基于Windows CE5.0的嵌入式数控系统实时性研究

Research on the real-time property of an embedded CNC system based on Windows CE 5.0

研究了基于Windows CE 5.0的嵌入式数控系统的实时性,分析了Windows CE 5.0的中断响应机制,着重阐述了中断延时中ISR延时和IST延时的测试方法,对于出现延时的原因进行了深入的分析,同时对开发高性能嵌入式开放性数控系统进行了详细探讨。

This paper deals with reaserch on the real-time property of an embedded CNC system along with an analysis of the interrupt resoponse mechanism of Windows CE 5.0 and an investigation on the interrupt architecture in Windows CE. The paper also discusses how to handle the interrupt and develop a timer-driver for the embedded CNC control system. The testing method of the ISR and IST delay as well as its causes are illustrated in the paper.
