时间片轮转

为了使强实时任务能得到及时调度，同时要兼顾到公平性原则，本文提出了一种混合式调度：软实时任务采用时间片轮转的调度算法，强实时任务是采用基于优先级的抢占式调度。

As the hard task need scheduling in time , take into account fairness , this paper presents a hybrid scheduling , the soft time tasks with round robin scheduling algorithm and the hard time tasks are based on priority preemption scheduling .
