Hi Scott,<br>
<br>
You make a good point. This is one of the things I would like to do
with the new TAPR TangerineSDR. We should be able to essentially do
all of the filtering and demodulation in the FPGA, and let the SBC
just do command and control and the GUI. Another (good) side effect
of this might just be reduced latency, since the FPGA can likely
perform the DSP tasks more quickly than a (relatively) slow
general-purpose CPU can. Of course, maybe the Cuda cores could do it
fast enough just by splitting the software into two pieces as you
suggest, and using the GPU for part of it and the CPU for the rest.
If Phil can do a massive FFT in real time with the Jetson board, why
not have it demodulate and filter a narrow-band signal in real time?<br>

<div>These embedded computing platforms would have a lot more
merit if someone where to split PowerSDR/Thetis into thin
client/server pieces, and the server could run on the
inexpensive but reasonably powerful embedded platform. Alas,
no one has taken on this challenge (and I can't because I'm
not a software developer). Because I set the bar for radio
functionality at the "PowerSDR or better" level, unless and
until someone comes up with something that really is better,
functionally not philosophically, then to me a Windows
platform remains a must-have.</div>
