Architectural Design of CA-Based Double Byte Error Correcting Codec

Cellular Automata (CA) is a novel approach for designing byte error-correcting codes. The regular, modular and cascaded structure of CA can be economically built with VLSI technology. In this correspondence, a modular architecture of CA based (32, 28) byte error correcting encoder and decoder has been proposed. The design is capable of locating and correcting all double byte errors. CA-based implementation of the proposed decoding scheme provides a simple cost effective solution compared to the existing decoding scheme for the Reed-Solomon (RS) decoder, having double error correcting capability.
