Temporal Isolation with Preemption Delay Accounting
Ref: CISTER-TR-140703 Publication Date: 16 to 19, Sep, 2014Abstract:
Reservation systems are generally employed to enforce
temporal isolation between applications. In the real-time
context the corresponding temporal isolation requires not only
the consideration of the direct interference due to execution of
higher priority tasks, but also the indirect cost of e.g. cacherelated
preemption delay. The accounting of this in a server-based
implementation of temporal isolation poses special challenges,
in particular when misbehaving in the form of overruns and
violation of the minimum inter-arrival time of an application
are to be covered. We present a novel approach to extend the
fault coverage and reduce the pessimism when compared to the
state of the art. Furthermore we demonstrate that the extra
implementation of the introduced mechanisms over the state of
the art can be very low on complexity.
