During the last few years residue number (RNS) arithmetic has gained increasing
importance for providing high speed fault tolerant performance in dedicated digital signal
processors. One factor that has limited the use of redundant RNS theory in practice is the
hardware complexity of the error checker. This paper presents a mathematical analysis of
the error correction algorithm which suggests a new design with considerably reduced
hardware complexity. A hardward architecture for a high speed pipelined error checker is …
