I'm not sure what you are doing, but if you only want to play music, I'd use 
Ogg Vorbis instead, which has a decoder that only uses integer arithmetic for 
exactly the case of FPU-less machines and the Au1200. I could also imagine an 
MP3 decoder written for integer only being written somewhere, but I don't know 
anything about it.
