Abstract

Consumption of power has become an important issue for modern COMPUTING systems [1]. Research result shows that off chip busses consumes considerable amount of power.  Researchers suggested that one effective way to reduce power consumption is to reduce bus activities [2]. Power dissipation in CMOS circuits during inactive periods (static power) has become a significant part of the total power dissipation. Transition on high capacitance busses in VLSI systems results in considerable dissipation. Various coding schemes have been proposed in literature to encode data in order to reduce the number of bus transition [3][4][5]. Few method gives tremendous result 50% reduction in I/O average power dissipation and 25% reduction in I/O average power dissipation. In this paper we derived a new coding method, which leads to extremely easy practical way, which reduces number of bus transition. In this proposed scheme all bits of communication system is considered at once, and there is no need to divide bus systems into segments. Simulation result of proposed scheme shows that our concept reduces transition activities by 24.
