Design and Implementation of RS (32, 28) Encoder and Decoder Using Cellular Automata

Abstract

RS (32, 28) code is popularly used for compact disk player. In this work, a modular architecture of RS (32, 28) encoder and decoder employing the regular structure of Cellular Automata (CA) has been proposed. The work also identifies a mistake in an existing related work and recti- fies it for locating double errors. The proposed CA based double error correcting codec can be easily extended to 3, 4, 5 byte error correcting codes. CA-based VLSI design is attractive because of its simplicity, regularity and higher throughput.
