A scheduling framework for handling integrated modular avionic systems on multicore platforms
2017 IEEE 23rd International Conference on Embedded and Real-Time …, 2017•ieeexplore.ieee.org
Although multicore chips are quickly replacing uniprocessor ones, safety-critical embedded
systems are still developed using single processor architecture. The reasons mainly concern
predictability and certification issues. This paper proposes a scheduling framework for
handling Integrated Modular Avionics (IMA) on multicore platforms providing predictability as
well as flexibility in managing dynamic load conditions and unexpected temporal
misbehaviors of multicore. A new computational model is proposed to allow specifying a …

Although multicore chips are quickly replacing uniprocessor ones, safety-critical embedded systems are still developed using single processor architecture. The reasons mainly concern predictability and certification issues. This paper proposes a scheduling framework for handling Integrated Modular Avionics (IMA) on multicore platforms providing predictability as well as flexibility in managing dynamic load conditions and unexpected temporal misbehaviors of multicore. A new computational model is proposed to allow specifying a higher degree of flexibility and minimum performance requirements. Schedulability analysis is derived for providing off-line guarantees of real-time constraints in worst-case scenarios, and an efficient reclaiming mechanism is proposed to improve the average-case performance. Simulation and experimental results are reported to validate the proposed approach.
