摘　　要：多处理器实时调度理论是目前实时系统的关键技术。论文研究了PFair调度算法在多处理器中的调度理论,在此基础上,提出了一种基于PFair调度算法的处理器分组调度算法。该算法通过对处理器分组,降低了PFair算法中存在时间消耗过大的问题,从而有效的提高了整个系统的性能。The real-time scheduling theory is a key technology in muhiprocessor systems, in this paper some scheduling theories of PFair are studied and a packet processor scheduling algorithm based on PFair for muhiprocessors is presented. This algorithm reduces the consumption of time and improve effectively the performance of the whole system by packing processors of the system.
