A Traffic Equilibrium Mapping Method with Energy Minimization for 3D NoC-Bus Mesh Architecture

摘要

Flit transmission in the vertical direction of 3D NoC (Network-on-Chip) -Bus mesh architecture just needs one hop and consumes less energy. To take advantage of that and to solve the defect of poor heat dissipation, a new traffic equilibrium and energy minimization mapping method for the architecture is proposed. The proposed method adjusts traffic among buses or layers, which provides a natural condition for heat balance in the mapping step, and ensures lower energy consumption which benefits from the characteristics of the architecture. Experimental results show that energy consumption is decreased and tradeoffs can be made between energy minimization and traffic equilibrium.
