As an enhancement of the established CAN 2.OB standard, the Fraunhofer IPMS core supports both the ISO CAN FD as well as the non-ISO CAN FD. In addition to this enhancement, which also allows for the connectivity of complex electronic control units with greater data throughput, the Fraunhofer IPMS CAN FD IP Core provides other useful functions which support the host processor in the management of the IP Core communication. The transmit buffer of the IP Core can be operated in first-in-first-out or priority mode. Here, messages of higher priority are automatically sent out first. In addition, the core supports time-triggered CAN (TTCAN) according to ISO 11898-4. With that, it is possible to set timeframes for sending messages at defined time points and mark received messages with a time-stamp. Communications network designers can then therefore ensure that data from individual control units is available in real time. Although primarily used in the automotive industry, CAN 2.OB and CAN FD protocols are by no means limited to this sector.
