High-speed parallel input-output bit-sliced fault-tolerant convolvers

Abstract

A family of convolvers for high sample rate is proposed, based on the composition of subconvolvers characterized by one bit samples and by modular, regular structures decomposable in identical bit-slices. Samples are represented in parallel or in skew form and the whole circuit is a sequential circuit whose combinatorial part is an array of full adders, assuring a high sampling rate. Fault tolerance provisions are also discussed.<>
