[linux-audio-dev] things to port to the gp2x ..

i would wager that floating-point is not its forté, but rather than 
give you an opinion, what would be got a good float-performance 
benchmark that i can run on it to give you some real figures?  is 
there a preferred stdout-style C app i can run that'll give us some 
real figures?

also keep in mind its dual-processor; the second processor is 100% 
free to run code as fast as it can, while processor-1 is doing the 
linux thing .. so while floating-point performance may be abysmal, 
fixed-point math on the second CPU may just be fine ..

i wouldn't put this in the class of 'high-performance hardware', but 
more 'hardware worth squeezing every last bit of performance out of 
it'.

i don't think JACK would be wise on this thing, though i could be 
wrong .. its really designed to be a 'single-app running at a time' 
platform, and so far supports SDL/SDL_mixer, though you can do raw 
hardware i/o to the codec of course, and .. well .. there is the 
matter of USB-Audio Gadget drivers, which would provide a path to 
higher-power DAW upstream ..
