WebA CRC is a long-division remainder. You add the CRC to the message, and the whole thing (message+CRC) is a multiple of the given CRC polynomial. To check the CRC, you can either check that the CRC matches the recomputed value, or you can check that the remainder computed on the message+CRC is 0. This latter approach is used by a lot of … WebCyclic Redundancy Check Computation: An Implementation Using the TMS320C54x 6 Algorithms for CRC Computation Bitwise Algorithm The bitwise algorithm (CRCB) is …
