Abstract: For the Network-on-Chip (NoC) with virtual-output-queue router architecture, a design method to customize the buffer size for each virtual channel was proposed, so that the NoC communication performance was improved. With the restriction of limited buffer resources that could be used in NoC, the effect of virtual channel buffer size on the average packet latency in NoC was analyzed, and then a buffer allocation algorithm was proposed and buffer resources were allocated to the bottleneck of NoC. It thus improved the NoC performance without additional buffer resources cost. Finally, the effectiveness of the optimization design method was validated by simulation and the performance of NoC with optimized router was compared with the performance of NoC with un-optimized router.
