A low energy encoding technique for reduction of coupling effects in SoC interconnects

In this paper, we propose a novel bus encoding scheme called LESS (Low Energy Set Scheme) to minimize the coupling effects which cause significant delay and power consumption in the on-chip interconnect. Our experimental results indicate that the proposed encoding technique saves the interconnect power-delay product up to 15% and energy-delay product up to 31% for independent 8-bit data stream. Because LESS uses a slim encoding structure, area, delay, and power penalties due to additional coding circuitry are negligible compared to benefits.
