32 bit integer square root

Hi all,
I know this has been asked before on this forum, and someone actually
had one, but I've not been able to contact the author of the response
to the previous post.

I'm in need of an assembly language version for the 5509A. I don't
need the precision of FP, just unsigned ints. I've tried all the C
algorithms that I can find and none of them are fast enough for my
application (best so far is about 2.2uSecs @ 200MHz).

So, if anyone has one, I'd sure be appreciative.
Thanks,

Why do you think it's slow for a C55x? I've tried hard to get it run
in 775ns non-vectored on an 200MHz C64xx...
