摘要:

本文提出了一种低功耗、小面积的带进位保留加法器的阵列乘法器。与传统的并行阵列乘法器相比,该加法器省去了乘法器的最后一个加法级。传统乘法器和本文提出的乘法器都是用16 T全加器综合而成。在传输门、传输函数加法器、14-T、16-T全加器中,显示出能量效率。在所提出的4x 4乘法器中,在最后一级使用Ripple Carry Adder(RCA)添加进位位而不输出,进位被给予下一个左列输入的输入。因此,所提出的乘法器显示少56个晶体管计数,然后导致功率和面积的权衡。在2.0V电源电压下,采用0.18nm工艺的乘法器比传统乘法器功耗低13.91%,速度快34.09%,能耗低59.91%。

英文摘要:

In this paper a low power and low area array multiplier with carry save adder is proposed. The proposed adder eliminates the final addition stage of the multiplier than the conventional parallel array multiplier. The conventional and proposed multiplier both are synthesized with 16-T full adder. Among Transmission Gate, Transmission Function Adder, 14-T, 16-T full adder shows energy efficiency. In the proposed 4x4 multiplier to add carry bits with out using Ripple Carry Adder (RCA) in the final stage, the carries given to the input of the next left column input. Due to this the proposed multiplier shows 56 less transistor count, then cause trade off in power and area. The proposed multiplier has shown 13.91% less power, 34.09% more speed and 59.91% less energy consumption for TSMC 0.18nm technology at a supply voltage 2.0V than the conventional multiplier.
