A study of bus emulation. Application to M68000 based systems

With the important development of computer architectures, bus emulation becomes a very important tool. In this paper, methods for bus emulation are generally studied. We present several actual systems using this approach and introduce a new practical application. This application permits a PC-compatible system with an ISA BUS to control an embedded system originally based on a MC68000 microprocessor. This paper demonstrates the easy use of bus emulation techniques to modernize obsolete industrial controllers.Gobierno de España TAP93-044
