摘　　要：介绍了基于TMS320VC5402的新型微机保护核心平台的硬件系统,及μC/OS-Ⅱ在TMS320VC5402上的移植。将实时多任务系统和传统的前后台系统进行了比较,最后阐述了其基于μC/OS-Ⅱ多任务实时操作系统的软件设计思想,尽量使软件和硬件脱离,把整个系统分成几个任务,然后赋予每个任务唯一的ID号,并对各个任务指定其优先级。进入运行状态后,在主任务中启动其他任务,在这些任务中又可以启动另外的任务。The hardware system of a product platform for microcomputer protection system based on TMS320VC5402 is put forward. The transplantation of μC/OS -Ⅱ to TMS320VC5402 is intro,duced as well. The multi,task RTOS(Real,Time Operating System) is compared with the front,back system. The software design idea based on μC / OS -Ⅱ multi,task RTOS is explained,that is,sepa,rate software from hardware,divide the system into several tasks,afford each task an exclusive ID and appoint its priority. During running state,tasks may be initiated by main task and other tasks.
