This paper presents the underlying methodology of Cosmos, an interactive approach for hardware software c o-design capable of handling multiprocessor systems and distributed a r chitectures. The approach covers the co-design process through a set of user guided t r ansformations allowing semi-automatic partitioning. The transformations are b ased o n a p owerful set of primitives for functional partitioning, structural reorganization and communication transformation. It leads to a fast
more &raquo; ... ation of a systemlevel speci cation into an architecture with a short design time and fast exploration of design space. The application of this approach is illustrated using a design example starting from a system-level speci cation given in SDL to a distributed hardware software a r chitecture described in C VHDL. We show that the use of transformational approach allows: 1. Application of the expertise of the designer during partitioning; 2. the user to understand the results of the co-design process; 3. the process to take into account partial existing solutions; 4. large design space exploration; 5. the designer to start from a very high-level specication language of the system to be designed.
