一种环形Buffer自适应NoC路由器设计

Design of a Ring Buffer Adaptive Router for Network-on-Chip

摘要: 在片上网络（Network-on-Chip，NoC）系统中，对路由器缓存进行有效的设计及管理，能够有效提高系统多方面的性能.设计了一种环形缓冲结构的自适应路由器，该路由器中所有通道的缓冲资源相互连接形成一个封闭的环，繁忙的输入通道能够共享其他通道的空闲缓冲资源.2D M esh网络中的实验结果表明，环形缓冲结构的路由器与传统路由器相比，能量消耗得到了降低，缓冲使用缩小了5倍.此外，大量的仿真研究表明，该路由器结构提高了网络性能，减少了平均信息延时.

Abstract: In the system of the Network-on-chip (NoC),design and management of router cache can improve performance of system effectively in many aspects.This paper designed a ring buffer adaptive router.In the router of ring buffer structure,buffer resources of all channels are connected to each other,and form a closed ring,when an input channel is busy,it can share the free buffer resources of other channels.Implementation results show that energy consumption has been reduced,buffer using reduces 5 times when compared with a traditional router in 2D Mesh network.In addition,a large number of simulation studies show that the router improves the network performance,and reduces the average message delay.
