摘要
从体现资源 (面积 )、速度、功耗的各个方面分析了超前进位加法器进位传输函数的 2种定义和基本单元电路及其 3种组合方案 .完成了基本单元电路及其组合方案的优化设计并给出了组合电路的一些优化方法 .
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.
