Question

Create a program that, given two inputs a and b, will output the following: • (a*b+b*3) Create a function that will perform this calculation, and use $a0 and $a1 as the argument registers, and $v0 for the return value. Ensure that you are able to call this function with additional statements before and after the call: for example, you may be asked to place an addi a, a, 3 call before the function is called, or to calculate the return of the function multiplied by 3, etc. This code is written in MIPs and has to do with functions I can't quite figure it out. it has been answered before but that code is incorrect.

Answer 1

Please find the code below::

.data
a : .word 2
b : .word 3

.text
main :
  
#setting parameter for function
lw $a0,a
lw $a1,b
jal calculataValue #call function
  
move $t1,$v0 #copy value from v0
li $v0,1
move $a0,$t1 #print a value
syscall
     
li $v0,10 #stop execution
syscall
  
calculataValue : #function definition
    mul $t0,$a0,$a1 #calculate a*b
    mul $t1,$a1,3 #calculate b*3
    add $v0,$t0,$t1 #calculate a*b + b*3   
  
jr $ra #return value

output:
