Abstract
An error correction circuit includes a first error correction operation circuit 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, and a second error correction operation circuit 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 at a second syndrome calculation circuit including a storage element 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 and calculates a syndrome and overwrites the obtained value on old data stored in the storage element.
