Abstract

Computing units that are connected to one another via a bus system are synchronized in that two master units each cyclically output a time signal onto a data line of the bus system. The time signals are received by the computing unit to be synchronized. The unit checks the time signals with reference to its own time base. Particularly reliable synchronization of the computing units is ensured by this means.
