Problems solved by technology

In this case, as a mobile embedded device user, if you are facing a general-purpose operating system, you often cannot bear the long startup time. At the same time, for the embedded operating system, you should try to shorten its startup time so To meet the user's requirements, and the boot time has become an important factor affecting the user's product selection, therefore, a new method is needed to reduce the boot time of the embedded operating system

Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] A kind of implementation method of embedded operating system hardware image startup optimization, its specific implementation method is as follows:

[0039] 1) Program interruption status detection

[0040] ① After the embedded operating system starts normally, change the system switching status through the command line in the console, and then activate the daemon process.

[0041] ②The daemon process first checks the value of the variable representing whether the process can be suspended. If the value is not 0, it means that the follow-up work can be carried out. Next, it is judged whether the process is being executed in an interrupt. If it is not to start saving the system, if it is in If it is executed during interruption, it means that an error has occurred, and the saving operation will be canceled.

[0042] ③ Create a virtual terminal for displaying deb...

Abstract

The invention discloses a method for realizing hardware mirror startup optimization for embedded operating system, not directly ending running of embedded operating system but saving state of the running operating system together with microkernel of the operating system into the in-chip memory of a processor, directly loading at the time of startup and restoring to the running state saved. And it can remarkably speed up system booting and restart so as to remarkably raise startup speed of the embedded system and reduce the time for user to wait.

Description

technical field [0001] The invention relates to the technical field of startup optimization of an embedded operating system, in particular to a method for realizing startup optimization of an embedded operating system hardware image. Background technique [0002] In the current embedded technology, the relationship between hardware and software is getting closer and closer, and the software corresponding to the hardware is also an important part of the embedded system, and because tens of thousands of codes in the current software are manually written by people , These software need to shield the differences of different underlying hardware, and must be able to meet ever-changing application requirements, so software is more complicated than hardware, and requires more research and development costs. [0003] Since the embedded system is a system for specific applications, the hardware design of different embedded systems is often very different, and it cannot have a unified...
