Model of 8-bit microprocessor intended for lecturing

Study of architecture and basics of digital computers is part of IT studies performed today. In order to present high quality lectures and learning materials to students, model of 8-bit processor was created. It is simple enough to allow detail realization study during scheduled lecturing units. In this paper such a model is presented with microprogrammed control unit, implementing also stack and interrupts belonging to more advanced topics. Internal implementation of the model contains registry addressing, ALU, microprogrammed control unit and communication with memory.
