This has been done in a variety of ways for the USRP1, although there isn't much space free in the FPGA for new logic unless you are willing to sacrifice transmit capability or the number of receiver DDCs. The USRP2 has a much larger amount of free logic (~50% currently, may change) and was designed with the idea that people might offload the high rate portions of the signal processing chain, or even all of it, and run hostless. Of course, the effort to write HDL, verify in simulation, verify in synthesis, and debug with a logic analyzer is lot more than assembling blocks into a flowgraph in Python. -Johnathan _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
