Abstract

Residue Number Systems (RNSs) are integer systems that enable parallel execution of arithmetic operations. Therefore, they find a wide range of applications in DSP-oriented designs. Fundamental for making RNSs usable in portable systems is the availability of power-efficient residue-to-weighted (R2W) converters. In this paper we propose an implementation of a unit of this kind, based on the precomputation optimization paradigm, that shows a 27% reduction in average pourer dissipation with respect to an existing R2W architecture specifically designed to handle a 5-moduli RNS. The area and delay penalties are kept under control in the re-designed component
