摘　　要：片上网络作为片上系统的互联机制,解决了多核芯片扩展性、时钟同步等方面的问题。高性能片上路由器作为片上网络的核心结构,已经成为一个重要的研究课题。提出了一种基于随机路由的高性能片上路由器的设计结构,实现了虚通道技术、随机路由算法、信元反馈机制。使用Verilog完成设计,通过Modelsim软件仿真后可以证明,该路由器能够正常运行,并满足功能和时序要求,同时,使用该片上路由器的片上网络的吞吐量和平均延迟性能较好。As the interconnection mechanism of system-on-chip （ SoC）, network-on-chip （NoC） solves some problems about extendibility, clock synchronization and so on. As an important part of NoC, router-on-chip has became a very important research subject. In this paper, a kind of architecture of high performance router on chip based on random routing is proposed, and virtual channel switching, random routing algorithm and credit feedback mechanism are realized. The design is finished by Verilog. The simulatation using Modelsim software proves that the router operates in normal and meets the requirement of function and time series on chip. The throughout and average delay of the NoC using the router designed by this thesis is better.
