摘要：An error correction device, an error correction program and an error correctionmethod can reduce the processing time necessary for the process of correcting errorsthat involve erasure in a reception word by using a software and hardware properly and

effectively. As an error-correcting circuit 3a for correcting errors that do not involveerasure receives a reception word that involves erasure from an RDC 2, an erasureinformation holding section 3a1 holds the erasure information and a syndrome

generating section 3a2 generates a syndrome from the reception word so that a erasurejudging section 3a3 transmits the erasure information and the syndrome to an MPU 4. Inthe MPU 4, an erasure error value computing section 4a3 and erasure correcting section4a4 correct only erasure and store the reception word that does not involve erasure inan RAM 3b. The reception word from the RAM 3b is input again to the error-correctingcircuit 3a for correcting errors that do not involve erasure by way of a data bus 6 and aswitch 5. The erasure judging section 3a3 judges the reception word as one that does notinvolve erasure and has Chien search section 3a5 and an error-correcting section 3a6correct errors.
