Question

1) Write a MIPS Procedure (code) to compute x^n, if n >= 0, $a1 = x, and $a2 = n

Answer 1

# Assuming $a1 = x, and $a2 = n and result is stored in $v0

addi $v0, $zero, 1  # set result to 1
for:
    blez $a2, end
    mul $v0, $v0, $a1   # result = result * x
    addi $a2, $a2, -1   # n = n-1
    j for
end:
