Well, we are trying to teach AI, not embedded systems :) Towards that
end, we've sort of tried to simplify things as much as possible for the
kids who are taking the class, since most of them will probably never do
an embedded system again. That means doing things (like floats) that are
commonly available on "real" machines. I think at least one person will
tackle the task of converting the work to fixed point (among other
things) to reduce processor time and overhead as a final project. I'll
keep you up to date.
