Multi-processor systems have been in wide use for about ten years. During this time, several programming models have appeared in different domains. In particular, the academic community has been active in devising methods, often model-driven, to program heterogeneous embedded multi-processor platforms. This session analyzes the current standing from different perspectives, namely, from researchers working in methods in academia, from companies offering solutions and from companies requiring solutions.

Abstract
As the amount of software in the car continues growing, automotive companies have shifted to multicore microcontroller architectures as a way to contain both the number of ECUs (cost) and their power consumption (mileage). New multicore microcontrollers can deliver more performance and hence allow mapping more functions on it. At the same time, this extra performance is delivered at clock frequencies comparable to previous generations, hence keeping the more and more important power consumption under control. New challenges both from functional and performance angles are introduced when porting an existing software stack to a new multicore microcontroller architecture. From the functional aspect, new bugs such as race conditions, data coherence, etc are introduced. From the performance angle, different functions running on different cores do still share all other hardware resources, such as memories, on-chip busses and peripherals, which may introduce significant jitter on the software execution. Finding the appropriate configuration of such hardware resources that provides sufficient performance in all conditions is a daunting task. This is all very important especially for safety critical applications where "freedom of interference" must be ensured to achieve certification. In this presentation we will discuss, how multicore microcontroller simulation models (a.k.a. virtual prototypes) are used nowadays throughout the Automotive Supply chain, from Semiconductor companies, to Tier1 and to OEMs, to deal with the challenges of debugging and analyzing software on multicore architectures.
