Abstract
This paper introduces the design method of parallel adder. On the basis we design an adder by the adoption of carry skip algorithm with carry strength signals and implement,through logic synthesis and layout. Analyses and comparisons show this addet is better than carry lookahead adder in speed,power dissipation and area.
