New power-of-2 RNS scaling scheme for cell-based IC design

Abstract

Previous scaling schemes are based on the conversion of the unpositional residue number system (RNS) digits into a positional number system via Chinese remainder theorem (CRT) or mixed-radix-conversion (MRC) and the back conversion into RNS with an associated size and speed penalty in cell-based integrated circuit (CBIC) designs. This paper presents a new scaling approach, which allows faster and more efficient schemes, because the scaling uses only RNS operations within the small word length channels.
