“…On the other hand, the hardware-software co-design problem is more complex in system development because the components need to be more advanced. The possibility of manipulating FPGA configurations at runtime using on-chip resources is investigated in [8,9]. The requirements for runtime partial reconfiguration capability in embedded applications can be sustained by storing multiple bitstream generation choices, including direct bitstream manipulation for logic blocks and hybrid one-dimensional and two-dimensional physical area relocation control modules.…”

The main goal of the proposed project is to enhance a mobile robot with evolutionary optimization capabilities for tasks like egomotion estimation and/or obstacle avoidance. The robot will learn to navigate different environments and will adapt to changing conditions. This implies the implementation of vision-based navigation of robots using artificial vision, computed with on-board FPGAs. The current paper aim to contribute on the implementation of a real-time motion extraction from video a feed using embedded FPGA circuits.

“…A model based approach is provided in (Krichen et al, 2010) to deal with software reconfiguration in distributed real-time embedded (DRE) systems with respect to non-functional properties. Authors started from the fact that MARTE and AADL standards present the limitation of permitting dynamic reconfiguration modeling for RTES by using only static sets of predefined modes (also called configurations) Online time verif.…”

Real time embedded systems (RTES) know a growing complexity due to modern applications requirements and architectures complexity especially with the addition of the multiprocessor feature. They are equally subject to a variety of constraints due to their mobility. They need to react to environment variability, resource limitations and timing constraints. An emergent solution to deal with this complexity is the integration of adaptation strategies in embedded systems design flow. The design space of multi-layer adaptation decisions is becoming increasingly vast and difficult to explore. Development of such systems at low system levels is therefore increasingly tedious especially with the limitations of computer aided design tools. Using MDE approach and the UML/MARTE profile for high abstraction level design is becoming a promising solution to ease the design of RTES. In the present paper we recall and classify existing works built around adaptive embedded systems. We concentrate on a set of criteria to help highlighting the shortages of existing approaches on modern adaptive RTES design. We focus on the design environment, adaptation features, online time constraints verification and performance assessment. Finally, we present our future works to cope with the limits of existing solutions while taking into account the observed criteria.
