Abstract:
The fetch/execute cycle is an essential topic in the study of computer architecture. Common to both computer science and engineering, it is a method of describing the tasks performed by a processor within a computer. Although well established for many courses of study, it still proves troublesome to many but the most technical of students. Assembly language is often introduced as an aid to understanding the low-level hardware behavior. It is the aim of this project to create a graphical learning aid. To maximize potential use, a popular modem processor and assembler have been selected. The Microprocessor 8086 was one of the most widely used processors of its time. Virtual Microprocessor is a processor who works without taking the assistance from underlying microprocessor. lntel8086 uses segments like code segment, data segment, stack segment and extra segment; it also has different type of registers. For making this application we use visual C++, which gives us many features like GUI String handling, is easy visual Modeler more classes etc. Our application has Register parts, flag parts, memory and editor; we also show the results by some hardware devices i.e. stepper Motor and seven segments. This project aims to create a working assembler and graphical simulator to be used by technical students to gain a further insight in to the fetch/execute cycle. lll
