[speex-dev] Fixed-point update

[Jean-Marc Valin]

Hi,

Now that Speex is getting pretty stable, I have decided to make a
fixed-point/integer port the #1 priority. At this point, I'm looking for
help from people with prior fixed-point experience and/or a good signal
processing background. Anyone would like to volunteer?

I have already started the port by converting to int some of the most
used functions. While this should only have a small effect on the
encoder, I would expect the decoder to run much faster on processors
that don't have an FPU (e.g. ARM-based PDA). Can anyone with an iPaq (or
similar hardware) confirm that? The code is available here:
http://www.speex.org/misc/speex-1.1-int.tar.gz
Note that there is still lots of work to do before Speex is entirely
converted to fixed-point.

        Jean-Marc
