Application of RTOS VxWorks in data link system

In order to fulfill the high real-time requirement that the data link system needs in practical design,a scheme is proposed by using an embedded system based on VxWorks.This embedded system takes advantage of the excellent real-time performance,multi-task scheduling technology of VxWorks and the modularized and layered designing concept.A model which based on the double-buffering message queue and semaphore mechanism is established.By reasonable division of the task function and the priority settings of the tasks,the system designed implements the high real-time requirement in data link system.
