Flexible and Dynamic Scheduling of Mixed-Criticality Systems
Sensors, 2022 A mixed-criticality system refers to an integrated embedded system in which tasks with different criticality levels run on a shared computing platform. In the design and development of mixed-criticality systems, how to schedule tasks to ensure that high ...

Allocation algorithms for multicore partitioned mixed-criticality real-time systems [PDF]
PeerJ Computer ScienceMulticore systems introduced a performance increase over previous monocore systems. As these systems are increasingly finding application in critical domains, it arises a necessity to develop novel methodologies for their efficient resource allocation ...

Task Migration and Scheduler for Mixed-Criticality Systems [PDF]
Sensors, 2022 The interference between software components is increasing in safety-critical domains, such as autonomous driving. Low-criticality (LC) tasks, such as vehicle communication, may control high-criticality (HC) tasks, such as acceleration.

Energy efficient partition allocation in mixed-criticality systems.
PLoS ONE, 2019 This paper addresses the problem of energy management of mixed criticality applications in a multi-core partitioned architecture. Instead of focusing on new scheduling algorithms to adjust frequency in order to save energy, we propose a partition to CPU ...

Toward Resilience in Mixed Critical Industrial Control Systems: A Multi-Disciplinary View
IEEE Access, 2022 Future industrial control systems face the need for being highly adaptive, productive, and efficient, yet providing a high level of safety towards operating staff, environment, and machinery.

Robust Mixed-Criticality Systems [PDF]
IEEE Transactions on Computers, 2018 Certification authorities require correctness and survivability. In the temporal domain this requires a convincing argument that all deadlines will be met under error free conditions, and that when certain defined errors occur the behaviour of the system is still predictable and safe.

Experience Report: Towards Extending an OSEK-Compliant RTOS with Mixed Criticality Support [PDF]
e-Informatica Software Engineering Journal, 2018 Background: With an increase of the number of features in a vehicle, the computational requirements also increase, and vehicles may contain up to 100 Electronic Control Units (ECUs) to accommodate these requirements.

Schedulability of probabilistic mixed-criticality systems [PDF]
Real-Time Systems, 2021 AbstractMixed-criticality systems often need to fulfill safety standards that dictate different requirements for each criticality level, for example given in the ‘probability of failure per hour’ format. A recent trend suggests designing this kind of systems by jointly scheduling tasks of different criticality levels on a shared platform.

Mixed-Criticality Scheduling of Sporadic Task Systems [PDF]
, 2011 We consider the scheduling of mixed-criticality task systems, that is, systems where each task to be scheduled has multiple levels of worst-case execution time estimates. We design a scheduling algorithm, EDF-VD, whose effectiveness we analyze using the processor speedup metric: we show that any 2-level task system that is schedulable on a unit-speed ...
