There's very little memory in the FPGA. The FPGA is an Altera EP1C12, take a look at the data sheet for the details. > 2) what are those pins on the USRP (can they be used to connect a memory) If you can figure out how to interface to some kind of memory with the available 32-pins (assuming 1 Basic Tx, 1 Basic Rx) then yes. > 3) What happens to the usrp when i run a python code on it? is the code > something volatile like a RAM ?or is it loaded on the FPGA? No C++ or Python code ever runs on the USRP. All of that code runs on the host computer. Take a look at this: http://gnuradio.org/trac/wiki/UsrpRfxDiagrams Also, you may want to take a look at the USRP schematics.
