Abstract

In this paper, we firstly propose an on-chip bus power consumption model, which includes the self transition power dissipated on the signal lines and the coupled transition power dissipated between every two signal lines. And then a new heuristic algorithm is proposed to determine a physical order of signal lines in bus. Experimental results show an average power saving 26.85%.
