Pulse is probably trying to use floating point to do audio transforms.
These low end devices don't have a FPU. Software floating point is way
too slow and it eats 100% of your CPU.

mpd has been integer optimized on the NSLU2, it doesn't use float.

LP3180 and MPC5200B are low embedded processors with FPUs that are
easy to work with. You can get development boards for them here:
www.phytec.com but they aren't cheap.
