[opus] Codec Implementation on Hardware

[Joshua Bowman]

If you use an Arduino Due, or any other ARM Arduino, your work is already
mostly done for you: https://github.com/Palatis/arduino-opus

I have no idea what the relative power of the TMS320C6713 is, I can't find
applicable benchmarks anywhere, but if its higher clock rate translates to
more real speed, you may be able to get better quality out of it. In this
case, you need to figure out how to import Opus code into its IDE, figure
out whether it has a useful FPU or not and build accordingly, then identify
any remaining hot points and develop algorithms optimized for the
architecture & compiler.

For a commercial project I'd recommend battle-tested ARM all day long, but
if you intend to research the state of the art, dipping into the unknown
with the TMS320C6713 is certainly a more interesting project.
