Low Latency Multicasting Scheme for Bufferless Hybrid NoC-Bus 3D On-Chip Networks

In this paper, we proposed a novel multicast routing algorithm for the 3D Bufferless Hybrid Interconnection Network to enhance the overall system performance. The proposed algorithm makes use of a single-hop and broadcast (bus-based) interlayer communication of the 3D NoC-Bus mesh architecture. Compared to the DRM_noPR multicast routing algorithm, our simulations with six different synthetic workloads reveal that our architecture using the proposed multicast routing algorithm acquires high system performance.
