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 ...

System-Level Scheduling of Mixed-Criticality Traffics in Avionics Networks [PDF]
IEEE Access, 2016 System-level mixed-criticality design aims at reducing production cost and enhancing resource efficiency. This paper studies the technology of integrating mixed-criticality avionics traffics for Avionics Full-Duplex Switched Ethernet (AFDX) network ...

A semi-partitioned model for mixed criticality systems [PDF]
Journal of Systems and Software, 2019 Many Mixed Criticality algorithms have been developed with an assumption that lower criticality-level tasks may be abandoned in order to guarantee the schedulability of higher-criticality tasks when the criticality level of the system changes. But it is valuable to explore means by which all of the tasks remain schedulable through these criticality ...

Research on semi-partitioned scheduling algorithm in mixed-criticality system
Cognitive Robotics, 2021 In order to overcome the problem that in a mixed-critical system, once the critical level of the system changes, lower-critical tasks may be abandoned in order to ensure the schedulability of higher-critical tasks. A semi-partitioned scheduling algorithm

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.

Partition and Scheduling of the Mixed-Criticality Tasks Based on Probability
IEEE Access, 2019 In the mixed-criticality (MC) system, it is important to achieve better execution quality for the tasks with low criticality (LO tasks) while guaranteeing the completion of tasks with high criticality (HI tasks).

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.

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.
