Question

In MIPS, write a program that asks the user to enter an integer and outputs the integer in 32-bit two’s complement binary. There should be a space separating each 4 digits.

A) Accept user input and display it without conversion
B) Convert the integer to binary without two’s complement
C) Convert the integer to 32-bit two’s complement binary with spaced digits
D) Display a message without accepting user input

Answer 1

The MIPS program that converts an integer to 32-bit two’s complement binary with spaced digits is option C.

Explanation:

Here is the MIPS program that accepts an integer from the user and outputs the integer in 32-bit two’s complement binary with spaced digits:

.data

prompt: .asciiz "Enter an integer: "

output: .asciiz "The binary representation of the integer is: "

.text

main:

# Prompt the user to enter an integer

li $v0, 4

la $a0, prompt

syscall

# Accept the integer input from the user

li $v0, 5

syscall

move $t0, $v0

# Convert the integer to binary

li $t1, 0x80000000

li $t2, 32

la $a0, output

li $v0, 4

syscall

loop:

beq $t2, 0, exit

sll $t3, $t0, 31

srl $t3, $t3, 31

or $t4, $t1, $t3

li $t5, 4

li $v0, 1

syscall

sub $t2, $t2, 1

sll $t1, $t1, 1

beq $t5, 0, newline

addi $t5, $t5, -1

j loop

newline:

li $v0, 11

li $a0, 0x0A

syscall

j loop

exit:

li $v0, 10

syscall
