摘　　要：目前对嵌入系统的引入和应用,已越来越成为广大科研人员关心的问题。而嵌入式操作系统是嵌入系统应用的核心,文中主要探讨了源代码开放的嵌入式操作系统μC/OS的内核运行机制。首先分析任务块的基本结构,然后阐述了任务管理的实现过程,最后着重讨论了任务启动过程以及在两种不同情况下的任务切换工作原理,为嵌入式系统开发应用提供指导作用。Nowadays it has already become a noticeable problem for many scientific researchers to introduce and apply the embedded operating system. And the embedded operating system is the core of the embedded application, Operation mechanism of the emmedded operating system μC/OS is mainly described in this paper. Firstly,analyses the fundamental structure of task control block, Secondly,expatiates on the realization of task management. Finally,dicisses the process of task start and both of the task- switeh＇s operation principle in detail. Therefore it will provide good help for the researcher of the embedded operating system.
