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

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.
