootstarp. [0003] But for embedded devices where hardware changes are rarely made, almost all hardware is confirmed. The operating system of the embedded device does not need to consider the functions of newly added hardware and detect the hardware every time it is start...
