MIDAS: A MID-level language for microprocessors

ABSTRACT

The language MIDAS (MID-level ASsembly) has been developed to combine the efficiency of assembly languages with the structure and readability of high-level languages. MIDAS allows use of the full register set, flag set, and input/output and interrupt facilities of a target microprocessor, yet retains a basic structure similar to those of PASCAL and MODULA. This ability to access the full capabilities of a processor implies that MIDAS must be adapted to the particular microprocessor. Each adaptation takes the form of a dialect wherein the basic MIDAS framework is extended with “local procedures” and assignments. One such dialect, MIDAS/8080, developed for the 8080 microprocessor and implemented as a cross-translator on a CDC CYBER 172 computer, is described here. A proposal for MIDAS/6800 leads to the definition of a general framework for MIDAS. Finally, some recommendations for further work are presented.
