摘要：In Deep-submicron (DSM) systems, the coupling effect on onchip data buses and interconnects plays an important role in overall performance and reliability of the VLSI systems. In many digital processors and SoC the switching activity results into dynamic power dissipation on the data buses and interconnects which is a major part of the total chip power dissipation. Switching activity is due to self transitions and coupling transitions. Reducing the power dissipation of the VLSI chip is one of the major challenges in the DSM technology. One of the best techniques to reduce the transitions is to encode the data on the data bus. Hence an efficient switching activity reduction technique is proposed which can reduce the overall transitions. The proposed encoding technique reduces the coupling transition by 29% to 33%, self transitions by 4% to 19% and overall transitions by 22% to 27%. Its efficiency is 10% to 17% more compare to others encoding techniques.
