摘　　要：针对现有实时调度算法在实时性能上的不足,提出了一种新的实时任务分类调度算法,根据实时任务的到达情况进行分类,划分为周期任务和非周期任务,并对不同类型的实时任务使用不同的改进的实时调度算法.通过实验,证明此算法与现有实时调度算法相比,综合实时性能有了很大程度的提高.To solve the insufficiency of real-time performance in the present real-time scheduling algorithm,a new real-time task classification scheduling algorithm is proposed.According to the arrival of real-time tasks are classified,and divided into periodic tasks and non-periodic tasks,and use different improvement real-time scheduling algorithm to schedule different type of real-time task.Experiments show that classification scheduling algorithm is compared with the present real-time scheduling algorithm,has been largely improved for integrated real-time performance.
