Aimed at 1750a's hardware characteristic and the task type in dcmp ofp, we adopt different stratrges according to different task type . for those periodic tasks, the fixed priority dispatching stratege is used, and for time-consuming tasks we adopt time slice dispatch stratege ( round robin ) . rtos-1750 also provides binary semophor, message queue and shared memory for task to commulicate 根据1750acpu的硬件特点和dcmpofp软件的任务类型,对不同的任务采用了不同的调度策略,即对前台的周期任务采用了固定优先级调度策略,对于后台的计算类任务则采用时间片轮转调度策略(roundrobin)。
