Error correction device |
摘要 |
An error correction circuit (6) includes a first error correction operation circuit (9) subjecting to error correction a code of a line of a PI system in a data block including a product code that is stored in a buffer memory (5), and a second error correction operation circuit (10) subjecting a PO-system line code to error correction. Data corrected by the first error correction circuit is transferred to the second error correction operation circuit (10) at a second syndrome calculation circuit (13) including a storage element (13bn) storing a development of a syndrome calculation. Whenever PI-system line data corrected is received, the second syndrome calculation circuit reads corresponding data from the storage element (13bn) and calculates a syndrome and overwrites the obtained value on old data stored in the storage element (13bn). <IMAGE> |
