Abstract:
A decoding circuit includes a Bose-Chaudhuri-Hocquenghem (BCH) decoder. The BCH decoder includes a Syndrome stage for generating syndromes based on a BCH encoded word, a Berlekamp-Massey (BM) stage performing a Berlekamp-Massey algorithm on the syndromes to generate Error Location Polynomial (ELP) coefficients, a Chien stage that performs a Chien search on the ELP coefficients using a Fast Fourier Transform (FFT) to generate error bits and iteration information, and a Frame Fixer stage configured to reorder the error bits to be sequential based on the iteration information. The BCH decoder decodes the BCH encoded word using the reordered error bits.
