Abstract

In this paper, we propose a bus encoding scheme to minimize coupling effects which cause significant power consumption in the on-chip interconnects. The proposed bus encoding scheme consist in silencing the middle two data lines of each subset which consists of 4-bit. We present a technique to eliminate correlated switching in the 4-bit data lines and also minimize self-transitions in these data lines. Experimental results indicate that the presented bus encoding scheme reduces the number of self-transitions by 20% and it also increases the number of silent lines by 9%. In addition, it reduces the power dissipation by 46% compared Bus-Invert method.
