[hpsdr] [Discuss-gnuradio] Intel Atom is NICE.

[Robert McGwier]

The new I7 intel processors have a really amazing amount of horsepower
but a tremendous amount of onboard stuff is designed to work
intimately with the peripherals to bring on high speed graphics.  Now
if your argument is that all of this is going to be moved into the
GPP,  I might agree that we will see some of this.  If you are arguing
that the demand for an almost exponential increase in capabilities in
graphics hardware for the purposes of virtual reality and rendering
live and without memorex is not going to be happening, we are in
profound disagreement.

John, can you give me (and the others here) a pointer to the list of
GPIB, etc. devices your fantastic stuff currently supports?  I went
from seeing it in the early days with a handful of things supported to
seeing friends of mine (like W2GPS) running their labs with your code.
