    摘要: 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.

    摘要: A decoding device for decoding a product code and a decoding method using the same are provided. The decoding device comprises an erasure flag processor, a decoder and a confidence flag processor. The erasure flag processor determines to set a particular value or a non-particular value for each erasure flag according to a plurality of the confidence flags, wherein each symbol has a confidence flag and an erasure flag correspondingly and each confidence flag has a confidence flag value. The decoder is coupled to the erasure flag processor to correct the symbols according to the erasure flags and outputs the corrected symbols. The confidence flag processor is coupled to both the erasure flag processor and the decoder to reset the confidence flag values of the confidence flags according to the erasure flags and the corrected symbols.
