Improvement of Embedded Linux Operating System Scheduling Algorithm

Xu De

Abstract

In embedded systems,the real-time scheduling algorithm performance has a direct to the real-time plays a decisive role.Therefore,this paper firstly introduces the related concepts and dispatch system real-time scheduling algorithm classification,and then discusses current common scheduling algorithm based on quality,after priority scheduling algorithm was improved,based on improved after a variety of mixed RADS algorithm meets the practical application scheduling model of real-time diversity needs.
