[hpsdr] Calculating engine

[Michael Cozzi]

     Hi Jim,

     Depending on the video cards involved- CUDA might be a possibility. 
GeForce 600 and 700 series cards are CUDA capable. Driver support is 
still happening as well.

     Considering the formidable power of a GPU, I'd venture to say that 
even older GPUs will work for signal processing just fine.

     If they are AMD cards- all bets are off. Unless future ham software 
supports OpenCL.
