Configurable, fast, 32-bit CRC generator for 1-byte to 16-bytes variable width input data

摘要

A method and circuit for performing CRC calculations permits variable width data input. Preferably, multiple CRC calculations are performed in parallel, each CRC calculation involving a different number of data bits from the data word and terminating within one clock cycle. The CRC polynomial is preferably incorporated into the hardware for each CRC calculation.
