Based on your analysis in the previous step, deduce the reasons of the changes taking place in the registers. After the first OUT instruction is executed, a window showing the simulation of traffic lights will be displayed as shown in Figure 4.
#EMU8086 EXERCISES CODE#
Examine the contents of registers and their effects in the source code window. Observe and record the changes taking place every time you click this button. This will open the “emulated source code” window and a window showing registers, memory, and buttons. Understand the program by observing the program flow and interpreting the instructions in the source code. Select the “traffic lights” program from "file" -> "examples". įigure 3: Emulator Screen Exercise 3: Traffic lights program 1. Include all your observations and descriptions in your lab report. After the program is executed completely, an “emulator screen” window will be displayed as shown in. Examine the contents of registers and comprehend their effects in the source code window. Observe and record all the changes taking place every time you click this button. “MMU.asm” source code will be displayed in the window.
#EMU8086 EXERCISES DOWNLOAD#
(You can download the file from ECP2046 course content in MMLS to your local harddisk drive) 2. Select “MySource” directory and choose “MMU.asm” file. Click on the “file” menu and then on “open”. įigure 2: Emu8086 Tutorials Exercise 2: Load first program and analyse the operations 1. After reading and understanding the 8086 assembler and its operations, you are required to describe the above three sections using your own words in your lab report. Pay more attention to these three sections: part 6: arithmetic and logic instructions part 7: program flow control part 9: the stack 3. A screen as shown in Figure 2 will appear.

After the initial screen is displayed, you should click on the option to start 8086 assembler tutorials.
#EMU8086 EXERCISES SIMULATOR#
When the simulator starts, you should see the starting message “Loading” as shown in Figure 1.įigure 1: Emu8086 Loading. Click on the icon of Emu8086 to start the simulator. Exercises Exercise 1: Quick study of the simulator operations 1. Click button (or press F6) to see what happens when reversing those changes. Click button (or press F8) to step through the code one instruction at a time, observing changes in registers and the emulator screen. To run the code example in the emulator, click button (or press F5). All examples are heavily commented, so it’s a great learning tool. Select code examples from "File" -> "Examples". Execute Emu8086 by selecting its icon from the start menu, or by running Emu8086.exe. Emu8086 has a much easier syntax than any of the major assemblers, but will still generate a program that can be executed on any computer that runs 8086 machine code. Another advantage of 8086 instruction set is that it is much smaller, and thus easier to learn. This makes 8086 code very portable, since it runs both on ancient and on the modern computer systems. 8086 machine code is fully compatible with all next generations of Intel's microprocessors, including Pentium II and Pentium 4. Since your assembly code runs on a virtual machine, this makes debugging much easier. This completely blocks your program from accessing real hardware, such as hard-drives and memory. The emulator runs programs on a Virtual PC. It also provides views on Arithmetic & Logical Unit (ALU) that show the internal work of the central processor unit (CPU). You can watch registers, flags and memory values while your program executes.

Emu8086’s visual interface is very easy to work with. In addition, the instructions can be executed in a regular forward direction and also in reverse direction. All memory values can be investigated and edited easily. It shows the contents of registers, memory, stack, variables and flags. The emulator runs programs like the real microprocessor in a step-by-step mode. Introduction Emu8086 is an emulator of 8086 microprocessor (Intel and AMD compatible) with integrated 8086 assembler and tutorials for beginners. Objective To observe and examine the 8086 arithmetic, logical and program flow instructions set using the Emu8086 simulator. ECP2046 – Computer Organization and Architecture LAB: CO2
