Context-Aware Graceful Degradation for Mixed-Criticality Scheduling in Autonomous Systems

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems
Autonomous systems are of high complexity and often regarded as mixed-criticality systems (MCSs) in which functions are allocated criticality levels according to risk assessment based on safety standards.

Uniprocessor Mixed-Criticality Scheduling with Graceful Degradation by Completion Rate

IEEE Real-Time Systems Symposium, 2018
The scheduling of mixed-criticality (MC) systems with graceful degradation is considered, where LO-criticality tasks are guaranteed some service in HI mode in the form of minimum cumulative completion rates.

Scheduling optimization with partitioning for mixed-criticality systems

Journal of Systems Architecture, 2019
Abstract 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.

Incorporating Robustness and Resilience into Mixed-Criticality Scheduling Theory

IEEE International Symposium on Real-Time Distributed Computing, 2019
Mixed-criticality scheduling theory (MCSh) was developed to allow for more resource-efficient implementation of systems comprising different components that need to have their correctness validated at different levels of assurance. As originally defined,

EDF-Based Mixed-Criticality Scheduling with Graceful Degradation by Bounded Lateness

IEEE International Conference on Embedded and Real-Time Computing Systems and Applications, 2019
Mixed-criticality (MC) scheduling has been proposed for embedded real-time systems to alleviate the dilemma between runtime resource utilization and worst-case temporal guarantees for critical functions. The approach of dropping all low-criticality tasks

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.

Introducing Utilization Caps into Mixed-Criticality Scheduling

2016 Euromicro Conference on Digital System Design (DSD), 2016
We 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.

JMC: Jitter-Based Mixed-Criticality Scheduling for Distributed Real-Time Systems

IEEE Internet of Things Journal, 2019
These days, the term of Internet of Things (IoT) becomes popular to interact and cooperate with individual smart objects, and one of the most critical challenges for IoT is to achieve efficient resource sharing as well as ensure safety-stringent timing ...

Memory-Aware Scheduling for Mixed-Criticality Systems

2016
In this paper, by taking both memory-access and computation time cost into consideration, a two-phase execution, i.e. memory-access phase first to fetch the instructions and required data, and then computation, is proposed to model mixed criticality tasks.

Partitioned Scheduling With Shared Resources on Imprecise Mixed-Criticality Multiprocessor Systems

IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems
Both resource access protocols and real-time scheduling algorithms have been extensively studied in classic embedded real-time systems. However, there has been relatively little attention given to the resource access protocol and real-time scheduling ...
