Abstract: A user interface between a FlexRay communications module, which is connected to a FlexRay communications connection via which messages are transmitted, and which includes a message memory for the temporary storage of messages from the FlexRay communications connection or for the FlexRay communications connection, and a FlexRay user assigned to the FlexRay communications module. In order to make possible a particularly resource-saving and resource-conserving connection of the user to the FlexRay communications module, it is provided that the user interface has a device for the temporary storage of the messages. The device includes at least one message memory which has a first connection to FlexRay the communications module and a second connection to the user. Message memory may be implemented as a dual-ported RAM.

Abstract: A circuit arrangement, having a circuit and a computer unit is provided, in which the circuit and the computer unit are connected to one another via multiple lines for transmitting a number of signals which are embodied as information signals. The circuit has a multiplexer for combining signals, the multiplexer being connected to the computer unit via an additional line.
