Power-delay-area efficient modulo 2/sup n/+1 adder architecture for RNS

A new modulo 2/sup n/+1 adder architecture based on the ELM addition algorithm is introduced. A simplification to an existing modulo 2/sup n/+1 addition algorithm is also presented. VLSI implementations using 130 nm CMOS technology demonstrate the superiority of the proposed adder over existing designs in the literature.
