Apparatus and method for correcting data errors

摘要

A partial circuit of an encoding circuit for realizing a first error correction encoding algorithm and a partial circuit of an encoding circuit for realizing a second error correction encoding algorithm are shared to realize these two algorithms by one error correction encoding circuit. A partial circuit of a decoding circuit for realizing a first error correction decoding algorithm and a partial circuit of a decoding circuit for realizing a second error correction decoding algorithm are shared to realize these two algorithms by one error correction decoding circuit. A plurality of error correction encoding algorithms can therefore be realized by a simple and inexpensive circuit.
