摘　　要：针对设计片上网络仿真平台的需要,提出了1种应用于2D-Mesh拓扑结构的片上网络路由单元的系统级模型,该模型提供东西南北与本地5组输入输出通道,采用了无死锁的XY维序路由算法。模型对数据包采用存储转发的方式,输入端获得数据包后提取包头中的目标地址信息,根据路由算法确定转发方向,并优先保证GS包的发送。建模平台选用SystemC,并在该平台下进行了验证。结果表明,所设计的片上网络路由单元模型能够实现数据包的并行发送,并支持GS服务。This paper presents a system-level model of the router of Network on Chip （NoC） based on 2D-Mesh out of the need of the simulation platform in NoC. The modeling provides 5 groups of input and output ports in all directions and adopts the XY dimensional order routing algorithm without locking. This model employs the storage and transmitting to treat the data packets： the input port picks up the destination address in the head ＇after the data packets are obtained, then establishes the output port through the routing algorithm and ensures the output of GS packets. The modeling is constructed on the SystemC platform, where the certification is also finished. The result shows that the modeling of the NoC router is able to perform the simultaneous transmitting of the data packets and support the GS service.
