Semi-partitioned Mixed-Criticality Scheduling [PDF]

open access: yes, 2017
Scheduling isolation in mixed-criticality systems is challenging without sacrificing performance. In response, we propose a scheduling approach that combines server-based semi-partitioning and deadline-scaling. Semi-partitioning (whereby only some tasks migrate, in a carefully managed manner), hitherto used in single criticality systems, offers good ...

Dynamic Constraints for Mixed-Criticality Systems [PDF]

open access: yesProceedings 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.

Engineering mixed-criticality interactive applications [PDF]

open access: yesProceedings of the 8th ACM SIGCHI Symposium on Engineering Interactive Computing Systems, 2016
In the field of critical systems, safety standards such as DO-178C define Development Assurance Levels (DALs) for software systems (or sub-systems). The higher the consequence of a failure the higher DAL is required by certification authorities. Developing a system at a DAL A requires the use of formal description techniques and is thus expensive.

Compensating Adaptive Mixed Criticality Scheduling [PDF]

open access: yesProceedings of the 30th International Conference on Real-Time Networks and Systems, 2022
The majority of prior academic research into mixed criticality systems assumes that if high-criticality tasks continue to execute beyond the execution time limits at which they would normally finish, then further workload due to low-criticality tasks may

Towards Fully Jitterless Applications: Periodic Scheduling in Multiprocessor MCSs Using a Table-Driven Approach

open access: yesApplied Sciences, 2020
In mixed criticality systems (MCSs), the time-triggered scheduling approach focuses on a special case of safety-critical embedded applications which run in a time-triggered environment.

Experience Report: Towards Extending an OSEK-Compliant RTOS with Mixed Criticality Support [PDF]

open access: yese-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.

ATMP-CA: Optimising Mixed-Criticality Systems Considering Criticality Arithmetic [PDF]

open access: yes, 2021
Many safety-critical systems use criticality arithmetic, an informal practice of implementing a higher-criticality function by combining several lower-criticality redundant components or tasks.

Reducing Dynamic Power Consumption in Mixed-Critical Real-Time Systems

open access: yesApplied Sciences, 2020
In this paper, we study energy minimization consumption of a mixed criticality real-time system on uni-core. Our focus is on a new scheduling scheme to decrease the frequency level in order to conserve power.

Mixed Critical Earliest Deadline First [PDF]

open access: yes2013 25th Euromicro Conference on Real-Time Systems, 2013
Using the advances of the modern microelectronics technology, the safety-critical systems, such as avionics, can reduce their costs by integrating multiple tasks on one device. This makes such systems essentially mixed-critical, as this brings together different tasks whose safety assurance requirements may differ significantly. In the context of mixed-
