Modeling and Assessment of Safety Critical Systems

With growing complexity of embedded controllers and applications, the design of safety critical systems becomes more and more challenging. Tools and frameworks help to manage such challenges but are often pricy and cover only certain aspects of the overall design or implementation workflow. In previous publications, we introduced a lightweight runtime environment and discussed concepts … Read more

Safety Architectures on Multicore Processors – Mastering the Time Domain

A key pattern for building safe architectures is a strict separation of QM and safety code, considering a separation not only in the memory domain but also in the time domain. On a multicore processor, this can be achieved by placing QM code on one core and safety code on another. This approach however brings … Read more

🇩🇪 Warp3 auf allen Kernen

Multicore Mikrocontroller bringen aufgrund ihrer Komplexität besondere Herausforderungen, wie die Inter-Core Kommunikation und den Schutz von Ressourcen vor unerlaubtem Zugriff mit sich. Zudem ist die Parametrisierung und Nutzung immer leistungsfähigerer und umfangreicherer Peripherie komplex und fordert den Anwender somit zusätzlich. Die Programmierung von Multicore Mikrocontrollern stellt Entwickler vor eine große Herausforderung. „Für die Umstellung auf … Read more

A monitoring based safety architecture for multicore microcontrollers

Separation in the data-, resource- and time-domain is a big challenge on multicore microcontrollers. Combined with dependencies in the same domains, the result very often is a fragile, complex structure that is difficult to handle. In a previous project, an innovative runtime environment, which is based on ideas of Adaptive AUTOSAR has been developed together … Read more
