ABSTRACT:
An error correction code system includes an error correction code generator for generating an error correction code based on a data unit and an error detector for detecting at least one bit error in the data unit based on the error correction code. The error correction code generator includes logic circuits for generating check bits in the error correction code. The error detector includes logic circuits for identifying any data bits of the data unit having a bit error based on the error correction code. The logic circuits in the error correction code generator and the error detector are derived from group codes separated from each other by a hamming distance and having a same population count. The error correction code system may also include an error corrector for correcting error bits in the data unit.
