Single-chip parallel processing requires high bandwidth between processors and on-chip memory modules. A recently proposed Mesh-of-Trees (MoT) network provides high through put and low latency at relatively high area cost.In this paper, we introduce a hybrid MoT-BF network that combines MoT network with the area efficient butterfly network. We prove that the hybrid network reduces MoT network's area cost. Cycle-accurate simulation and post-layout results all show that significant area reduction can be achieved with negligible performance degradation, when operating at same clock rate.
