IFSys: an integrated framework for system-level synthesis

IFSys is an integrated system-level synthesis framework which allows a complete computer system to be specified using a set of high-level building blocks rather than behavioral level specifications. By reusing domain-specific design knowledge, alternative hardware and software configurations can be rapidly specified and synthesized. Thirty-two different embedded computer systems were synthesized using IFSys which spanned a factor of 1.5 in cost, 1.2 in power 2.2 in area, 1.5 in program size, and 21 in performance.
