3.Results show that the novel structure can realize the logic function of an adder successfully.
5.The design of a 32×32-b multiplier by using a modified Carry-Select Adder, a 4-2 compressor, and a 4 Booth encoder is presented.
7.This paper introduces a way for designing rapid adder,and an example of 3-bit-BCD-adder is provided in VHDL,and also the simulation result in Foundation Series 3.1i is given.
8.We have done HSPICE simulation runs of the new style adder, 28-T CMOS full adder and conventional CPL style full adder.
