Mixed-Criticality Scheduling on Multiprocessors with Service Guarantees

2018 IEEE 21st International Symposium on Real-Time Distributed Computing (ISORC), 2018
Mixed-criticality (MC) systems are composed of tasks with varying criticality co-hosted on a single shared platform. In conventional MC systems, upon criticality change, the lower criticality tasks are penalized to guarantee resources for the higher criticality ones.

Schedulability Analysis of Mixed-Criticality Systems on Multiprocessors

2012 24th Euromicro Conference on Real-Time Systems, 2012
The advent of multicore processors has attracted many safety-critical systems, e.g., automotive and avionics, to consider integrating multiple functionalities on a single, powerful computing platform. Such integration leads to host functionalities with different criticality levels on the same platform.

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.

Relaxing Mixed-Criticality Scheduling Strictness for Task Sets Scheduled with FP

2012 24th Euromicro Conference on Real-Time Systems, 2012
Current trends in the embedded systems field tend to collocate multiple functionalities upon a single computing platform, the aim being to reduce both the size and cost of embedded systems. Nevertheless, it is unlikely that all functionalities share the same level of criticality, and certification of the system has to be achieved using varying degrees ...

A probabilistic scheduling framework for mixed-criticality systems

Proceedings of the 53rd Annual Design Automation Conference, 2016
We propose a probabilistic scheduling framework for the design and development of mixed-criticality systems, i.e., where tasks with different levels of criticality need to be scheduled on a shared resource. Whereas highly critical tasks normally require hard real-time guarantees, less or non-critical ones may be degraded or even temporarily discarded ...

Battery-Aware Scheduling of Mixed Criticality Systems

2014
Wireless systems such as satellites and sensor networks are often battery-powered. To operate optimally they must therefore take the performance properties of real batteries into account. Additionally, these systems, and therefore their batteries, are often exposed to loads with uncertain timings. Mixed criticality and soft real-time systems may accept

Mixed-criticality Scheduling: Improved Resource-augmentation Results.

, 2010
Many safety-critical embedded systems are sub-ject to certification requirements; some systems may be required to meet multiple sets of certification re-quirements, from different certification authorities.

Specifying Fault-Tolerant Mixed-Criticality Scheduling

© The Author(s), under exclusive license to Springer Nature Switzerland AG 2024. This paper extends the ideas behind rely-guarantee conditions to cope with the specification of real-time schedulers that support Fixed Priority (FP) scheduling. The sporadic task model is considered in which tasks with defined minimum periods and worst-case execution ...
