Designing formal reconfiguration control using UML/MARTE

This paper presents the first framework to design and synthesize a formal controller managing dynamic reconfiguration, using a Model Driven Engineering methodology base on an extension of UML/MARTE. The implementation technique highlights the combination of hard configuration constraints using weights (control part) - ensured statically and fulfilled by the managed system at runtime - and soft constraints (decision part) which, given a set of correct and accessible configurations, choose one of them. An application model of an image processing application is presented, then transformed and synthesized to be executed on a Xilinx platform to show how the controller, executed on a Microblaze, manages the hardware reconfigurations.
