Abstract: This paper introduces a template architecture for codesign methodologies. This architecture is based on a data synchronized control scheme that is well adapted to the implementation of numerous telecommunication applications specified with a data frow model:The template architecture permits an easy integration of HW and SW coarse grain units. Communications between internal units are assumed to have an asynchronous protocol that is the more general transfer mechanism but also the more ex-pensive in hardware resources. Hence, a communication synthesis method is presented that transforms asynchronous communications into synchronous ones. Results on an acoustic echo canceller illustrate the interest of the approach. 1.
