Efficient multicasting scheme for irregular mesh-based NoCs

In this paper, a simple, yet efficient hardware-based multicasting scheme is proposed for irregular mesh-based Network-on-Chips. First, an irregular oriented multicast strategy is proposed. Literally, following this strategy, an irregular oriented multicast routing algorithm can be designed based on any regular mesh-based multicast routing algorithm. One such algorithm, namely, Alternative XY (AL+XY), is proposed based on XY routing, Experimental results show that AL+XY achieve significant reduction in power consumption and packet latency compared with existing solutions.
