摘要

基于进位选择加法器中共用两个加法器的思想，提出了一种低功耗高性能加法器的新设计。新的加法器比纹波进位加法器(RCA)快，但比CSA慢。另一方面，它的面积和功耗比CSA小。

Closing the gap between carry select adder and ripple carry adder: a new class of low-power high-performance adders

Based on the idea of sharing two adders used in the carry select adder (CSA), a new design of a low-power high-performance adder is presented. The new adder is faster than a ripple carry adder (RCA), but slower than a CSA. On the other hand, its area and power dissipation are smaller than those of a CSA.
