Manually exploring the potential parallelism of an application deployed on multicore architectures is greatly time-consuming. This paper presents an open-source Eclipse-based framework which aims to facilitate the exploration and development processes in this context. The framework includes a generic graph editor Graphiti a graph transformation library SDF4J and an automatic mapper scheduler tool with simulation and code generation capabilities PREESM . The input of the framework is composed of a scenario description and two graphs one graph describes an algorithm and the second graph describes an architecture. The rapid prototyping results of a 3GPP Long-Term Evolution LTE algorithm on a multicore digital signal processor illustrate both the features and the capabilities of this framework.
