.. unless you put such DSP code in certain 'key infrastructure' 
components of the system ..

its amazing though, how there are good quality examples of audio/DSP 
code which don't require FP .. which do in fact use integer/fixed 
point math .. and which function just fine in cheap hardware ..

oh, so can i, for sure.. i mean, if you've taken the easy path once, 
no need to consider any other path twice .. except to bemoan the 
existence of such other paths, of course ..

regardless, there certainly seems to be potential in the GP2X' lowly 
cpu's for interesting audio hacking, and i certainly hope its 
acceptable to the cognescenti to recognize this fact, FP or none ..
