I did quite a bit of experimentation with the 770 dsp back in late
august.   As a point of clarification, the dsp in the OMAP 1710 (used
in the 770) is just a TI *C55x, *which is already supported by speex
as far as I can tell.    Thus, getting speex to work on the 770 should
mostly be an issue of adapting the he exisiting speex C55x port to the
build process using the free dsp tools, or TI's code composer; and
writing appropriate wrappers to move data back and forth across the
ARM to DSP boundary using the linux dsp gateway interfaces.     

I'd be happy to try and help anyone who might be interested in
attempting such an endeavor.
