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 ...

Mixed Criticality in Control Systems
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 2014 Abstract The complexity of industrial embedded systems is increasing continuously. Companies try to keep a leading position by offering additional functionalities and services. Systems are to be composed by multiple sensor, actuation and computation subsystems running in a coordinated way on a distributed platform.

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.

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.

Dynamic Constraints for Mixed-Criticality Systems [PDF]
Proceedings of the International Conference on Omni-Layer Intelligent Systems, 2019 We define quality of service requirements for mixed-criticality systems based on min-plus algebra rather than discrete criticality levels. The requirements (1) unify a spectrum of weakly-hard real-time requirements with strongly-hard real-time and soft real-time as extreme cases and (2) support dynamic tuning of task importance.

A Survey of Research into Mixed Criticality Systems [PDF]
ACM Computing Surveys, 2017 This survey covers research into mixed criticality systems that has been published since Vestal’s seminal paper in 2007, up until the end of 2016. The survey is organised along the lines of the major research areas within this topic. These include single processor analysis (including fixed priority and Earliest Deadline First (EDF) scheduling, shared ...

Bounding the Demand of Mixed-Criticality Industrial Wireless Sensor Networks
IEEE Access, 2017 Wireless sensor networks (WSNs) have been widely used in industrial systems. Industrial systems demand a high degree of reliability and real-time requirements in communications.

Overhead Based Cluster Scheduling of Mixed Criticality Systems on Multicore Platform
IEEE Access, 2023 The cluster-based technique is gaining focus for scheduling tasks of mixed-criticality (MC) real-time multicore systems. In this technique, the cores of the MC system are distributed in groups known as clusters. When all cores are distributed in clusters,

Service adaptions for mixed-criticality systems [PDF]
2014 19th Asia and South Pacific Design Automation Conference (ASP-DAC), 2014 Complex embedded systems are typically mixed-critical, where heterogeneous guarantees must be provided for functionalities of different criticalities. We study in this paper the reconfiguration of services provided to low criticality tasks in reaction to the overruns of high criticality tasks.

ILP Approach for Periodic Dependent Tasks in Multicore Mixed-criticality systems [PDF]
Mathematics and Computational Sciences, 2022 Today, the desire to use mixed-critical systems in the industry is increasing. In order to provide the processing power required by mixed-critical systems, multi-core architectures are considered a suitable option.
