Is anyone working on an Ogg Vorbis decoder that uses only integer arithmetic? Would it be hard to do? It will be required at some point (for example, many portable MP3 players are based on an ARM processor without the floating-point coprocessor), but I don't claim that now is the time to start work on such a thing. I'm just curious.

I'm just curious.I'm currently working on converting libvorbis to fixed point arithmetic. I've managed to get all the decoding after the MDCT reverse transformation into 24-bit fixed point, including the windowing. -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.
