The 56002, and its code compatible siblings, would be a very wrong solution for a
commercial Vorbis platform. Since it will take a lot of work to get Vorbis
running on one, it seems pointless. Try a more realistic target processor. Does
anyone know which chips are popular in the commercial MP3 players? Most DSP
vendors are targetting a platform for MP3 players, but which ones are realling
seeing heavy use?
