You want to browse the 'Tremor' list archives. Tremor is the integerized 
vorbis decoder that people use for low-power applications.

There have been quite a few threads on the list about optimizing for 
different needs (CPU cycles vs memory usage, etc). See
http://www.xiph.org/archives/tremor/200403/0003.html
for example.
