中文摘要:
      为了充分利用片上网络的并行通信能力,挖掘网络带宽利用率,设计了一种高性能的双端口片上网络。该网络中每个路由节点提供两个本地端口,每个资源节点采用对角线的方式接入到网络中两个路由节点上,并针对这种接入结构提出一种目的节点切换方法用于提高网络的并行通信能力。同时,为进一步提高新路由结构的性能,将双端口路由节点引入Torus结构,构造了基于Torus的双端口网络的模型,并对其进行性能评估。实验结果表明,基于Torus结构的对角线双端口NoC在单目事物实验中较单端口网络平均吞吐量和平均包延迟最大改善了83.3%和55.9%,在双目事物实验中较同一维序双端口网络平均吞吐量和平均包延迟最大改善了91.1%和54.3%。
英文摘要:
      In order to take full advantage of Network on Chip parallelism ability and improve network bandwidth utilization, a high performance dual port network is introduced in this paper. Each router in the structure provides two local ports, and each resource node connects with two routers in a diagonal. A destination node switching method is proposed in this structure to improve the parallel communication ability of network. Meanwhile, to further improve the performance of the network, the Torus structure is introduced to reduce the network radius. This paper builds a model of dual port network, and evaluates its performance. Compared with signal port network, the experiment results show that the structure can improve the average throughput and the average latency by 83.3% and 559% at best in unary affairs. Compared with the same dimension dual port network, the experiment results show that the structure can improve the average throughput and the average latency by 91.1% and 54.3% at best in binary affairs.
