Mips64 assembly language

Code:

---


W = 1;
forever {
  if (n % 2 != 0)
    w *= x;
  n /= 2;
  if (n == 0)
    break;
  x *= x;
}

How To CONVERT This pgm TO MIPS64 ASSEMBLY LANGUAGE

I guess the first place to start is by locating a MIPS64 instruction reference, possibly on the web.
But your instructor should be able (and indeed should have already done so) to give you such a reference.

Then you can look up instructions for assignment, mul, div, comparisons and jumps.

Also, you could start by rewriting it into assembly pseudocode (not specific to any architecture, just generally assembly-like). For example:

Code:

---

# Calculate W = XN

set N =
set X =

set W = 1

loop:
    test bit 0 in N
    if clear, jump to okay
    multiply W and X, saving result in W
okay:
    multiply X by X, saving result in X
    shift N one bit down (right)
    compare N to zero
    if not equal, jump to loop

reminds me a bit of COBOL's verbosity.

Hey, that was uncalled for! ;) No need to insult, I was just trying to help someone learn.

When learning programming, it is important to learn how to express yourself in terms appropriate for the language. Assembly directives and opcodes are all very simple, performing just one simple action at a time.

I thought that breaking down a high level code snippet to the very basic operations needed to achieve the same results would be instructive.

Yes, you have to be careful with remarks like this or the whole thing can SNOBOL.
