Network-on-Chip multicasting with low latency path setup

A low-latency path setup approach with multiple setup packets for parallel set is presented. It reduces the header overhead compared to multiaddress encoding. Further, we propose four variants of deadlock-free multicast routing algorithms using different subpath generation methods, different destination partitioning, and channel sharing strategies. Experimental results show that the quatuor partitions path-like tree outperforms other algorithms.
