Abstract
Apparatus and an associated method calculates a CRC remainder for a block of data, such as a block of data retrieved from a CD-ROM device. CRC calculations are performed to provide assurances of data integrity subsequent to error corrections of the block of data. CRC remainders associated with N powers of two are stored in the look-up table. When calculating the CRC remainder, selected values stored in the look-up table are retrieved and combined to form the CRC remainder for the block of data.
