Abstract(in English) | We propose a method to reduce energy consumption of array multipliers by reducing the number of signal transitions. In CMOS circuits, power consumption is caused by signal transitions. The number of meaningful signal transitions for a operation is one. Signal transitions on partial product accumulator in multipliers cause many meaningless signal transitions and consume much energy. We reduce the number of meaningless signal transitions by fixing signal on operation process. Simulation results show that 32bit array multiplier using the method consumes 33% smaller energy. We also focus on the order of fixing signals to reduce the energy consumption, and the energy consumption of the multiplier is 20% smaller. |
