Soft reed-solomon decoder based on error-and-erasure reed-solomon decoder

摘要

An apparatus having a first circuit and a second circuit is disclosed. The first circuit may (i) generate a decoded codeword by decoding a first codeword a plurality of times based on a respective plurality of erasure location vectors and (ii) assert a fail signal upon each failure of the decoding of the first codeword, the decoding comprising an error-and-erasure Reed-Solomon decoding. The second circuit may (i) generate a count of the assertions of the fail signal and (ii) generate the erasure location vectors based on (a) the count and (b) a plurality of reliability items corresponding to the first codeword.
