Possible, yes, but the FPGA does not have any "hard" multipliers, so you'll need to use logic cells for that.

We can easily do thousand point FFTs on 8 MS/s data streams. > I don't have any experience in FPGA programming, > just wondering if it's possible. > > Best regards, > Jens > > > > _______________________________________________ > Discuss-gnuradio mailing list > [email protected] > http://lists.gnu.org/mailman/listinfo/discuss-gnuradio > _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
