A two level microprogram simulator
Ralf Petzold, L. Richter, H. P. Röhrs · 1974
This paper reports our current progress at the Department of Informatik of the University at Dortmund in investigating problems of dynamic microprogramming. In order to get a suitable tool quickly we decided to develop a corresponding simulator. The design criteria of a simulator for a two level QM-1-like microstructure are briefly described. Of primary interest are the methods for the serialization of time parallel events. Two different procedures are described. By means of the features of the used simulation language APL SV it was possible to achieve as well a flexible and easily extentable microprogramming structure as a convenient accessible model for problems of dynamic microprogramming at all. An example of a microprogrammed complete priority interrupt handling feature is appended.
