Hi there, any help with the following would be greatly appreciated. Context in the image:

Assume a register-based protocol for the function call. Show how this is achieved. You can assume
– call-by-value;
– variable v is stored in register $s0;
– variable f is stored in register $s1.
Explain if a stack frame is required, and justify your answer.

Consider the following function that computes the factorial of the
given (non-negative) number:
function fact(int x) {
int res := x;
if(x > 1) {
X := x - 1;
res
res * fact (x);
:=
}
return res;
}
and the following code that calls this function:
int v := 5;
int f := fact (v);
