摘要： 提出一种片上网络带宽资源QoS调度算法。通过分布式地动态调整有保障服务(GS)连接在每个路由器中的优先级，解决共享同一物理链路的不同GS连接之间的传输冲突问题，从而保障时延、带宽和时延抖动等QoS。通过给尽力而为服务(BE)通道分配动态优先级和监控GS流量2种方法的应用，有效提高了BE数据流的服务质量及链路利用率。

Abstract: This paper proposes a QoS schedule algorithm for bandwidth in NoC to solve traffic conflicts between different Guaranteed-Services (GS) connections which share the same physical link. By dynamically allocating priorities of these GS connections respectively, this algorithm can guarantee such QoS requirements as bandwidth, latency and zero jitter. It improves QoS and link efficiency of Best-Effort(BE) data flow significantly by allocating dynamic priorities to BE channels and monitoring GS traffic.

Key words: Network-on-Chip(NoC), schedule algorithm, Quality of Services(QoS)
