【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%。
[Abstract]:In order to make full use of the parallel communication ability of the on-chip network and exploit the bandwidth utilization of the network, a high performance dual-port on-chip network is designed. Each routing node in the network provides two local ports, and each resource node is diagonally connected to the two routing nodes in the network. For this access structure, a method of switching the destination nodes is proposed to improve the parallel communication capability of the network. At the same time, in order to improve the performance of the new routing architecture, the dual-port routing node is introduced into the Torus structure, and the model of dual-port network based on Torus is constructed, and its performance is evaluated. The experimental results show that, The diagonal dual-port NoC based on Torus structure can improve the average throughput and average packet delay of single-port network by 83.3% and 55.9%, and the average throughput and average throughput of dual-port network with the same dimension sequence in binocular experiment are improved by 83.3% and 55.9%, respectively. The average packet delay improved by 91.1% and 54.3%.
