Modular multiplication is a very important arithmetic operation in residue-based real-time computing systems. In realizing these multipliers, ROM-based structures are more efficient for small moduli. Due to the exponential growth of ROM sizes, implementations with arithmetic components are more suitable for medium and large moduli. This paper presents a new modular multiplier that can deal efficiently with medium and large size moduli. The design of this modular multiplier that multiplies two n bit residue digits consists, basically, of a (n/spl times/n) binary multiplier, a ((n-1-k)/spl times/k) binary multiplier (k
