Model-driven Deployment Optimization for Multicore Embedded Real-time Systems : the OptimAll Approach

The power of modern embedded systems is continuously increasing together with their complexity, thereby making their development more challenging. In the specific case of the adoption of multicore solutions, while processing power is heavily increased, the issue of allocating software tasks to specific cores on the target platform arises. In this paper we introduce OptimAll, an automated model-driven approach that aims at providing support in the delicate phase of task allocation at design time. Besides introducing the entire approach, in this work we focus on the automatic generation of a suitable input to the task allocation optimization mechanism from a UML–MARTE system design model, as well as on the actual optimization mechanism and its outcomes in relation to the design model elements.
