Question

Computer Architecture:

Write a MIPS program to compute f = g - (f + 5)
Assume registers $to, $s1 hold values for g and f respectively.
The program should display the following prompts and read value entered by the user “Enter a value for f:"
“Enter a value for g:"
The program the prints: "Answer for f = g - (f + 5):"
The program should repeat the above steps 3 times for each input pair, f and g

Make certain that your assembly code is properly organized (indented, commented, contains your name at the top of the code). Comment any assumptions at the top and include results showing the working code via screen prints

Dear Student,

I hope the following code fits in your needs.

# Space left to add name of the student

.data
    msg1: .asciiz "Enter a value for f: "
    msg2: .asciiz "\nEnter a value for g: "
    result: .asciiz "\nAnswer for f = g - (f + 5): "

.text
    li $t2,5
    li $t3, 0
    li $t4, 3
    Loop:
        beq $t3, $t4, Exit
        # Taking input from user for f
        li $v0,4
        la $a0,msg1
        syscall
        li $v0,5
        syscall
        # moving the value of $v0 to $s1
        move $s1,$v0
        # Taking input from user for g
        li $v0,4
        la $a0,msg2
        syscall
        li $v0,5
        syscall
        # moving the value of $v0 to $t0
        move $t0,$v0
        # calculating the value of the given formula
        Add $t1,$s1,$t2
        sub $s1,$t0,$t1
        li $v0,4
        la $a0,result
        syscall
        li $v0,1
        move $a0,$s1
        syscall
        j Loop     #jumps back to the top of loop
    Exit:       # ends the program
        li $v0,10
        syscall
