Novel power-delay-area-efficient approach to generic modular addition

Lookup NU author(s): Professor Said Boussakta



Modular adders are fundamental arithmetic components typically employed in residue number system (RNS)-based digital signal processing (DSP) systems. They are widely used in modular multipliers and residue-to-binary converters and in implementing other residue arithmetic operations such as scaling. In this paper, a methodology for designing power-delay-area-efficient modular adders based on carry propagate addition is presented. The binary representational characteristics of the modulus are exploited to allow the sharing of hardware in a fast modular adder topology. VLSI implementation results using 0.13-μm standard-cell technology, together with a theoretical analysis, show that this approach produces adders that offer efficient tradeoffs when compared with the fastest through to the smallest generic modular adders in the literature. © 2007 IEEE.
