Exploration de l'espace de conception des architectures reconfigurables

During many years, the designers just had two possibilities to design embedded systems; microprocessors and/or application specific integrated circuits. Nevertheless, a new possibility has appeared lately, the reconfigurable circuits. These systems have an important lack of tools at all design levels. Designers are then facing the difficult task of designing their target reconfigurable architectures, which is a critical issue since it can strongly affect the final system performances. To help them in that task, it is necessary to develop tools that enable an efficient design space exploration. With such tools, designers could improve synergy between application and architecture and then choose the best one for their application. In this article, we propose a design space exploration method for reconfigurable architectures dedicated to data intensive applications. The design space exploration takes place at the first stages of the design flow before any architectural definition.
