Yes, the reference encoder should work in realtime on a system like
that. Note that's it's not especially well-tuned for 8 kHz audio; most
people use it at 48 or 44.1 kHz. It will work though.

You might also be interested in the new Opus codec we're developing.
It's somewhat higher complexity, but offers superiour compression and
the reference implementation includes a fixed-point encoder, which may
make up for the complexity difference on XScale.
