Amit, I strongly suggest you do the work to acquire a basic grip on how GNU Radio and the USRP work in their normal configuration before you attempt to hack the FPGA code. Dawei Shen has put together a nice set of tutorials that will get you started: http://www.nd.edu/~dshen/GNU If I & Q processing is not clear to you, please see any of a number of DSP and digital communications text books. Several are listed at http://comsec.com/wiki?SuggestedReading With regard to data transfer across the USB, once you've opened the USRP and enabled it, the data streams across the USB. This is all handled for you by the standard software. No user visible interrupts are involved. If you want to develop an understanding for how to talk to the USRP without using GNU Radio, start with usrp_standard.h and usrp_basic.h in usrp/host/lib. That's the high level C++ interface that GNU Radio uses.
