Study of Improved Methods for Linux System Real-time Capabilities by Tasked Interrupt Hangdling

Min Xu

Abstract

As the application of Linux to the embedded system is more and more popular,it is regarded as a potential aspect by many users to improve Linux performance to satisfy the real-time requirement.Firstly this article analyzes the limitation of the Linux′s application to real-time system,then discusses several improved methods,at last,the article gives arise to three method to improve the prempatibility of linux kernel:tasked interrupt hangdling.This method can improve the real-time capabilities of Linux system.
