Method and apparatus for combined encoder/syndrome computer with programmable parity level

摘要

Methods and apparatus are provided for a combined encoder/syndrome computer with a programmable parity level. In one embodiment, a circuit is disclosed that generates check symbols during an encoding operation and generates error syndromes during a decoding operation. The circuit comprises a plurality of subfilters grouped into a multiple degree polynomial filter, where the number of multiple degree subfilters is less than a maximum number of symbols of redundancy.
