Abstract

A gateway is provided for automatically routing messages between buses, the gateway being connected to multiple communication components for temporarily storing and transmitting messages via these buses, and having a gateway control unit which is connected to the communication components via a system bus for the exchange of messages, and which receives notification from each communication component of the occurrence therein of a message to be routed as an external event. The gateway control unit has a vector memory which includes a first memory region for storing communication component vectors, a communication component vector being provided for each message group of a communication component, and the vector indicating the point in time of the next expected internal event for a message that is temporarily stored in the communication component, and indicating a vector jump address to a message vector which is stored in a second memory region of the vector memory.
