| Abstract: | Two definitions of carry propagation function and basic circuit unit and three combination scenarios of Carry Lookahead Adders(CLA) were analyzed for resource (area ), speed and power dissipation in this paper. The optimizing design of basic circuit unit and combination scenarios was completed and some optimizing method of combination circuit was given . Those laid a foundation for the structure design optimizing of CLA. |
