He dosnt have to, its hardware after all.
But why shouldnt he? The OpenMoko dudes would ;)

Thats your bussiness, AFAIK you can send a FPGA to sleep by tristating
some parts of it. Then you assign a PIN that listens to some sort of IRQ
and when the said IRQ occurs you remove the tristate mode from the rest
of the chip.
>Could FPGAs work with analog audio?
Sure, only thing you would need is some dumb A/D and D/A converter as a
FPGA is digital only, thats the drawback.
(I dont mind being corrected here, though!)
I just read trough the Xilinx webpage and trough the datasheet for the
Spartan but couldnt make out how much currency they realy eat.
Could someone state some nummbers here?
