Abstract:
For the design of microprocessor based systems in
an environment where the development systems are not available
the development of simulators seems to be essential.
The present work deals with the development of 8085 microprocessor
simulator on IB~1-370/115 mainframe. A powerful
command set has been designed to communicate with the simulator
for debugging purpose. Detailed study of intel 8085
microprocessor instruction set and its architecture has
been carried out for its modelling on the mainframe.On the
other hand study was also made to incorporate the microprocessors
8-bit words with the full/half words of the mainframe.
Finally a simulation program has been developed and
tested from the simulation algorithm. of the microprocessor
model.
