A Survey of Research into Mixed Criticality Systems
This survey covers research into mixed criticality systems that has been published since Vestal’s seminal paper in 2007, up until the end of 2016. The survey is organised along the lines of the major research areas within this topic. These include single processor analysis (including fixed priority and EDF scheduling, shared resources and static and synchronous scheduling), multiprocessor analysis, realistic models, and systems issues. The survey also explores the relationship between research into mixed criticality systems and other topics such as hard and soft time constraints, fault tolerant scheduling, hierarchical scheduling, cyber physical systems, probabilistic real-time systems, and industrial safety standards
Modeling Mixed-critical Systems in Real-time BIP
International audienceThe proliferation of multi- and manycores creates an important design problem: the design and verification for mixed-criticality constraints in timing and safety, taking into account the resource sharing and hardware faults. In our work, we aim to contribute towards the solution of these problems by using a formal design language - the real time BIP, to model both hardware and software, functionality and scheduling. In this paper we present the initial experiments of modeling mixed-criticality systems in BIP
