Predictability in Mixed-Criticality Systems

2018 IEEE 24th International Conference on Embedded and Real-Time Computing Systems and Applications (RTCSA), 2018
In 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.

Mixed-criticality processing pipelines

Design, Automation & Test in Europe Conference & Exhibition (DATE), 2017, 2017
While a number of schemes exist for mixed-criticality scheduling in a single processor setting, no solution exists to cover the industry need for end-to-end scheduling across multiple processors in a pipeline. In this paper, we present an end-to-end zero-slack rate-monotonic scheme (ZSRM) based on real-time pipelines, called the ZSRM pipeline scheduler,

Sustainability in Mixed-Criticality Scheduling

2017 IEEE Real-Time Systems Symposium (RTSS), 2017
Sustainability is a formalization of the requirement for scheduling algorithms and schedulability tests that a system deemed to be correctly schedulable should remain so if its run-time behavior is better than anticipated. The notion of sustainability is extended to mixed-criticality systems, and sustainability properties are determined for a variety ...

Criticality in a dynamic mixed system

Physical Review E, 2001
We 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

Mixed-Criticality Systems as a Service for Non-critical Tasks

2016 IEEE 19th International Symposium on Real-Time Distributed Computing (ISORC), 2016
Mixed-Criticality Systems are capable of accommodatingtasks of varying criticality. In this paper, these are [life, mission, and non-critical]. Tasks usually have an overestimatedexecution time to allow for the Worst Case Execution Time(WCET). When these tasks finish execution prior to their allottedexecution time due to pessimistic assumptions present

Criticality-Aware Partitioning for Multicore Mixed-Criticality Systems

2016 45th International Conference on Parallel Processing (ICPP), 2016
The 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 ...

Mixed critical system design and analysis

Proceedings of the tenth ACM international conference on Embedded software, 2012
With 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.

IDAMC: A NoC for mixed criticality systems

2013 IEEE 19th International Conference on Embedded and Real-Time Computing Systems and Applications, 2013
Increasing demand for performance and further integration promotes the use of multi- and many-core systems - also in safety-critical embedded systems. In this domain, hardware platforms obviously have to support real-time, predictability constrained applications such as an anti-lock braking system.

Embedded systems for safety-critical and mixed-criticality applications

2013 2nd Mediterranean Conference on Embedded Computing (MECO), 2013
Summary form only given. Multi-core processors promise a number of benefits for development of dependable embedded systems. They offer higher performance than single-core processors and consume less energy than high-speed single cores of equivalent computational power, reducing this way a number of computational nodes and wiring in a system and ...
