Abstract
A communication module for connecting a serial bus, which transmits data in packets, to a plurality of system buses of a gateway, which transmit data word by word, the communication module having a communication protocol unit, which is connected to the serial bus, for converting between data packages and messages, which are respectively made up of a plurality of data words, a message relaying unit for relaying messages between at least one message memory and the communication protocol unit, as well as buffer memories, a plurality of interface units, which are respectively connected to an associated system bus of the gateway, each interface unit being connected to at least one associated buffer memory, which stores a message temporarily, a transmission of data words via a plurality of system buses and their associated interface units from and to the buffer memories of the interface units taking place simultaneously, without delay.
