Interesting. Well, I'd start at the top level:
http://gnuradio.org/trac/browser/gnuradio/trunk/usrp/fpga/toplevel/usrp_std/usrp_std.v
If you need no cordic, CIC or halfband filter, just rip out the entire
RX chain and place your algorithm there. The raw ADC samples are
rx_a_a/b and rx_b_a/b.
Sounds like fun. Good luck!
