Abstract
An electronic module in a J1939-compatible network requires to be equipped with a CAN protocol controller, which might be integrated on the main CPU or is attached to the CPU as a separate chip. Besides the fundamental functions required to transmit and receive CAN-compatible messages, the CAN hardware can support the CPU effectively, if the typical communication structure of J1939 was respected during the design of the CAN controller. It is shown that the CPU's management of, especially, received messages can be accelerated, if the CAN controller's architecture reflects the internal structure of the J1939 recommendations.
