An Power Efficient New CRT Based Reverse Converter for Moduli
نویسنده
چکیده
The 4-moduli{ } set has been recently proposed for large dynamic range of 6n-bits .for this 4moduli set reverse converter design based on New CRT-1 and MRC has already been proposed. In this paper we propose reverse converter design for 4-moduli set{ }based on New CRT-II theorem to achieve more efficient residue number system(RNS) than the former one. The design is achieved using carry save adders and carry propagate adders only i.e. it is purely adder based. We implemented the proposed reverse converter design on a standard 180nm CMOS technology and when compared with the other equivalent state of art converters it has indicated about 34% better performance in terms of power. Keywords-Residue Number system (RNS) , Chinese Remainder Theorem (CRT) , Mixed Radix Conversion (MRC) , New Chinese Remainder Theorems (NEW CRTS) , Reverse converter .

Residue Number System is a kind of numerical systems that uses the remainder of division in several different moduli. Conversion of a number to smaller ones and carrying out parallel calculations on these numbers will increase the speed of the arithmetic operations in this system. However, the main factor that affects performance of system is hardware complexity of reverse converter. Reverse co...

In this paper, an efficient residue to binary converter design for the new high dynamic range moduli set {2-1,2+1,2,2+1,2-1} is presented. The reverse conversion in the four-moduli set {2, 2+1, 2+1, 2-1} has been proposed in literature. Hence, the converters are based on the new moduli set {2-1, (2-1)(2+1)(2+1)2} and propose its residue to binary converter using New Chinese Remainder Theorem 2 ...
