随着ARM处理器计算能力的提高，该类型的处理器在嵌入式领域的应用越来越广泛的同时，也得到了数控系统的青睐。结合数控系统的实时加工技术的要求，通过分析和研究Linux实时抢占补丁( RT-Preempt patch)技术，提出了一种基于ARM微处理器TI AM3358的嵌入式实时系统解决方案。在以TI AM3358为硬件平台的Linux嵌入式系统中实现了RT-Preempt的应用，并对任务调度延迟、中断响应延迟和优先级反转问题进行了测试。经试验证明，提出的实时系统解决方案可以满足中档数控系统实时加工的需求。

With the increase in computing power of ARM processor, this type of processors are used more and more widely in embedded field, at the same time, they are favored by the CNC system. Through analy-sis and study of the Linux real-time preemption patch ( RT-Preempt) presented a new embedded real-time system solution based on ARM microprocessor TI AM3358 and RT-Preempt. Finally, this paper completed the measurement of task schedule latency, interrupt response delay and priority inversion problem which af-fect the performance of real-time system. The results of the experiment support that the performance of that solution can meet the demand of real-time processing from CNC.
