The FHDL macro processor
Peter Michael Maurer · 1990
The FHDL (Florida Hardware Design Language) Macro processor provides a mechanism for extending the language features provided by the other components of the FHDL system (the ROM language, the PLA language, and the logic specification language). The primary use of the Macro processor is to provide flexible cells, such as ripple-carry adders, that can expand to match the size of the interface. The use of the Macro processor for this purpose is transparent with more standard hierarchical specification mechanisms. In addition, the Macro processor was designed to be an implementation vehicle for more sophisticated hardware specification and synthesis systems. The Macro processor provides most of the features found in other macro languages, and provides several new features that are found in few, if any, existing macro languages. The use of the Macro processor for high-level synthesis is the subject of much on-going research.
