分析其实时多任务软件设计。在介绍通信服务器功能结构的基础上，详细分析了系统的功能模块划分、数据流向、多任务划分、任务优先级确定、任务间通信方式的确定以及软件的编码测试过程。软件设计过程充分考虑通信服务器本身的特殊性，同时利用VxWorks多任务抢占式调度和时间片轮转调度的特性，以及丰富的任务间通信机制，有效地保证了系统的实时性。-Analysis of real-time multi-tasking software design. In introducing the communication server based on the structure of a detailed analysis of the function of the system modules, data flow, multi-task division, task priority identification, the task of inter-communication as well as software code to determine the testing process. Software design process itself fully into account the specificity of communication servers, while the use of VxWorks multi-tasking preemptive scheduling and time slice scheduling rotation characteristics, as well as a wealth of inter-task communication mechanisms, effectively ensure the system' s real-time.
