【摘要】 在实时嵌入式操作系统中，VxWorks以其高可靠性、高实时性、高性能特性而著称。该文在概述它的图形用户接口WindML基础上，着重分析了WindML的事件驱动机制。该机制是一个基于C/S结构的、硬设备集中监控的、高效事件分发的机制，它充分体现了分层模块化、任务队列化、低开销强实时性的系统设计思想。更多还原

【Abstract】 In real time embedded operation systems, VxWorks has excellent fame for its high reliability, the real time characteristic and the high performance. In this paper, event-driven mechanism of WindML has been mainly analyzed, based on the UGI of VxWorks, namely WindML. The mechanism is founded on C/S structure, with centralized hardware monitoring and event-distributed mechanism, which sufficiently embodies the thinking of system design, which are modularization with hiberarchy, task queuing, low spending and superior real time trait.更多还原
