嵌入式Linux操作系统实时性的研究与实现

The Research and Realization of Embedded Linux Operating System’s Real_Time Feature

本文通过研究影响linux实时性因素的几个方面,提出了对linux实时性改进的关键技术,并分别从外部实时性扩展、软中断模拟、时钟机制、可抢占式内核机制等方面给出具体的实现方法,拓展了实时系统的应用范围。

This paper studies several factors affecting linux’s real_time,The paper putsfoward key technologies to improve real_time. The paper gives implement way of realization by external real_time expansion,soft_ware interruption simulation,clock machanism,pre- emptive kernel,therefore we can extend its applied field of real_time system.
