Fault-tolerance scheme for an RNS MAC: performance and cost analysis
A.P. Preethy, Damu Radhakrishnan, Amos R. Omondi · 2002
Residue number systems (RNS) are especially useful in applications in which fault-tolerance is a requirement. Accordingly, this paper discusses a novel and elegant fault-tolerance scheme incorporated into a multiply-accumulate (MAC) unit based on RNS. The fault-tolerance is achieved by using inexpensive forward conversion procedures. The cost and performance are analyzed with respect to other designs, and the analysis indicates superior cost:performance measure for our design.
