Abstract

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.
