Abstract:
A compression engine calculates replacement CRC codes, in predetermined data lengths, for DIF-in cleartext data including cleartext data and multiple CRC codes based on the cleartext data. The compression engine generates headered compressed-text data in which a header including the replacement CRC codes is added to compressed-text data in which the cleartext data is compressed, and generates code-in compressed-text data by calculating multiple CRC codes based on the headered compressed-text data to add the calculated CRC codes to the headered compressed-text data.
