Hi,
What happens to the incoming data from USRP, over the USB bus, when a
gnuradio block takes a lot of time to process its output? Is the data
buffered indefinitely or is it dropped as new samples come in case the
consumption rate is slow.
Thanks

GNURadio will indicates that overruns are occuring via the console. I
believe it is the u0 character.

That's what's called an overrun. Data gets
Is the data coming in the buffer FIFO? Is there a way to keep track of how
much data is lost?

Yes, the data are delivered FIFO.
In UHD, you can arrange for there to be timestamps on the data, so you
could look at the data and detect interruptions in the
monotonicity.
