Microprocessor simulation is one of the recent applications of computer design.It Collections is used for emulating the microprocessors for some purposes such as; learning microprocessor structure and assembly language in laboratories in universities.In this research simulation for the microprocessor Intel 80386 was suggested, designed and Marinade implemented.
Implementation was verified for some data transfer instructions like MOV instructions in deferent addressing modes.The designed simulation program was implemented using Visual Basic programming.Examples were tested successfully for some MOV instructions.
