Design of Mutli-Serial Communication System Based on VxWorks

The characteristic performance of embedded real time operating system VxWorks was introduced.The exploitation method of embedded system unit drivers and the exploitation technique of VxWorks were analyzed.As well as the hardware framework of the multi-serial communication system was introduced and the software was designed.Some parts of interrupt service routine example code were given.Through system test and analy-tic result,the multi-serial communication system showed good reliability and real time performance.
