What sort of connection exists between the Overo and the rest of the
system (e.g. is this using USB, high speed serial, etc.?)? In
particular what sort of bandwidth is possible from the
ADC->FPGA->Gumstix. Obviously the larger FPGA allows for some extra
signal processing to be done before the gumstix, but does the gumstix
then see the mainboard as an USRP1-like source (i.e. 16-bit samples @
8MS/s), or is the bandwidth/bits-per-sample easily adjustable?
