'Tremor' is xiph's fixed-point decoder. It also has a branch called
Tremor-lowmem, specifically designed for low memory footprint.

Whilst for a cell SPU the fixed-point thing isn't particularly useful,
the design of the decoder in other ways is appropriate for any
low-memory system. Also, Tremor-lowmem will probably run just fine on
an SPU anyway, even if it's not using the floating point hardware...
