http://www.quviq.com/checksum-property-for-autosar/ WebThe CRC algorithm operates on a block of data as a unit [ 1 ]. We can understand the CRC better if we see a block of data as a single (large) numerical value. The CRC algorithm divides this large value by a magic number (the CRC polynomial or generator polynomial), leaving the remainder, which is our CRC result.
