Abstract :
In this paper, two topology oriented multicast routing algorithms, MXYZ and AL+XYZ, are proposed to support multicasting in 3D Networks on Chips (NoCs). In specific, MXYZ is a dimension order multicast routing algorithm that targets 3D NoC systems built upon regular topologies, while AL+XYZ is applicable to NoCs with irregular topologies. If the output channel found by MXYZ is not available (i.e. in the same region), an alternative output channel is used to forward/replicate the packets in AL+XYZ. MXYZ is evaluated against a path based regular topology oriented multicast routing and AL+XYZ against an irregular region oriented multiple unicast routing algorithm. Our experimental results have demonstrated that the proposed MXYZ and AL+XYZ schemes have lower latency and energy consumption than the conventional path based multicast routing and the multiple unicast routing algorithms, meriting them to be more suitable for supporting multicasting in 3D NoC systems.
