Embedded systems for safety-critical and mixed-criticality applications
2013 2nd Mediterranean Conference on Embedded Computing (MECO), 2013Summary 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 ...

A Wormhole NoC Protocol for Mixed Criticality Systems
2014 IEEE Real-Time Systems Symposium, 2014Lack of scalability and difficulties in predicting the temporal behaviour of bus-based architectures has lead to the development of Network-on-Chip (NoC) protocols that provide a schedulable resource for moving data across multi-core platforms. Wormhole switching and credit-based flow control protocols have been used to support flit-level priority ...

A System-on-a-Chip Platform for Mixed-Criticality Applications
2010 13th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing, 2010High–integrity systems are deployed in order to realize safety–critical applications. To meet the rigorous requirements in this domain, these systems require a sophisticated approach to design, verfication, and certification. Not only safety consideration shave an impact on a product’s overall dependability, but also security has to be taken into ...

A Practical Degradation Model for Mixed-Criticality Systems
2019 IEEE 22nd International Symposium on Real-Time Distributed Computing (ISORC), 2019Existing Mixed Criticality System (MCS) task models consider criticality as the relative importance of a task and use it to achieve graceful degradation of the system either by suspending or degrading tasks with relatively lower criticality level than the overloading task. Graceful degradation based on this notion of criticality as a relative parameter

A Review of Recent Techniques in Mixed-Criticality Systems
Journal of Circuits, Systems and Computers, 2019Unlike traditional embedded systems that almost have only one criticality level, many complex embedded systems nowadays are mixed-critical and are more and more widely used. There has been a lot of research on mixed-criticality (MC) systems. In this paper, we present a survey on the MC systems on these research.

Memory-Aware Scheduling for Mixed-Criticality Systems
2016In 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.

Adaptive Workload Management in Mixed-Criticality Systems
ACM Transactions on Embedded Computing Systems, 2016Due to the efficient resource usage of integrating tasks with different criticality onto a shared platform, the integration with mixed-criticality tasks is becoming an increasingly important trend in the design of real-time systems. One challenge in such a mixed-criticality system is to maximize the service for low-critical tasks, while ...

A probabilistic scheduling framework for mixed-criticality systems
Proceedings of the 53rd Annual Design Automation Conference, 2016We 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 ...
