English abstract:
This paper presents a model for the integration of subsystems with a varying degree of synchrony into a heterogenous system. While the synchronous part supports hard real-time requirements, the quasi-synchronous part is layered on a synchronous part and inherits properties like bounded drifts, bounded clock value deviation and improved failure detection. The synchronous part will be realized with a time-triggered communication system that supports also an event-triggered channel for the quasi-synchronous part.
The integration of event-triggered functions with relaxed timing properties makes sense if legacy systems or complex algorithms that cannot be temporally verified have to be used. Dependability is preserved by the failure detector subsystem that monitors the event-triggered part and extends the fault hypothesis to cover also performance failures.
The main benefit of the proposed architecture is the support of resource-efficient and economically feasible hard real-time dependable systems.
