The increased complexity of automotive and industrial networks and the need for data transparency and information exchange within the overall system led to the introduction of gateways. Theoretically, the term gateway is not quite correctly used in automotive applications. In the literature, the term gateway' is used for a network node of a communication network equipped for interfacing with another network that uses different protocols. It may contain devices such as protocol translation, rate converters and signal translators to provide system interoperability. In general, the gateway functionality could be implemented in software, as long as several CAN modules are available in the ECU. But a large amount of messages would cause a high load on the CPU, leaving less performance for the ECU control applications until real-time operation can no longer be guaranteed. This paper has shown and compared the structure as well as the advantages and disadvantages of both implementations. Also it was shown that it is possible to adapt protocol interface cells to use it in a modular gateway. This modular gateway combines the advantages of discrete and complex gateway implementations. It is flexible in system structure and reduces the load of the host CPU or the Gateway Control Unit significantly. First implementations and evaluation results of an exemplary gateway were demonstrated.
