An Object-Oriented Visual Simulator for Microprogram Development

This paper describes an interactive microprogram development system, mainly concentrating on a software simulator. The system is constructed using the object-oriented programming language VEGA, and has some advanced features; (1) showing a simulation process on a graphic display (visual simulation), (2) coupling of the simulator and a microprogram editor, (3) multidirectional presentation of debugging information, (4) restarting the simulation from any time (back function). This paper shows machine-independent and flexible implementation for the above features. The system has been used for developing the horizontal microprogram of the super-mini computer MELCOM MX/3000 with a vector processor.
