I'm a bit of a fence-sitter on using FPGAs for SDR. At what point does it become Hardware Defined Radio again? But I suppose that with a good compiler, and FPGAs that can be re-programmed a large number of times, it counts as SDR :-) I'd love to be able to compute wide-band total-power and *insanely-huge* FFTs as fast as the A/Ds will go. That isn't going to happen with a garden-variety compute platform in the next four years. But a parallelized FFT inside an FPGA(s) or a GPGPU could likely tackle this without breaking into a sweat.... -- Marcus Leech Principal Investigator, Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
