Accurate Strategy for Mixed Criticality Scheduling [PDF]
International Workshop on Verification and Evaluation of Computer and Communication Systems, 2020 In mixed criticality systems, functionalities with different criticalities share the same execution platform. The goal of a mixed criticality scheduling algorithm is to ensure a safe execution of the highest criticality tasks while using efficiently the execution platform.

Partition and Scheduling of the Mixed-Criticality Tasks Based on Probability
IEEE Access, 2019 In the mixed-criticality (MC) system, it is important to achieve better execution quality for the tasks with low criticality (LO tasks) while guaranteeing the completion of tasks with high criticality (HI tasks).

Intractability Issues in Mixed-Criticality Scheduling
Euromicro Conference on Real-Time Systems, 2018 In seeking to develop mixed-criticality scheduling algorithms, one encounters challenges arising from two sources. First, mixed-criticality scheduling is an inherently an on-line problem in that scheduling decisions must be made without access to all the information that is needed to make such decisions optimally - such information is only revealed ...

Mixed-Criticality Scheduling with Dynamic Memory Bandwidth Regulation [PDF]
2018 IEEE 24th International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA), 2018 Mixed-criticality multicore system design must often guarantee both safety and high performance. Memory bandwidth regulation among different cores can be a useful tool for guaranteeing safety, as it mitigates the interference when accessing main memory ...

Mixed-Criticality Scheduling with Dynamic Redistribution of Shared Cache
CoRR, 2017 The design of mixed-criticality systems often involvespainful tradeoffs between safety guarantees and performance.However, the use of more detailed architectural modelsin the design and analysis of scheduling arrangements for mixedcriticalitysystems can ...

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.

A Hardware-Aware Application Execution Model in Mixed-Criticality Internet of Things
Mathematics, 2022 The Real-Time Internet of Things is an emerging technology intended to enable real-time information communication and processing over a global network of devices at the edge level. Given the lessons learned from general real-time systems, where the mixed-

Energy-Aware Adaptive Mixed-Criticality Scheduling with Semi-Clairvoyance and Graceful Degradation
ACM Transactions on Embedded Computing Systems, 2023 The classic Mixed-Criticality System (MCS) task model is a non-clairvoyance model in which the change of the system behavior is based on the completion of high-criticality tasks while dropping low-criticality tasks in high-criticality mode. In this paper,

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,

Analysis-Runtime Co-design for Adaptive Mixed Criticality Scheduling
IEEE Real Time Technology and Applications Symposium, 2022 In this paper, we use the term “Analysis-Runtime Co-design” to describe the technique of modifying the runtime protocol of a scheduling scheme to closely match the analysis derived for it. Carefully designed modifications to the runtime protocol make the
