The rbf file is an FPGA configuration file for the altera FPGA in the
USRP1. My understanding is that a VI is a program that runs in the
labview runtime environment. Not related.

   Thanks josh regarding the VI programming , yes it does run on labview , so what i can do with
this part of my problem is that , i can think of generating a .so library which does the work of interacting
/talking to my device and by importing this files in my gnuradio block i could think of integrating with my
gnuradio custom block.
Hope u understand my point , and i highly apologise if my thinking is wrong.

100% possible

Any arbitrary hardware can work with gnuradio. You need to write a class
in C++ that inherits from a gr_sync_block and talks to your device. Are
you willing and able to do that?


-- another option --

Some people use a named pipe to share streaming data between a gnuradio
file source/sink and another software environment that produces/consumes
the samples.

thanks for your guidance .
