摘　　要：主要研究了嵌入式系统中实时多任务的机制。通过与传统系统的比较,对实时多任务嵌入系统机制和性能作了综合描述,对其应用进行划分,并给出了抢占式和时间片循环调度式两种实现机制和实现情况。最后针对特殊的应用系统,提出一种实现这种实时多任务机制的具体方法。在嵌入式系统应用规模不断扩大的情况下,具有很好的实用价值。Mainly Studies the realization of the realtime multitasking technology.Compared with the traditional system,the embedded system is described detailed on the mechanism,performance,and classification.It introduces the preemption mode and time slice circular scheduling mode and gives the realization.Then a particular way is applied to one of such special embedded system.And it has exactly great value as the embedded system is used widely.
