Question

Problem 2: Arithmetic expressions [1.5 points] Write a program to evaluate the following function in u and v: 3u7uv- v2+1 Here, the variables u and v, are user inputs, and the program should receive them from the user at run-time. Then it should print the outcome computed as per given arithmetic expression. [To understand how to take the user input or write on console, please refer to the sample MIPS example programs). You are required to create and use two subroutines for this p Pay attention to the registers used for passing arguments to subroutine, and also the registers used for returning the output from a subroutine 1) int Square (a): Return a2. 2) int Multiply (a, b): Return a* b.

Program

#Data declaration section
.data
    #User input
    u: .asciiz "Enter the value of u: "
    v: .asciiz "Enter the value of v: "
    #result print
    result: .asciiz "3u^2+7uv-v^2+1= "
#Main method
.text
    #User prompt for u value
    la $a0,u
    li $v0,4
    syscall
    #Read user input
    li $v0,5
    syscall
    #store in s0 register
    move $s0,$v0
    #User prompt for v value
    la $a0,v
    li $v0,4
    syscall
    #Read v value
    li $v0,5
    syscall
    #store in s1 register
    move $s1,$v0
    #move u value into a0 register for function call
    move $a0,$s0
    #call square function to find u^2
    jal Square
    #Find 3*u^2 and store in s2 register
    mul $s2,$v0,3
    #Move v value in a1 register for function call
    move $a1,$s1
    #call function to find u*v
    jal Multiply
    #find 7*u*v
    mul $t0,$v0,7
    #find 3*u^2+7*u*v
    add $s2,$s2,$t0
    #put v value in a0 register for square function call
    move $a0,$s1
    #Call square function
    jal Square
    #find 3*u^2+7*u*v-v^2
    sub $s2,$s2,$v0
    #find 3*u^2+7*u*v-v^2+1
    addi $s2,$s2,1
    #Result display string
    la $a0,result
    li $v0,4
    syscall
    #Display result
    move $a0,$s2
    li $v0,1
    syscall
    #End of the program
    li $v0,10
    syscall
#Square function
Square:
     mul $v0,$a0,$a0
     jr $ra
#multiplication of uv
Multiply:
      mul $v0,$a0,$a1
      jr $ra

------------------------------------------

Output

Enter the value of u: 2
Enter the value of v: 3
3u^2+7uv-v^2+1= 46
