English abstract:
In mixed-criticality systems, applications with different
levels of criticality are integrated on the same computational
platform. Without a proper isolation of the different
applications of such a mixed-criticality system certification gets
expensive, because it has to be shown that application components
of lower criticality do not hamper the correct operation of the
critical applications. Therefore, all components - even the less
critical ones - have to be certified for the highest criticality
level. For single core platforms the use of hypervisors promises
to shield applications of different criticality from each other.
Timing problems may emerge when the hypervisor is ported
to a multicore platform where different cores access the global
memory concurrently. We show, that full temporal isolation of
applications executing on different cores is only achievable if the
hypervisor is run on appropriate hardware. The presented duallayer
bus arbiter enables critical applications to preserve isolation
properties and also improves the execution performance of noncritical
