So for vision processing, you generally want to change the algorithims
from floating point to fixed point.

You may be interested in this project (called EmbedCV):
http://golem5.org/embedcv/
which claims to use fixed point.

This is on my list to look at, when I get around to playing with
cameras and whatnot, but I haven't used it yet.
