Bob,
I just placed my order with Newegg, this looks like a fun little
project. I assume with only one slot, which is needed for the firewire
card, that dual monitors is not possible???
Where can I find glxgears??? Is it freeware???

Subject: [Flexradio] Intel Atom is NICE.
I am running GnuRadio, SDRMAX, and PowerSDR on my new Intel ATOM 330
MiniITX motherboard. I had to put a firewire card in the single PCI
slot.
The integrated intel graphics are nice and spiffy (glxgears is at 800
fps if
you turn off the desktop enhancements, no wiggly windows please).
At 96000 PowerSDR is running under 15% CPU. The ATOM burns EIGHT watts
and
has dual hyperthread cores (shows up as four processors in task
manager).
My intel ATOM computer, case, memory, disk, keyboard/mouse cost me $275.
The motherboard is available for $85 (with processor on it, air cooled)
at
NewEgg. I used it for firewire since there is no firewire. You no
longer
need the LCD display stuff so I hope that is dumped.
The ATOM 330 supports SSE,SSE2, SSE3, SSSE3 so it will run SIMD code
quite
nicely and does so with GnuRadio, SDRMAX, and PowerSDR.
Intel atom mobo/processor bundle: $85

The case has a completely overkill 250w power supply. They must be
expecting you to put a Pentium D MiniITX board in there. ;-). It was
an
excessive thing anyway and done only because it will sit next to the
television in the den.
Already had keyboard and mouse and the firewire card was $12 the last
time I
looked. The (new from Santa) 52" TV is my monitor. Running Ubuntu 8.10
and
Windows XP Pro. I have used it to do GnuRadio, PowerSDR, SDRMAX II,
streamed video's from Netflix, Hulu, Youtube, and more.
This is a cheap enough, high enough performance computer to complete
dedicate it to the task, and never run into a stupid outlook glitch for
PowerSDR. On Ubuntu, it is spiffy to compile GnuRadio pretty quickly
with
make -j4.
I will give some GnuRadio and SDRMaxII numbers later. Phil Covington
has
one so maybe he can give us SDRMax II numbers while I concentrate on
GnuRadio/DttSP.
I will be the first to admit it is not as fast as my QX6700 Ubuntu
machine
or the new I7 extreme machine (dual Fedora, Vista 64 for Nvidia Tesla
programming which requires a GOOD pciE-x16 slot and SLI support and a
$400
Mobo) but it is plenty fast for these dedicated job small CPU tasks
(SDR)
and really cheap. I made no great effort to save money, it is just
cheap
anyway.
I am pushing ahead on the Beagleboard because I think we need to
collectively turn some attention to the embedded low power SoC and I
combine
(along with my embedded programming friends) both ARM and SIMD DSP for
SDR.
Happy New Year,
