[opus] Developing OPUS on TI CC3220

[Jean-Marc Valin]

Hi Vince,

Normally, Opus should work fine on the CC3220, though real-time encoding
may be a bit tight depending on what configuration you choose. You'll
probably want to configure with --enable-fixed-point and
--disable-float-api (or define FIXED_POINT and DISABLE_FLOAT_API if you
don't use autoconf).

The encoder has a bunch of run-time settings that you may want to set,
depending on your application. These include bitrate, complexity
(probably a low setting for that that chip), and bitrate management
(CBR/VBR/CVBR).

In the end, aside from the complexity requirements, you should need to
do anything special to get Opus running on your chip.

Cheers,

	Jean-Marc
