[hpsdr] NVIDIA Jetson Nano SBC - YouTube video

[Scotty Cowling]

Hi Scott,

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?

73,
