【摘要】 片上网络作为一种全新的集成电路体系结构,可以很好的解决随着复杂度的增加所带来的片上通信需求问题。本文提出利用 OPNET 构建片上网络高层次模型,研究拓扑结构、交换方式、通信负载以及通信模式四个参数对片上网络性能的影响,并采用平均延迟和吞吐量两项指标来评估网络性能.通过仿真结果,得出不同参数配置下的网络性能,为片上网络设计和体系结构研究提供依据。更多还原

【Abstract】 Network on Chip(NoC)is an emerging IC architecture that cope with the increasing complexity and communication requirements of current System on Chip(SoC).In this paper,we present network simulator OPNET to constructed a NoC high-level model and simulations were performed with different combinations of the network parameters(network topologies,switch techniques,traffic patterns, communication load).Detailed comparative analysis of the network performance in terms of latency and throughput are presented,which could help system designers in making appropriate choices for different network parameters in designing an NoC.更多还原
