Error correction code decoder
An ECC decoder for correcting a coded signal received, which includes a syndrome calculation and errata evaluation device to receive a code word of the coded signal for performing a syndrome calculation to thereby output a syndrome polynomial, and to receive an erasure and errata evaluator polynomial and an errata position for performing an errata evaluation to thereby output an errata and erasure value and correct the coded signal; a key equation solving device to receive the syndrome for generating an erasure and errata locator polynomial and the erasure and errata evaluator polynomial; and an errata position search device to receive the erasure and errata locator polynomial for searching and outputting the errata position. Evaluating the errata and erasure value and calculating the syndrome are performed in pipeline, thereby sharing the hardware and relatively reducing the hardware cost.
