[hpsdr] Potential New openHPSDR Project

[Hermann]

Dear Phil, All,

this will be a great project, and if I can help I would be glad! I
guess a dedicated DSP processor like this would surely outperform what
I am currently trying with the Cuda approach (if you only want to
compare performance regardless of the differences between a PC- or a
standalone approach), simply because we are working on relatively
small data chunks - as Jeremy already pointed out.

Vy 73,

P.S. [OT] I hopefully come to end for my CudaDSP project soon, but the
recently published Merc/Ozy code for 4 receivers clearly shows the way
what I want to do next (and, of course, waiting for OzyII !!), and
there is still the idea using Cuda for the graphics part (sprectra,
etc.). I will give a wrap up of my "experimentation" then, hopefully
showing in which way some parallelism on your GPU might be useful for
HPSDR.
