本文简要介绍了实时操作系统的概念，对RTAI 与LINUX 相结合的双内核硬实时操作系统进行了深入的研究，设计了基于双内核的通用实时操作系统的结构框架。并实现了高速数据采集卡、光纤卡、多串口等硬件的LINUX 实时高速驱动，并在实时控制平台上实现了相关控制和仿真算法。最终在此基础上开发了基于UNIX/LINUX 的高速硬实时控制软件，试验表明其具有较高的运行效率。关键词：硬实时 LINUX RTAI 双内核Abstract: This paper comes up with a general real-time software architecture based onLINUX&RTAI which is designed to implements hard real-time operations and soft real-timeoperations simultaneity in RTAI-CORE and LINUX-CORE. And finally establish high-speedreal-time control software based on a general real time software architecture, and the design wasproved by experiments that it is efficient.
