Lab Instructions
Whether an experiment contains one or
several practicals /programs
Several
practicals / programs
?
 Lab Teacher forms groups of the students based on
One
practical / program
All Students need to perform the
practical/program
 Assign all practicals /programs among all groups
 Teacher decides whether the completed practicals / programs can be appropriately described
using flow chart, algorithm, query statement, etc.
 Teacher issues necessary instructions to the students for writing practicals / programs
accordingly
 Students write experiments in practical files and get them signed by the lab teacher
 Students make entries in the list of contents of the practical files and get them signed by
the lab teacher
Whether practical has been verified
and signed by the lab teacher?
?
 If a student has not completed a practical, he/she is expected to complete it at his/her
own with the help of his/her fellow students in his/her hostel
 The student completes the practical file and submits it to the concerned teacher in
his/her office or mail box on next working day
 In case of an experiment containing several practicals, a lab teacher needs to think whether a
practical performed by the students in one group needs to be repeated by the other groups in lab on
the same day?
OR
A practical performed by the students in one group needs to be repeated as assignments to be
completed by the students of other groups in their hostels? Here, an assignment includes both
executing a program on computer and also writing the same in practical file.
OR
A practical performed by the students in one group needs to be repeated as assignments, only
writing practicals in their practical files, for the students of other groups in their hostels?
 Teacher issues necessary instructions to the students accordingly.

Instructions
The advance microprocessor lab experiments are designed for 32-bit programming by using
Microsoft Macro Assembler MASM 6.15. The objective of designinig this lab manual is to make
programming more efficient and productive.This lab manual includes various experiments as
well as its variants also, some of the experiments are mandatory for every students but if a
program has its variants than alternatively a students have to execute only one variant. This
makes our lab classes more interesting. Our objective is to learn 32-bit programming by using
simulator. In this we are using Microsoft Macro Assembler (MASM) 6.15.
The Microsoft Macro Assembler (MASM) is an x86 assembler that uses the Intel syntax for
Microsoft Windows. There are two versions of the assembler - 16-bit and 32-bit assembly. The
Microsoft Macro Assembler has many macro features that make 32-bit programming much
easier to learn. Microsoft Macro Assembler (MASM) 6.15 is an integrated software package
written by Microsoft corpration exclusively designed for 32-bit programming.
We are using a library called link library for basic input-output operation. Two versions of the
link library exist that were originally developed by Kip Irvine. The 32-bit version is called
Irvine32.lib and works in Win32 console mode under MS-Windows, while the 16-bit version is
called Irvine16.lib and works under MS-DOS. Here, we are workng in Irvine32.lib.
The following are the steps to use MASM 6.15:
Step1: Download MASM615.exe, a self-extract executable file, fromhttp://www.ccse.kfupm.edu.sa/~mudawar/coe205/lab/index.htm
Step2: Installation can be done in following way:
 Double click on MASM615.exe to extract the files.
 Specify the installation directory.
 Use C:\Program Files\MASM615 as the destination directory.
Step3: Define an environment variable MASMDIR for the installation directory:
 Under Control Panel, double-click on System to obtain the System Properties dialog
box. Under System Properties, click on the Advanced tab. Click on the Environment
Variables button.
 Under Environment Variables, Click on the New button to add a New System
Variable. Add MASMDIR as the variable name and the C:\Program Files\MASM615
1
as the variable value and press OK.
 The MASMDIR variable and its value should now appear under System Variables. If a
different installation directory is chosen for MASM 6.15 then specify it in New System
Variable – Variable value.
Step4: Edit the Path system variable by inserting %MASMDIR%; (don't forget the semicolon)
at the beginning of the variable value.
Step5: Define a new system variable called INCLUDE with value %MASMDIR%\INCLUDE
and press OK. This variable specifies the directory that contains the include (.inc) files.
Step6: Define a new system variable called LIB with value %MASMDIR%\LIB and press
OK. This variable specifies the directory that contains the link library (.lib) files.
Step7: Check the environment variables. Open a Command Prompt and type:
• SET MASMDIR
• SET INCLUDE
• SET LIB
• PATH
These commands should display the MASMDIR, INCLUDE, LIB, and PATH environment
variables. If the installation steps are done properly, you can start using the MASM commands.
Experiment 1
I.
Write a program to read a 32-bit integer, store that number in EAX register and display it digit
by digit.
II.
Write a program that uses a loop to input ten signed 32-bit integers from the user, stores
the integer in an array and redisplays the integers.
Experiment 2
I.
Write a program that generates and displays 20 random strings each consisiting of 10
random capital letters {A,…Z}.
II.
Write a program that displays a single character ‘*’ at hundred random screen locations.
Use a delay of 100 milliseconds before displaying the ‘*’ at the next random screen
location.
Experiment 3
I.
Write a program that reads two one-digit numbers and output the maximum of two.
Extend the program to read three one-digit integers and find max.
2
Experiment 4
I.
Write an assembly program to perform addition, subtraction, multiplication and division
of two 32-bit numbers.
II.
Write a program to find GCD of a given two 32-bit numbers.
III.
Write a program to find square and cube of a number.
Experiment 5
I.
Write a program to check whether a given string is palindrome or not.
II.
Write a program to reverse an input string.
Experiment 6
I.
Write some programs which uses multiple data segment and multiple code segments. Do
these programs by defining segments in different files and link all of them to get the
desired output.
Experiment 7
I.
Write a program to implement a rolling display of characters using display interface.
Experiment 8
I.
