Hi,
I'm building an application where I receive data from the x310, process the data, then transmit it out. I have 3 separate threads running, one for each task. The receive task is constantly receiving data from the x310 at 200MS/s and putting it into a buffer. The process task takes data from the receive buffer, processes it, and puts it into a transmit buffer. The transmit task is constantly transmitting data from the transmit buffer at 12.5 MS/s. I get constant underruns (U's on the console) when I try to receive and transmit from the same channel on the x310. However, when I transmit and receive on separate channels, underruns no longer occur. I would like to figure out a solution to this problem as I want to processes two 200MS/s streams on 1 x310. This problem occurs no matter the sample rates. I've tried lowering the receive rate to 50MS/s (while transmitting 4x the data to balance things out) and there are still constant underruns though at a lower rate. I know processing time is not the issue as I've profiled the time it takes to process, and I have even removed the processing task from the application altogether (receive data to a buffer and do nothing with the data; constantly transmit 0's from the transmit buffer) and the underruns still occur. I'm running on UHD 3.11.0, and the x310 is is configured with basic TX/RX daughterboards and flashed with the XG image for use over two 10 gig ethernet links. Thanks, Jason
