Implementation of CAN controller with FPGA structures

In this article is present a stand-alone controller for the controller area network (CAN) protocol. The design contains all necessary features required to implement a high performance communication protocol. The CAN controller with a simple bus line connection performs all the functions of the physical and data-link layers. The application layer is provided by a microcontroller, to which the CAN controller connects through general purpose non-multiplexed parallel 8-bits bus.
