A few months ago, there was some discussion about adding fixed-point support for iPAQ's StrongARM to Ogg Vorbis (whether and how it's possible, that is). Has anybody tried this yet ?

[vorbis-dev] Re: [iPAQ] Ogg Vorbis fixed-point math anyone ?
Yes and no. I tried it but not seriously. I only went as far as floating point emulation, not trying to understand the algorithms and turn them to fixed-point/integer. I have been watching the ogg-vorbis lists though, and it would seem to be only one part of it that remains to be properly integerized. Unfortunately from the sounds of things it would take someone who really knew what they were doing to transform that last bit. I don't remember what it was, just that when I Googled for the definition what I found made very little sense to me. The emulation proved insufficient as the quality was way, way, way down. And the normal floating point emulation (e.g. the automatic stuff) wasn't fast enough. Ian.
