嵌入式Linux的实时性改进技术

Linux本身不是一个实时操作系统,但它具有源代码开放的特点。将其改造为一个实时的操作系统,已成为目前嵌入式系统应用领域的研究热点。文中详细介绍了广泛采用的几种将Linux改造为嵌入式Linux的实时性实现方法及其特点。同时阐述了操作系统实时性测试的几种方法,并对嵌入式Linux的发展趋势进行了展望。指出对一般基于Linux的嵌入式系统开发者而言,采用双内核法进行操作系统实时性改进是一种较好的方法。

Amelioration Technology of Embedded Linux Real-Time Character

Linux is not a real-time operation system,but its source code is open. So it has been the research focus in the field of the embedded system application that rebuilding Linux into a real-time operation system.This article has particularly introduced some broadly adopted method and their characteristic at the present-time that rebuild Linux into the embedded run-time Linux.And it has expounded some methods about testing operation system real-time character.Also it has expected the development of embedded Linux.At the end it pointed that twokernel method is better than other methods in rebuilding operation system run-time character for the most common developer basing on the embedded Linux system.
