A Residue-to-Binary Converter for the Extended Four-Moduli Set {2n – 1, 2n + 1, 22n + 1, 22n+p}
[/vc_column_text][vc_column_text] Abstract:
This brief presents a residue-to-binary converter for the moduli set {2n – 1, 2n + 1, 22n + 1, 22n+ p}, where n is a positive integer and 0 = p = n – 2. The converter consists of three simplified 4n-bit carry-save adders (CSAs) along with a modulo (24n -1) adder. The main contribution of this brief is reducing the requirements of the proposed CSA network, which has impacted the area, delay, power and energy. Compared with four-moduli and five-moduli sets that have the dynamic range 2v(24n -1), where v = n or 2n, the proposed converter resulted in the average area, delay, power, and energy reductions of 22.7%, 9.2%, 17.8%, and 24.5%, respectively. Moreover, the throughput rate per unit area has been improved by an average of 48.7%.
