Abstract

Cellular Automata(CA) based VLSI implementation of t-byte errors correcting code has been established by previous research to be superior to the other existing techniques employed for realizing Reed-Solomon(RS) code. However, the scheme suffers from the limitation that it can correct t茂戮驴byte errors (t茂戮驴 2) provided errors are confined either wholly to the information bytes or entirely to the check bytes. The work reported in the present paper overcomes this limitation and corrects the errors likely in both information and check bytes. Moreover one weakness found in an earlier similar work has been identified and rectified using a modified check symbol expressions.
