[Discuss-gnuradio] FX2 firmware

[Dominik Auras]

Hi all!

I am studying the FX2 firmware provided by the USRP package, just to 
"get a feeling" for this.

There are a few very old mails on the mail archive stating that an 
improvement of the USB bandwidth could be possible if the FX2 timing is 
tuned. Does anyone know where the current bottleneck is? Is it the main 
loop, or the GPIF state machine?

There was an idea about moving the loop invariant, e.g. one loop only 
for tx if only tx chain is enabled. However, my first quick'n dirty 
trial didn't change anything (test_usrp_standard_tx to test). At least 
it still works :)

It will do to point me in a good direction, I'll find out the rest. 
However, it would be faster if someone can direct me.

Best regards
Dominik
