PARALLEL CRC COMPUTATION WITH DATA ENABLES

摘要

Methods and devices generate cyclic redundancy check (CRC) values for a sequence of parallel words of data. The data words may have only some of the bits enabled. The input words are preconditioned, and then a common block generates a CRC remainder value. A specific preconditioning is selected based on the number of enabled bits. Additional post-processing may be performed to the CRC remainder.
