The Fastest Carry Lookahead Adder
Yu-Ting Pai, Yu-Kumg Chen · 2005
Adder is a very basic component in a central processing unit. The speed of compute becomes the most considerable condition for a designer. The carry lookahead adder is the highest speed adder nowadays. In this paper, a new method for modifying the carry lookahead adder is proposed. Based on the analysis of gate delay and simulation, the proposed modified carry lookahead adder is faster than the carry lookahead adder.
