【Abstract】 This paper introduces the characteristics of real-time operation system(RTOS) and multi-task environment about VxWorks.Based on the analysis of SINS theory,it provides the principles to decompose the system into tasks,and introduces the tasks’ priorities and starting-up method.In the meanwhile,it brings forward the method of communication and synchronization between the tasks.At last,it offers an instance of SINS software developed by RTOS VxWorks based on the embedded computer PC-104.更多还原
