Yeah. It's a tough life, being smart!

I had been thinking just simple arithmetic. I'm writing some material
and wanted to know what to mention. I'm at a disadvantage because to
date I've always just rolled that sort of stuff myself.
Who's "us" and do you have a website?

If you are looking for basic math routines and simple filter, there are
enough free libraries available all around.Even TI allows you to download
many of these libraries.Additionaly to implement basic math(like add,
subtract, multiply, square, square root etc.) in fixed point you could use
the file basic_op.c found in G.72xx packages.
On the other hand if you are looking at *correct*, commercial grade,
hand-optimized fixed libraries like trignometry etc. then you could buy it
from companies like sundance,microprocessing.iwarp.com and us. I will be
willing to discuss with you further if you are interested in buying it
from us.

That's actually the IQ math package from TI, and it allows all ranges
from 2.30 to 31.1.
P. J. Plauger of Dinkumware (www.dinkumware.com) said they have done a
fixed-point package conforming to the draft C standard extension for
embedded systems/DSPs. I have not seen it or tried it, so I can't
really comment on it. I do not know what, if any, platforms with
hardware support it might have been ported to. Contact them if you
are interested.

I know that TI offers a fixed-point arithmetic package for use with the
'28xx processors (they call it their "Q15" or "Qxx" package). Does
anyone know of any other vendors that offer this?
