MULTIPLIER HAVING LOW POWER CONSUMPTION

摘要

PURPOSE: A multiplier having a low power consumption is provided to minimize a power consumption by using a modified bus algorithm. CONSTITUTION: A multiplier part output unit(100) multiplies an input signal in accordance with a modified bus algorithm. A carry non-delivery adder(110) adds an output signal of the multiplier part output unit(100) to another input signal without transmitting a carry. The carry non-delivery adder(110) is constructed as a CSA tree. An adder(120) adds an output signal received from the carry non-delivery adder(110) and generates a final output. The multiplier having a low power consumption is formed by the type of a PPG, a CSA and a CPA.
