Abstract :
A novel parallel-prefix architecture for high speed module 2n -1 adders is presented. The proposed architecture is based on the idea of recirculating the generate and propagate signals, instead of the traditional end-around carry approach. Static CMOS implementations verify that the proposed architecture compares favorably with the already known parallel-prefix or carry look-ahead structures
