[Discuss-gnuradio] Free USRP FPGA Resources
Dear Matt, Dear All, Is the DDC decimate by 2 half band filter built inside the FPGA ? If it is so, then how much the free available FPGA resources left after building all the present USPR circuits in it? I mean, is there a free space to modify the CIC + HBF circuit and to build a complete DDC block (CIC + CFIR + PFIR) ? Thank you in advance.

The standard USRP build has about 95% of the LE's used up, but a decent amount of memory free. If you plan on using only 1 complex RX path and 1 complex TX path - you can remove quite a bit of logic and build with a single side enabled. Thank you in advance.
