A complete specification and implementation methodology for high-level hardware transformations

The complexity of modern digital systems requires complex design entry methods and thus, language based designs are often an appealing alternative for schematics. Language based design entry supports high-level design transformations, through formal and executable traditional compiler construction problem specifications, their main advantages being modularity and declarative notation. In this paper, this idea is exploited under a pow erful compiler construction system and a methodology is given to design executable high-level transformation definitions. In effect. this methodology stands as a meta-level between hardware transformations and their implementation and can be valuable in fast evaluation of new ideas and techniques.
