A macromodular systems simulator (MS2)

Abstract

The macromodular systems simulator is a control program and programming language implemented at Washington University to facilitate the design and subsequent realization of macromodular computer systems. The MS2 control program and language enable an engineer or programmer to describe macromodular systems and run programs on such systems simulated on a conventional digital computer (IBM 360/50). Input to the simulator consists of a standard set of function definitions for the basic macromodules, a description of the organization of the target machine, the program to be executed by the target machine, and data required by that program. Output from the present version of MS2 is a level change map (a continuous trace of the internal control network of the target machine as it executes its program) and the results of computations performed by the target machine. A procedure for preparing wiring tables and diagrams has been developed and will be incorporated into an improved version of the simulator.
