Abstract:

Real network-on-chip(NoC)typically include such modules,called communication hot-spot,which have much higher traffic than the system average and easy to trigger network congestion.This paper based on 2D-Mesh topology,present a method to balance communication hot-spot by lightly adjusting interconnection structure, and construct a region-based XY-YX routing algorithm. Experimental results show that the proposed mechanism can effectively reduce communication latency and increase throughput.

Key words: NoC, communication hot-spot, adjusting structure, routing algorithm
