摘要:

本文提出了一种对μClinux进行实时改造的方案,该方案采用双内核机制,借助RTLinux的实现思想,利用内核模块的可动态加载技术,对普通μClinux进行实时性改造。实验表明,该系统实时任务的调度响应和中断延时在微秒级别,能够满足硬实时系统对时间的限制。

Abstract:

The main contribution of this paper is to present an approach to improving the real-time performance of the plain μClinux. Based on the implementation of RTLinux, our real-time system is achieved by using a mechanism of dual-kernel and making use of the dynamic module loading technique. Finally the result of our simulation shows that the real-time task's scheduling response and interrupt latency in the system is at the μs level,which meets the tim me constraint of hard realtime svstems.

Key words: (RTLinux, μClinux, real-time evaluation)
