Design and Implementation for Real-Time Property of Serial Communication Based on WINDOWS CE

A software configuration for register program based on embedded CPU is addressed in this paper with characteristics analysis of WIN CE multithread. The configuration is constructed for implementing real time of serial communication of multitask program with operating system in the field of embedded application system. Based on the configuration, the CPU and registers related with serial communication and register program method with operating system are introduced as stressed part. The testing results show that the issue of real time data communication with operating system is better soluted.
