Service Improvements in Real-Time Uniprocessor Scheduling With Single Errors
IEEE Access, 2021 Mixed-criticality scheduling in modern deeply embedded mission and safety-critical systems needs to consider delivered service, that is, the runtime in low criticality mode.

MultiPARTES: Multicore Virtualization for Mixed-Criticality Systems [PDF]
2013 Euromicro Conference on Digital System Design, 2013 Modern embedded applications typically integrate a multitude of functionalities with potentially different criticality levels into a single system. Without appropriate preconditions, the integration of mixed-criticality subsystems can lead to a significant and potentially unacceptable increase of engineering and certification costs.

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.

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 ...

A Lazy Bailout Approach for Dual-Criticality Systems on Uniprocessor Platforms
Designs, 2019 A challenge in the design of cyber-physical systems is to integrate the scheduling of tasks of different criticality, while still providing service guarantees for the higher critical tasks in the case of resource-shortages caused by faults.

Extending resources for avoiding overloads of mixed-criticality tasks in cyber-physical systems
IET Cyber-Physical Systems, 2019 With the increasing number of services and industries including nuclear, chemical, aerospace, and automotive sectors in cyber-physical systems (CPSs), systems are being severely overloaded.

Implementing Mixed-criticality Systems Upon a Preemptive Varying-speed Processor [PDF]
Leibniz Transactions on Embedded Systems, 2014 A mixed criticality (MC) workload consists of components of varying degrees of importance (or "criticalities"); the more critical components typically need to have their correctness validated to greater levels of assurance than the less critical ones ...

FlexPRET: A processor platform for mixed-criticality systems [PDF]
2014 IEEE 19th Real-Time and Embedded Technology and Applications Symposium (RTAS), 2014 Mixed-criticality systems, in which multiple tasks of varying criticality execute on a single hardware platform, are an emerging research area in real-time embedded systems. High-criticality tasks require spatial and temporal isolation guarantees for independent verification, and the task set should efficiently utilize hardware resources.

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 ...

Learning-Oriented QoS- and Drop-Aware Task Scheduling for Mixed-Criticality Systems
Computers, 2022 In Mixed-Criticality (MC) systems, multiple functions with different levels of criticality are integrated into a common platform in order to meet the intended space, cost, and timing requirements in all criticality levels.
