[Vorbis-dev] RE: Vorbis-dev Digest, Vol 8, Issue 7

Martin, hi,
Also my first words to this list.
I ported vorbis 1.0 decoder to our company owned DSP core, it costs about 40 
MIPs
for worst case decoding. This is full assembly implementation.
I also heard there's ARM implementation with about 70Mhz.
Good luck to your projects!

Regards,
SeanS
