[hpsdr] SHARC samples

[KD5NWA]

I'll file all this information in the future projects file, seems 
like a very useful chip in the arsenal against evil bits.

I looked it up on Digi-Key and there is only one listing for the LQFP 
200MHz part a@ $28.89 qty min 13 ouch, but that will change soon it's 
a brand new part. The price is pretty good considering the speed of the part.

I've played a little bit with the DSPic chips and they are also easy 
to work with but have the limit of 16 bit integer. If I ever decide 
to put a Pic in a project it will be one of those chips they are not 
expensive. But when horsepower is needed then the AD part of a Xilinx 
FPGA is the ticket.
