Towards An Evaluation Infrastructure For Automotive Multicore Real-Time Operating Systems

The automotive industry is on the road to multicore and already included supporting features in their AUTOSAR. standard, yet they could not decide for a multicore resource locking protocol. It is crucial for the future acceptance and possibilities of multicore systems to allow for informed decisions on this topic, as it immediately impacts the inter-core communication performance and thereby the value-cost ratio of such systems. We present the design of a real-time operating system simulator that allows to evaluate the different multicore synchronisation mechanisms of the real-time research community regarding their fitness for automotive hard real-time applications. You can reuse the key design idea of this simulator for any simulation based tool for the early timing evaluation of different real-time mechanisms, e. g. scheduling algorithms.
