ERROR CORRECTING CODE (ECC)

When disc data is damaged, it is corrected using the ECC (Error Correcting Code) block. It uses the CIRC (Cross

Interleaved Reed-Solomon Code), correcting up to 2 errors when C1 (32, 28), and up to 4 erasures when C2 (28,

24). Error correction handles the data in units of 8-bit 1 symbol.

The ECC block has Pointer handling function, and can generate a C1 pointer in C1 correction, and a C2 pointer in

the C2 correction. The C1 and C2 pointers output a flag about the ECC-handled data to mark it as error data. This

Flag information signal is input into the interpolator, and used for handling the error data. Also, the Error correcting

results can be monitored using the FLAG1, FLAG2, FLAG3, FLAG4, FLAG5 pins
