摘　　要：针对标准Linux实时性不足的问题,结合数控系统的实时性要求,提出了基于Xenomai的Linux系统实时性改造方案,完成基于Xenomai的Linux域设计。进行实时化内核的移植,借助s3c2410芯片创建实时系统,最后进行了实时任务调度延迟测试、内核定时器中断延迟测试。实时性能指标测试验证了基于Xenomai的Linux实时性改造方案在数控系统中的可行性。To the problem of lack of real time for standard Linux, combined with the real time requirements of CNC system, a real time reconstruction scheme of Linux system based on Xenomaiis put forward. The porting of Linux domain and real time kernel based on Xenomai is completed, and the s3c2440 chips are used to implement this real time system. Finally, real time task latency test are used to verify the feasibility of Xenomai based Linux real time is satisfied.
