In modern digital circuits the total power attributed to wires is increasing. Reducing the power consumption in wires play a major role in low power design. Coupling transitions contribute to significant energy loss in deep sub-micron buses. Earlier schemes using the switching activity minimization based upon the substrate capacitances are not valid in these buses. Hence, a new low energy bus-encoding scheme is proposed which showed 10 % reduction in coupling transitions for 8 and 16 bit data.
