On the Scheduling of Fault-Tolerant Mixed-Criticality Systems
Proceedings of the 51st Annual Design Automation Conference, 2014We consider in this paper fault-tolerant mixed-criticality scheduling, where heterogeneous safety guarantees must be provided to functionalities (tasks) of varying criticalities (importances). We model explicitly the safety requirements for tasks of different criticalities according to safety standards, assuming hardware transient faults.

Smart Certification of Mixed Criticality Systems
2005High integrity applications, such as those performing safety or security critical functions, are usually built to conform to standards such RTCA DO-178B [1] or UK Def Stan 00-55 [2]. Typically such standards define ascending levels of criticality each of which requires a different and increasingly onerous level of verification.

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 ...

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.

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 ...
