Providing higher performance than state-of-the-art embedded processors can deliver today will increase safety, comfort, number and quality of services, while also lowering emissions as well as fuel demands for automotive, avionic and automation applications. Engineers who design hard real-time embedded systems in such embedded domains express a need for several times the performance available today while keeping safety as major criterion. A breakthrough in performance is expected by parallelising hard real-time applications and running them on an embedded multi-core processor, which enables combining the requirements for high-performance with time-predictable execution.

The talk will present research approaches and results of the parallelisation and WCET (Worst-case Execution Time) analysis of industrial hard real-time applications. It shows how a WCET analysis of the communication and synchronization patterns can be performed and how a WCET speedup can be reached for parallelised programs based on parallel design patterns. Research approaches and results of the EC FP-7 projects MERASA (Multi-Core Execution of Hard Real-Time Applications Supporting Analysability, 2007-2011) and parMERASA (2011-2014) are presented. Both projects target timing analysable systems of parallel hard real-time applications running on a embedded multi-core processor. parMERASA investigates time predictable parallelisation for future embedded many-core systems with up to 64 cores.
