摘　　要：针对传统总线系统架构的缺点,为提高多核系统性能,设计了一个2D-Mesh Network-on-chip(NoC)片上网络,通过片上网络中的路由器来连接芯片上的各个处理器核,实现核间通信.2D-Mesh拓扑结构、电路交换技术和XY路由算法保证了系统的延迟和吞吐量,硬件设计语言Verilog HDL物理实现NoC.利用Altera公司的FPGA开发板对本文设计的片上网络NoC进行测试,测试结果表明本文所设计的片上网络是正确的,能有效的完成系统通信.Considering the shortcomings of the traditional bus system architecture,in order to improve the multi-core system performance,Mesh Network-on-chip(NoC)is designed in this paper.Processor core on the chip links each other through the routers in the NoC,and the communication between nuclears are implemented.The 2D-Mesh topology structure,circuit switching technology and XY routing algorithm can guarantee the delay and throughput of the system,and hardware design language Verilog HDL achieved physical NoC.The FPGA Development Board of Altera company was used to test the NoC,the test result shows that this design on the NoC is correct,and can complete system communication effectively.
