Sustainability in Mixed-Criticality Scheduling
2017 IEEE Real-Time Systems Symposium (RTSS), 2017 Sustainability is a formalization of the requirement for scheduling algorithms and schedulability tests that a system deemed to be correctly schedulable should remain so if its run-time behavior is better than anticipated. The notion of sustainability is extended to mixed-criticality systems, and sustainability properties are determined for a variety ...

Generalized mixed-criticality scheduling based on RUN
Proceedings of the 23rd International Conference on Real Time and Networks Systems, 2015 Recent works on mixed--criticality (MC) scheduling algorithms have produced impressive results in terms of schedulability performances but at the expense of a large number of preemptions. Besides, not all MC scheduling algorithms can handle more than two criticality levels.

Time-Triggered Scheduling of Mixed-Criticality Systems
ACM Transactions on Design Automation of Electronic Systems, 2017 Real-time and embedded systems are moving from the traditional design paradigm to integration of multiple functionalities onto a single computing platform. Some of the functionalities are safety critical and subject to certification. The rest of the functionalities are nonsafety critical and do not need to be certified. Designing efficient

Scheduling Mixed-Criticality Real-Time Systems
, 2013 This dissertation addresses the following question to the design of scheduling policies and resource allocation mechanisms in contemporary embedded systems that are implemented on integrated computing platforms: in a multitasking system where it is hard to estimate a task's worst-case execution time, how do we assign task priorities so that 1) the ...

Scheduling of mixed-criticality systems with RUN
2015 IEEE 20th Conference on Emerging Technologies & Factory Automation (ETFA), 2015Mixed-criticality systems emerged with the aim of reconciling safety requirements and efficient use of multi-processor or uniprocessor platforms. On multi-processors, recent works on mixed-criticality have produced impressive results in terms of speed-up factor. But these solutions, based on Pfair-like scheduling algorithms, entail too many preemptions

Mixed-criticality scheduling with memory bandwidth regulation
2018 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2018Mixed-criticality (MC) multicore system design must reconcile safety guarantees and high performance. The interference among cores on shared resources in such systems leads to unpredictable temporal behaviour. Memory bandwidth regulation among different cores can be a useful tool to mitigate the interference when accessing main memory.

On the Scheduling of Fault-Tolerant Mixed-Criticality Systems
Proceedings of the 51st Annual Design Automation Conference, 2014We consider in this paper fault-tolerant mixed-criticality scheduling, where heterogeneous safety guarantees must be provided to functionalities (tasks) of varying criticalities (importances). We model explicitly the safety requirements for tasks of different criticalities according to safety standards, assuming hardware transient faults.

Scheduling optimization with partitioning for mixed-criticality systems
Journal of Systems Architecture, 2019Abstract Modern real-time embedded and cyber-physical systems comprise a large number of applications, often of different criticalities, executing on the same computing platform. Partitioned scheduling is used to provide temporal isolation among tasks with different criticalities.

Introducing Utilization Caps into Mixed-Criticality Scheduling
2016 Euromicro Conference on Digital System Design (DSD), 2016We are concerned with mixed-criticality systems where a set of low-criticality (LO) and high-criticality (HI) tasks share one processor and are scheduled under EDF-VD algorithm. EDF-VD implements two operation modes: LO and HI. In LO mode, one or more HI tasks may exceed their execution budgets, which then causes a change to HI mode in the system.
