Abstract:

The OS of VxWorks finds wide applications owing to its good real-time performance and  flexibility,but it dose not offer a common timer.This paper designs a common timer module based on auxiliary clock on the base of analyzing of several timers by utilizing interrupt of auxiliary clock and creating time-node and node list for an accurate timer for VxWorks system in certain airborne launcher's controller.Testing results show that the common timer module realizes the ms-timer,which satisfies the requirement of accurate timer for certain airborne launcher's controller.

Key words: VxWorks;common timer;auxiliary clock
