In this paper, a novel hardware support for multicast on mesh Networks-on-Chip (NoC) is proposed. It supports multicast routing on any shape of tree-based paths. Two power-efficient tree-based multicast routing algorithms, Optimized tree (OPT) and Left-XY-Right-Optimized tree (LXYROPT) are also proposed. XY tree-based (XYT) algorithm and multiple unicast copies (MUC) are also implemented on the router as baselines. Along with the increase of the destination size, compared with MUC, OPT and LXYROPT achieve a remarkable improvement in both latency and throughput while the average power consumption is reduced by 50% and 45%, respectively. Compared with XYT, OPT is 10% higher in latency but gains 17% saving in power consumption. LXYROPT is 3% lower in latency and 8% lower in power consumption. In some cases, OPT and LXYROPT give power saving up to 70% less than the XYT.
