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 … WebNov 6, 2024 · CRC Software Accelerator.
