Mixed Criticality Systems—A History of Misconceptions?
IEEE Design & Test, 2016Mixed criticality systems have recently received much attention both in research and in industrial design practice. However, industrial practice and much of the research community seem to follow different objectives and research directions. We will review the status of mixed criticality systems design and compare the open challenges with the current ...

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

Predictability in Mixed-Criticality Systems
2018 IEEE 24th International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA), 2018In this paper, we revisit and refine our previous research on schedulability testing for fixed set of dual-critical jobs. Such systems can be tested for tight job termination time bounds using simulation, under the prerequisite that the scheduling policy be predictable.

Virtualizing Mixed-Criticality Operating Systems
2016 VI Brazilian Symposium on Computing Systems Engineering (SBESC), 2016The forever growing number of embedded control units in some applications such as cars or airplanes are increasing system complexity and making harder to coordinate all this hardware. The increasing capacity of embedded hardware and the advances in virtualization technology make it possible to deal with this problem.

Service guarantee exploration for mixed-criticality systems
2014 IEEE 20th International Conference on Embedded and Real-Time Computing Systems and Applications, 2014Most mixed-criticality scheduling algorithms have the problem of service interruption for low-critical tasks, which has prompted several recent studies on providing various service guarantees for such tasks. In this paper, focusing on dual-criticality systems, we explore the best achievable service guarantees for low-critical tasks in different running

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 ...

Reliability-Driven System-Level Synthesis for Mixed-Critical Embedded Systems
IEEE Transactions on Computers, 2013This paper proposes a design methodology that enhances the classical system-level design flow for embedded systems to introduce reliability-awareness. The mapping and scheduling step is extended to support the application of hardening techniques to fulfill the required fault management properties that the final system must exhibit; moreover, the ...

Mixed critical system design and analysis
Proceedings of the tenth ACM international conference on Embedded software, 2012With increasing use of embedded systems in safety critical systems, architectures and design processes for safety have become a primary objective in systems design. Most such systems are also time critical leading to safety and time critical systems.

Mixed-criticality networks for adaptive systems
29th Digital Avionics Systems Conference, 2010A crucial aspect of mission-critical vehicles is their reaction to environmental or system-internal changes. Ideally, the new situation is autonomously assessed and the vehicle's behavior is adapted accordingly. Modern mission-critical vehicles realize a network-centric design approach, for one reason because it follows the inherent requirements of ...

Temporal partitioning for mixed-criticality systems
ETFA2011, 2011In embedded systems, such as aerospace crafts and automobiles, it is desirable to run several real-time applications of different criticality on a single computing board by exploiting temporal partitioning. The applications, however, are usually developed by different organizations independently.
