Partitioned Scheduling With Shared Resources on Imprecise Mixed-Criticality Multiprocessor Systems
IEEE Transactions on Computer-Aided Design of Integrated Circuits and SystemsBoth 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 ...

Criticality-Aware EDF Scheduling for Constrained-Deadline Imprecise Mixed-Criticality Systems
IEEE Transactions on Computer-Aided Design of Integrated Circuits and SystemsEDF-VD first focuses on the classic mixed-criticality task model in which all low-criticality (LO) tasks are abandoned in the high-criticality mode, which is an effective dynamic priority scheduling algorithm for mixed-criticality systems.

Re-Thinking Mixed-Criticality Architecture for Automotive Industry
ICCD, 2020Mixed-Criticality System (MCS) has been considered widely within academic literature, but is proving difficulty to implement in industry as the theoretical models underpinning the research do not always consider industrial safety standards and practice ...

Criticality in a dynamic mixed system
Physical Review E, 2001We suggest a dynamic generalization of the simplest static hierarchical mixed model introduced by Shnirman and Blanter [Phys. Rev. Lett. 81, 5445 (1998); Phys. Rev. E. 60, 5111 (1998). We show that the stationary solution of the dynamic mixed model (DMM) demonstrates, in general, a linear form of the magnitude-frequency relation and may be considered a

Precise scheduling of mixed-criticality tasks by varying processor speed
International Conference on Real-Time and Network Systems, 2019In this paper, we extend the imprecise mixed-criticality (IMC) model to precise scheduling of tasks. We also integrate the IMC model with the dynamic voltage and frequency scaling (DVFS) technique to enable energy minimization.

Scheduling in time sensitive networks (TSN) for mixed-criticality industrial applications
IEEE International Workshop on Factory Communication Systems, 2018IEEE 802.1 Time-Sensitive Networking (TSN) is a set of IEEE standards that extend Ethernet for safety-critical and real-time applications. TSN is envisioned to be widely used in several applications areas, from industrial automation to in-vehicle ...

Criticality-Aware Partitioning for Multicore Mixed-Criticality Systems
2016 45th International Conference on Parallel Processing (ICPP), 2016The scheduling for mixed-criticality (MC) systems, where multiple activities have different certification requirements and thus different criticality on a shared hardware platform, has recently become an important research focus. In this work, considering that multicore processors have emerged as the de-facto platform for modern embedded systems, we ...

CARP: A Data Communication Mechanism for Multi-core Mixed-Criticality Systems
IEEE Real-Time Systems Symposium, 2019We present CARP, a predictable and high-performance data communication mechanism for multi-core mixed-criticality systems (MCS). CARP is realized as a hardware cache coherence protocol that enables communication between critical and non-critical tasks ...

Mixed-Criticality Multicore Scheduling of Real-Time Gang Task Systems
IEEE Real-Time Systems Symposium, 2019Mixed-criticality (MC) scheduling of sequential tasks (with no intra-task parallelism) has been well-explored by the real-time systems community. However, till date, there has been little progress on MC scheduling of parallel tasks.
