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!
