MPCC: Multi-path routing packet connect circuit for network-on-chip

Abstract

Packet Connect Circuit protocol is one of the NoC communication methods. Follow the PCC protocol, the data is transmitted in form of circuit through the route established by packet switching. However, there exists disadvantage in the traditional SPCC (single path Packet Connected Circuit, SPCC) routing algorithm whose rate of channel building will slow down when the chip is congest, resulting in the reduction of the whole communication efficiency directly. To solve this problem, this paper presented MPCC (multi-path Packet Connected Circuit, MPCC) routing algorithm to form a more efficient NoC communication structure which can brilliantly improve the efficiency of data transmission of NoC when it is crowded. The experiment shows that by the method of MPCC, the average packet delay of network decreases by 33.35% compared with S PCC routing algorithm.
