A METHOD FOR RECOGNISING THE COMMUNICATION PROTOCOL OF DATA PACKETS TRAVELLING OVER A COMMUNICATION BUS

A method for recognising a communication protocol of data packets (M1, M2) travelling over a communication bus (20). The method comprises a CRC check procedure (PCRC1, PCRC2) for processing a data packet (M1, M2) travelling over said communication bus (20), said CRC check procedure comprising: - cal...

Zusammenfassung:	A method for recognising a communication protocol of data packets (M1, M2) travelling over a communication bus (20). The method comprises a CRC check procedure (PCRC1, PCRC2) for processing a data packet (M1, M2) travelling over said communication bus (20), said CRC check procedure comprising: - calculating a first checksum string (CKS1) by processing the payload portion (S1) of said data packet, according to a first CRC-generation engine associated to said first communication protocol (PR1); - calculating a second checksum string (CKS2) by processing the payload portion (S1) of said data packet, according to a second CRC-generation engine associated to said second communication protocol (PR2); - comparing with said first and second checksum strings (CKS1, CKS2) with the CRC portion (S2) of said data packet.
