Abstract : Application Architecture Adequacy (AAA) aims at tuning an application to a given hardware architecture. However it is still a difficult and error prone activity. As like as in Hardware/Software co-design, it requires a model of both the application and the architecture. With the new highly-parallel architectures, AAA should also allow a fast exploration of different software mapping granularity in order to leverage better the hardware resources without sacrifying too much productivity. The main contribution of this paper is to extract from a case study a methodology based on dataflow modeling to make the software both faster to develop and suited to the target. Then we show how this methodology can solve some of these issues.
