In this paper, the new 4-moduli set {22n, 22n+1-1, 2n+1, 2n-1} with 6n-bit DR, which is appropriate for RNS applications. An efficient algorithm for residue-to-binary conversion is derived based on New Chinese remainder theorem II (New CRT-II). Next, the converter hardware is also designed to achieve average 36.6% performance saving in terms of the Area× Delay when comparing with the latest converter with 4-moduli set under the same DR requirement.
