Research on real-time control of embedded NC system based on Windows CE 5.0

Interrupt response mechanism and the stream interface driver model of Windows CE 5.0 are introduced. In view of high real-time requirements of NC (numerical control) system, the way how to realize the real-time control of embedded NC system is elaborated from the interrupt disposal process of Windows CE. Stream interface driver is adopted to develop the driver of S3C2440A processor's timer and the real-time control of interpolation in embedded NC system is achieved.
