Question

Write a MIPS assembly language program that adds the following two integers and displays the sum and the difference. In the .data section, define two variables num1 and num2 both words. Initialize num1 to 78591 10 and num2 to D5A 16 (use 0xD5A to initialize, Note that D5A is a hexadecimal number). Your main procedure/function should load the values of num1 and num2 into two temporary registers, and display them on the console window. Then add the values together, and use syscall for the print_int system call function to display the sum on the console window. Also compute the difference of two numbers and display it on the console window. (Reference: see Assignment 1) To print an integer on the console window, you must put the integer to be printed in the $a0 register, and the value 1 in the $v0 register. Then perform a syscall operation. This makes a call to the SPIM operating system which will display the integer in $a0 on the console window. Name your source code file assignment2.s.

Answer 1

You can modify this code

.data
msg1: .asciiz "Enter the first number: "
msg2: .asciiz "\nEnter the second number: "
result: .asciiz "\nThe result of addition is: "

.text
li $v0,4
la $a0,msg1
syscall

li $v0,5
syscall
move $t1,$v0

li $v0,4
la $a0,msg2
syscall

li $v0,5
syscall
move $t2,$v0

Add $t3,$t1,$t2

li $v0,4
la $a0,msg3
syscall

li $v0,1
move $a0,$t3
syscall

li $v0,10
syscall
