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

[0021] The method involves related symbol interpretation:

[0022] P j : the jth task

[0023] task i : Group i task

[0024] task i P j : The jth task in task group i.

[0025] P i →P j : Task P i depends on P j .

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] An embedded operating system multi-task parallel startup optimization implementation method.

[0028] The first step: multi-task determination. Divide a series of system services into different tasks P i .

[0029] The second step: multi-task dependency analysis.

Abstract

A multi-task parallel startup optimization multitask realization method of embedded operating system, the invention is defining the powerful time-sharing processing ability of the mobile embedded CPU, as the start of the embedded operating system, parallel startup some tasks that are without correlative dependence in turn synchronously, read the file of the saving system after the essence bootstrap and startup tasks in some groups synchronously, start the tasks according to the order of the task-sign until all the tasks finish startup in the same groups, every system task can parallel startup task according to the guiding relation of the tasks, that not only save the system resource but also save the total startup time of the embedded operating system.

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 multi-task parallel startup optimization of an embedded operating system. Background technique [0002] The 21st century is the era of "mobile is king" has become the consensus of industry insiders and consumers. Recently, the alliances between computer and network technology companies and mobile communication product manufacturers have become one of the most beautiful scenes in the IT industry at the end of the century. The "mobile battle" in the new century has begun ahead of schedule. Especially mobile embedded devices such as mobile phones will surely become the main competition direction. [0003] Existing mobile embedded devices come in various styles and increasingly powerful functions, and are firmly moving towards the goal of mobile data centers. The embedded operating system also plays an important role in mob...
