This paper presents an extension of our AAA rapid prototyping methodology for the optimized implementation of real-time applications onto reconfigurable circuits. This extension is based on an unified model of factorized data dependence graphs as well to specify the application algorihtm, as to deduce the possible implementations onto reconfigurable hardware, in terms of graphs transformations. This transformation flow has been implemented in SynDEx 1 , a system level CAD software tool.
