CRC CRC check consists of two modules CRC State machine Check the input if header data or trailer frame Compare the trailer crc with the generated crc Keeps the crc error counter MDC CRC State machine CRC Generator Generate the CRC from the Data frames Use a MIT hardware generator for the logic http://outputlogic.com/?page_id=321 CRC generator Institut f r Technik der Informationsverarbeitung Fu zeile ( ndern ber "Einf gen" / "Kopf- und Fu zeile") Datum 2
