NOC设计的目的就是从体系结构上解决片上通信的瓶颈问题和时钟问题,片上网络的每条传输路径都包含若干路由器,经过每个路由器都要消耗数个时钟周期,当网络拥塞时,包传输会产生更大的延时,因此采用合适的路由算法来达到延时、吞吐率等的平衡是关键。本文使用NIRGAM仿真器对XY和OE两种算法在4×4的MESH拓扑上进行算法研究,结果显示OE算法的吞吐率和包延时的比值是2.5358,比XY路由算法的比值2.1126大,因此OE路由算法更适用于Mesh拓扑。 The purpose of the NOC design is to address the bottleneck and clock issues of on-chip communication from an architectural perspective. Each transmission path on the on-chip network contains several routers that consume several clock cycles per router. When the network is congested, Will have greater delay, so using the appropriate routing algorithm to achieve the delay, throughput and other balance is the key. In this paper, we use NIRGAM simulator to study the algorithms of XY and OE in 4 × 4 MESH topology. The results show that the throughput of OE algorithm is 2.5358, which is larger than the ratio of XY routing algorithm 2.1126 OE routing algorithm is more suitable for Mesh topology.
