ABSTRACT:
A system for computing a CRC value includes at least one memory for storing a data message, a current CRC value, and a plurality of lookup tables. The data message includes a plurality of words, with each word including a plurality of bytes. Each of the lookup tables stores a plurality of multi-byte CRC values. The system includes a processor for processing the message a word at a time. The processor is configured to update the current CRC value during processing each word based on an XOR of the word and the current CRC value, and based on a multi-byte CRC value retrieved from each one of the lookup tables.
