FPGA Implementation of CAN (Controller Area Network) Protocol

Abstract

The CAN (Controller Area Network) communication serial protocol is a carrier­ sense multiple access protocol with collision detection and arbitration on message priority (CSMA/CD+AMP) with a multi-master serial communication bus using twisted pair cables as transmission medium. It suites applications require high number of short messages for multi recipients. System-wide data consistency is mandatory in a short period of time with high reliability in rugged operating environments. The CAN protocol is well adapted for real-time controls applications due to its predictable medium access approach with the collision avoidance, hierarchically identifier message and multiple errors detection features.
