摘要
本文针对如何在有效利用Linux能够方便地移植到不同应用平台的优势的同时,使其能够满足实时应用的要求,对Linux-2.6.9核心进行了改造。首先,通过RED-Linux项目,在实时硬件抽象层(RTHAL)上建立实时应用借口(RTAI),在新内核Linux-2.6.9-adeos上实现了RTAI,并进行了任务切换延迟、实时程序和普通程序三种测试;最后对RTAI、RTL inux两种改造方案进行了比较。
To make use of the advantage of being easily migrated on different application flat ports of Linux, and satisfy the real-time demand as well, the real-time ability of Linux 2.6.9 kernel was improved. Firstly, construct the RTHAL, on which the RTAI was based, and the new kernel was tested by task-delay program, real-time program and user program. At last, the two methods of RTAI and RTLinux were compared.
