|Subject:||Latency Management in GnuRadio with Hardware Buffers|
|Date:||Thu, 18 Nov 2021 13:09:42 +0000|
However, the hardware buffers are not included right now which leads to an increased latency if the FG is run with Hardware (B210 USRP). An overview of the setup is attached.
Matt spoke about the possibility of adding functionality to UHD such that it reports the actual time a certain tagged sample has been processed and sent to the DAC. From what I have seen by looking through the documentation this feature is not available but maybe I missed something there and you can point me in the right direction.
Are you aware of any other ways of including the hardware buffers of a USRP in such a control loop?
I would also appreciate any further insights regarding this topic and how other GnuRadio users are approaching latency minimization in GnuRadio with USRPs in the Flowgraph.
