Embedded systems based on dynamically reconfigurable FPGAs allow hard ware accelerators to be swapped at runtime. This technique enables to reduce the size of FPGAs in embedded systems, reducing manufacturing costs and energy consumption. From then on, new challenges of architecture design and management arise, in order to make the most of this technique. Guarantee of service execution should be observed as embedded systems applications have changing compu tational needs, and the time complexity of resource allocation algorithms introduce latency overheads.The objective of this thesis is to propose a methodology for managing the allocation of hardware resources to guarantee a minimum level of service of an application. A quality model is ...
