Thermal-aware mapping and placement for 3-D NoC designs

Abstract

Networks on chip (NoC) and 3D integrated circuits have been proposed as solutions to the ever-growing interconnect woes surrounding systems-on-chip. 3D designs however suffer from hotspot creation, due to the increase in the power density of parts of the chip. In this paper, we propose the use of a genetic algorithm for a thermal and communication aware mapping and placement of application tasks on 3D NoC environment. Our results show a significant reduction in system temperature when compared to a random mapping and placement, and provide an encouraging situation for migration to the 3D design space
