Temporal independence validation of an IEC-61508 compliant mixed-criticality system based on multicore partitioning

The transition from conventional federated embedded system architectures to mixed-criticality integrated multicore architectures provides benefits in terms of cost, size, weight, scalability and reliability. As a consequence, integrated mixedcriticality solutions are an objective for many embedded systems developers, although the challenges related with the safety certification of multicore approaches may hinder their adoption. Among many other stringent requirements, the safety standards demand to prove that the mixed-criticality systems are free of interferences, thus ensuring the spatial and temporal interdependence among applications. This paper contributes with a measured based temporal independence validation of a partitioned multicore mixed-criticality system.
