Re: [Discuss-gnuradio] What does the onboard FPGA now and how can I realtime process the signal?

Yes, I knew that. That will be a really great improvement. I've been waiting for that. :) But I don't know when it'll be ready for all of us. ;P How about the time schedule?

As part of the "message block" effort (m-block), we'll be supporting
precise timing.   This impacts the host and the FPGA, and will provide
time stamped input and "do not transmit until time t" output.

One of the use cases is TDMA.

The timing resolution will be determined by the master clock in the
FPGA, currently 64MHz.
