主要介紹了一個基于Linux 操作系統(tǒng)的實時平臺的技術研究和實現方法。所研究的實時平臺以X86 體系PC 為硬件環(huán)境，Linux 操作系統(tǒng)的標準內核加載RTAI 模塊為軟件環(huán)境，可為構建實時系統(tǒng)提供優(yōu)良平臺。該平臺通過RTAI 在Linux 上定義的一個實時硬件抽
象層(RTHAL)來實現實時進程的最高優(yōu)先級調用。

The Real-Time Platform Based on Linux LI jun-ping ,mei hong , shan jia-yuan (Mechatronics Department,Beijing Institute of Technology,Beijing 100081,China) Abstract: This paper aims to make a brief study of the real-time platform based on Linux. The hardware of real-time platform is X86 PC, and the software of real-time platform is modified Linux kernel by RTAI modules .The real-time platform has been successfully applied into some practical experiment simulation control systems.
