A method of configurable decoding is disclosed. The method generally includes the steps of (A) receiving a variable value in a configuration signal, (B) calculating a plurality of first syndromes corresponding to a particular codeword of a plurality of codewords received in an input signal, the particular codeword having a plurality of information symbols and a plurality of parity symbols coded such that up to a fixed value of a plurality of errors in the particular codeword are correctable, the fixed value being greater than the variable value, (C) transforming the first syndromes into a plurality of second syndromes such that no greater than the variable value of the errors in the particular codeword are correctable and (D) generating an intermediate signal carrying the second syndromes.
