Abstract—In recent year’s low power and power aware has become a driving force in the semiconductor industry. This is due to the growth of portable electronics industry and to the growing cost of the power dissipation on buses. Because, the power dissipation related to the bus is becoming the major part of the total power dissipation in low power VLSI. The power dissipated by DSM bus is directly related to the switching activity of the coupling capacitance that exist between the bus lines and also the switching activity of the self capacitance present between the bus interconnect and the ground. In this paper we develop a new technique to reduce the switching activity of both self and coupling capacitances through encoding the data on buses.
