Re: [Discuss-gnuradio] What happens to incoming data if a block is too slow?

[John Andrews]

Is the data coming in the buffer FIFO? Is there a way to keep track of how much data is lost?

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

That's what's called an "overrun".  Data gets dropped.  The buffers are large, but not infinite.
