摘　　要：片上网络(Network on Chip,NoC)仿真平台的搭建及路由单元的物理级实现先要有系统级的路由单元模型.提出了二维网格拓扑结构下的NoC路由单元模型,裁剪了OSI的7层协议模型作为路由单元的通信协议,在SystemC平台下实现了建模.模型采用了改进的XY维序路由算法、虫孔交换和轮询仲裁的方法,完成数据包的路由和微片的转发,在具体结构上采用全连接开关网络作为交换开关,并在模型的每个输入端设置了四条虚拟通道提升路由单元的性能.As the most important part of NoC, the system-level modeling of router can be used to construct simulation platform of NoC or guide the realization of RTL modeling of router. This paper presents a modeling of router based on 2D- Mesh, and cuts the protocol modeling of the OSI used as the communication protocol of the router. The modeling is constructed on SystemC platform, and adopts the modified XY-dimensional routing algorithm and the wormhole switching technology and the polling arbitration, and uses the full connected switch and sets four virtual channels on input ports to improve the performance of the router.
