The ARAVIS project aims at addressing the challenges raised, both at the hardware and software levels, by the production of highly integrated multiprocessor systems on chip (MPSoCs) designed for demanding applications such as video encoding/decoding and software-defined radio communications. Due to the complexity of the manufacturing process, the latest generations of chips exhibit peculiar features that must be taken into account : (i) massively parrallel processing units, (ii) irregular behavior and aging of the processing units due to unavoidable defects of the manufacturing process. The ARAVIS project strives to provide a hardware and software platform suited to the adaptation requirements raised by the needs of such emerging hardware technologies and applications. The proposed approach encompasses three contributions: (i) a symmetric hardware architecture based on an asynchronous interconnect with integrated voltage/frequency scaling, (ii) a set of regulation algorithms based on control theory to optimize quality of service and energy consumption, (iii) a component-based runtime environment and related software tools to ease the dynamic management of applications and execution resources.
The project partners are STMicroelectronics, CEA-LETI, TIMA and INRIA (Necs and Sardes project teams). The project runs from October 2007 to September 2011.

The MIND project aims to develop an industrial technology for component-based construction of embedded systems, based on the Fractal component model.
This includes the development of programming languages (extended C, ADL, IDL), a chain for compiling software architecture descriptions and generating code, and a graphical IDE integrated to Eclipse. In addition, the project aims to study extensions and refinements to the Fractal model suitable for dealing with non-functional aspects such as real-time and priority constraints, the model-based control of dynamic reconfiguration of components, and its integration with the BIP component model developed at the Verimag laboratory.
The project partners include STMicroelectronics, CEA, INRIA (Adam and Sardes prokect teams), Schneider. The project runs from October 2008 to may 2011.
