Abstract

This paper presents a new fast RNS converter for the 3 moduli set of the form $\{2^n-1,2^n,2^n+1\}$. A new property of the CRT is also presented and this property is used to developa fast converter for this $3$ moduli set. The resulting implementation is based on carry-save adders and one carry-propagate adder stage, without the need for any look-up tables. The new design is faster and smaller than existing designs.
