Power-Efficient Inter-Layer Communication Architectures for 3D NoC

In this work, an efficient hybridization architecture to optimize power consumption and system performance of Hybrid NoC-Bus 3D mesh is proposed. Hybrid NoC-Bus 3D mesh is a feasible architecture which takes advantage of the short inter-layer wiring delays, while suffering from inefficient intermediate buffers. To address this issue, we propose a mechanism benefiting from a low-power congestion-aware routing algorithm for vertical communication. Our extensive simulations demonstrate significant power and performance improvements compared to a typical Hybrid NoC-Bus 3D architecture.
