Power optimization for application-specific 3D network-on-chip with multiple supply voltages
Kan Wang, Sheqin Dong · 2013
In this paper, a MSV-driven power optimization method is proposed for application-specific 3D NoC (MSV-3DNoC). A unified modeling method is presented for considering both layer assignment and voltage assignment, which achieves the best trade-off between core power and communication power. A 3D NoC synthesis is proposed to assign network components onto each layer and generate inter-layer interconnection. A global redistribution is applied to further reduce communication power. Experimental results show that compared to MSV-driven 2D NoC, the proposed method can improve total chip power greatly.
