[Speex-dev] speex and omap

The example build in the TI directory is built using Code Composer.  There 
is a readme in the top level Speex directory that describes the process.  It 
is simple after you have installed code composer, and it runs directly on 
the TI simulator, using file I/O.  I am not using OMAP or DSP Gateway in my 
application, but it should work well for you.  I think that others would 
also want to use that configuration, so please tell us how this works out 
for you.  Maybe someone could provide an alternate example build that works 
with DSP Gateway, or you could do this after you have it working.  This 
would make it possible for future users to run Speex on their OMAP DSP 
without doing any DSP development at all.

For those that do not know, the OMAP series have and ARM core and C5x DSP on 
a single chip.  DSP Gateway provides a generic mechanism for communicating 
between the two.

There is no reason why you could not use the Linux ti_dsptools, but I have 
not done this, so I do not have a makefile for it.  There is a free 90-day 
evaluation version of Code Composer Studio, and you could use this to get 
things working, and switch over to ti_dsptools later if you choose.

There's already some stuff for TI DSPs in the ti/ directory. Also, I
recommend using the svn version, which has a few fixes for the C5x DSPs.
