| Zusammenfassung: | An error correcting apparatus includes a storing means for storing product code with n2 rows and n1 columns, an error correcting unit 5 that performs error correction for four code sequences simultaneously in parallel, and a bus control unit 2 for reading codes on four rows from the buffer memory 1 and transferring the codes to the error correcting unit 5. The bus control unit 2 reads and transfers four consecutive codes on each of four rows in order before shifting the reading position by four codes in the row direction. |
