In this paper, we propose a new efficient reverse converter for the 4moduli set 2n, 2n 1, 2n − 1, 22n1 – 1 based on a modified Chinese Remainder Theorem and Mixed Radix Conversion. Additionally, the resulting architecture is further reduced to obtain a reverse converter that utilizes only carry save adders, a multiplexer and carry propagate adders. The proposed converter has an area cost of (12n 2) FAs and (5n 1) HAs with a delay of (9n 6)tFA tMUX. When compared with state of the art, our proposal demonstrates to be faster, at the expense of slightly more hardware resources. Further, the AreaTime square metric was computed which indicated that our proposed scheme outperforms the state of the art reverse converter.
