As it seems that the vorbis decoder is now stable with respect to
format/features, would it be time to start thinking about a hardware
implementation?
I would be interested in pursuing this if some there is consensus on
requirements.
If there is some enthusiasm for it then a module could be set up on the
opencores site for a gate-array decoder.

If I might add, I don't believe that there is a need for a hardware implementation. If MPEG-2 VIDEO "D1" *encoding* can be done in real-time on a 700 MHz Pentium III, Vorbis encoding and decoding should be able to be run on the same or lesser hardware unless you are thinking of a portable recorder/player. If there is interest in a portable player/decoder I would suggest TI DSPs, they are cheap, low power and should be powerful enough for Vorbis decoding (unless it is as complicated as DV Video decoding).

I am indeed thinking of the portable market. Like this design
http://www2s.biglobe.ne.jp/~elm/reports/mpc/report_e.html but instead of
using a MAS3507D mp3 decoder I would like to see an OggVorbis decoder chip.
true market acceptance is when these walkman style products are on the
shelves. They only get this cheap because of mass produced hardware
decoders, decoding it with a TI or other DSP is all well and good but the
one who makes an ASIC that does it makes more money. Doing a VHDL model and
running that in an FPGA is the only way a company is going to be willing to
take that step. An open design hardware Vorbis decoder will have every chip
manufacturer competing with each other for price.
Ultimately this means a cheap Vorbis Walkman/Rio style products.

TI and other DSP chips are actually not that expensive anymore. Most, if not
all, of the portable MP3 players use DSP instead of ASIC. You can even put
the decoding program inside the flash media, like the RCA Lyra. This way,
you can have Vorbis player almost instantly. Come to think of it, if someone
port the code to the TI 54xx platform, which the Lyra uses, then you can
listen to Vorbis encoded music on the Lyra.

Is there any possible way to play ogg files on a RCA Lyra 2820? I'm not too programming saavy, but if you could send me in a direction where I can get more information on this I would appreciate it, thanks.
