Device and method for generating error correction code

摘要

A device for generating an error correction code for DVD block data including data units represented by symbols arranged an array of rows and columns. A PO calculation circuit.sequentially reads data for the symbols for each column to calculate an outer code parity. A PI calculation circuit acquires the data for the symbols read by the PO calculation circuit to intermittently calculate an inner code parity for each row. A temporary memory temporarily holds the calculation result of the PI calculation circuit.
