Abstract
In this paper, the new four-moduli set {22n, 2n+1 - 1, 2n/2 + 1, 2n/2 - 1} for even n is introduced. This moduli set has 4n-bit dynamic range and well-formed moduli which result in increased performance of RNS arithmetic unit. Then, an efficient reverse converter is presented based on New Chinese remainder theorem2 (New CRT-II) for proposed moduli set. The converter is ROM-free and based on carry save adders and modular adders which can be efficiently implemented by VLSI circuits. The presented reverse converter for moduli set {22n, 2n+1 - 1,2n/2 + 1, 2n/2 - 1} has lower delay and hardware cost in comparison to the reverse converter of the latest introduced four-moduli set {2n - 1, 2n, 2n + 1, 2n+1 - 1} with 4n-bit dynamic range.
