摘　　要：针对VxWorks系统在任务间通信机制上存在的局限性,例如不支持2种最基本的通信机制—事件和邮箱机制,使得多任务多事件间的同步受到一定的限制,通信的及时性和异步性也得不到很好的实现。对比Windows的邮槽服务机制,结合VxWorks的组件开发方法,给出一种VxWorks的邮箱通信机制,并对该机制做了算法上的分析和设计。Corresponds the limitation in view of the VxWorks system in the duty which in the mechanism exists, for example does not support two kinds of most basic correspondences mechanisms event and the mailbox mechanism,causes the multi - duties during multi- events synchronization to receive the certain limit,correspondence timeliness and the asynchronous also cannot obtain the very good realization,contrasts Windows the postal trough service mechanism, unifies VxWorks the module method of exploitation,has produced one kind of VxWorks mailbox correspondence mechanism,and to this machine has manufactured in the algorithm analysis and design.
