BINARY TO RNS ENCODER FOR THE MODULI SET {2n−1,2n ,2n+1} WITH EMBEDDED DIMINISHED-1 CHANNEL FOR DSP APPLICATION

Architecture of binary to residue number system encoder based onthe moduli set {2n − 1,2n,2n + 1} with embedded modulo 2n + 1 channel in the diminished-1 representation, which can be used instead of the standard modulo 2n+1 channel, is presented. We consider the binary numbers with dynamic range of proposed moduli set which is 23n−2n. Within this dynamic range, 3n-bit binary number is partitioned into three n-bit parts and converted to residue numbers. The proposed architecture based on moduli set {2n−1,2n ,2n+1} with embedded diminished-1 encoded channel have been mapped on Xilinx FPGA chip. The proposed architecture can be utilized in conjunction with any fast binary adder without requiring any extra hardware
