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

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] A kind of implementation method of embedded operating system memory image start-up optimization, its specific implementation method is as follows:

[0031] 1) On-site state detection of the operating system:

[0032] The daemon process detects whether the operating system is in the interrupt processing state. Interrupt is an important interface for the communication between the core part of the computer and the peripheral equipment. No matter what the core part is doing, if there is an interrupt, it must stop and process. After the program written for this peripheral device is executed, the work just done is resumed. In order for the computer to work properly, interrupts must be reasonably allocated to peripheral devices so that they do not conflict. And if the processor is in the interrupt state, it must first complete the interrupt task. If ...

Abstract

A memory image starting optimization realization method of embedded operating system. The invention is that saving the register content of the running operating system, the memory content of using and the corresponding states to the NOR Flash of the hardware system, transfer the memory image to the dynamic random memorizer automatically, to recover the saving state of the embedded operating system. The invention is accelerating the restarting speed of the embedded operating system dramatically.

Description

technical field [0001] The invention relates to the field of startup optimization of an embedded operating system, in particular to a method for realizing startup optimization of an embedded operating system memory image. Background technique [0002] In order to make the development of embedded system more convenient and fast, there needs to be a software module specially responsible for managing memory allocation, interrupt processing, task scheduling and other functions, which is the embedded operating system. Embedded operating system is the system software used to support embedded applications. )Wait. The embedded operating system has the basic characteristics of a general-purpose operating system, such as being able to effectively manage complex system resources, abstracting hardware, and providing library functions, drivers, and development tool sets. However, compared with general-purpose operating systems, embedded operating systems have more distinctive features ...
