RE: [Discuss-gnuradio] Intel Atom is NICE.
I did do the install. BEWARE, steps are required. PAY ATTENTION. You need to do a BIOS upgrade to the Dec. 2008 version of the BIOS. I chose to use the ISO to CD ROM and boot from the CD ROM. I tried several times to flash the BIOS and it never succeeded. If I hit F2 after reboot it said that I still had the old BIOS. On reboot each time, it said I had a checksum error. IF ANYONE CAN SHOW ME WHERE IN THE INSTRUCTIONS IT SAYS THIS IS A TWO PASS PROCESS OR WHERE DURING THE COURSE OF DOING THE FLASH IT SAYS THIS IS A TWO STEP PROCESS, I WOULD BE PLEASED TO BE TOLD I AM BLIND. After you do the boot to the ISO CD ROM, and you tell it run, it runs and then reboots. YOU ARE NOT DONE. On the second reboot, it THEN flashes the BIOS and succeeds. I was removing the CD ROM each time after boot so it wouldn't do it again and the checksum error was its BRILLIANT message that it had failed to read the image on the CD. Give me a break! After that was finally accomplished, the Ubuntu 8.10 and F10 CD/DVD respectively started without a kernel panic. Also, the BIOS setup page reveals a new banner page saying Intel 64 Bit processor compatible and not EM64T Processor capable. I have compiled and done make distcheck on Ubuntu 8.10 AMD64 and it works. The GigE works. I just did all of this yesterday and have not had a chance to plugin in my USRP2 yet.

RE: [Discuss-gnuradio] Intel Atom is NICE.
The intel graphics chip set and northbridge are power hungry. I think the idea is optimize code for the 330 and not the peripherals with this inexpensive and easy to use Mobo. The disk drive is hungry as well. The Intel ATOM Z500 family are mobile processors that have the same SIMD registers, support LCD, good GigE support, and the potential wart (POTENTIAL) is the 100 or 133 MHz FSB. http://www.axiomtek.com.tw/Products/ViewProduct.asp?view=680#3 The Virginia Tech Mobile (SDR/CR) groups are looking at these (largest SDR/CR department in the world I think). I think we want to optimize SIMD code and see what we can get running on these prepackaged, easy to get up and running systems as well as the SoC parts such as that family of TI OMAP parts carried on the Beagleboard. One does NOT need to spend thousands of dollars on an SDR computer for most operations. That is a convenient excuse for me to justify my computer budget for development and get high end things to play with (so I can kill aliens from another galaxy or FSU laboratory with impressive graphics in my spare time). But most people need to really justify the need for the high end computer in my mind and they cannot. That is my point in all of this. SDR wants to be on consumer/commodity level processors and SoC to be in everyone's coffee budget and taken for granted in the ideal world in my book. There seems to be little gained by optimizing this for Quad core extreme processors with massive GPU's sitting on them, tons of expensive high speed memory, and the world's fastest drives and costing well upwards of $1000 US. Lightweight, easy to distribute, with browser level GUI's and distributed everything on inexpensive processors and we rule the world.

Pushing key elements to other reconfigurable processors, e.g. the USRP2 FPGA, will greatly ease the burden of the GPP.

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?

Bob Hello, I bought the earlier version of the motherboard with just the 10/100 ethernet. I put it in a MI-100 case and it is a nice little system. I have not gotten a chance to use it with GNURadio much so I have not commented about it on the list. I am thinking of using it as a car computer. However, I have tried it under Windows XP with my AutumnWave OnAir GT USB HDTV tuner. I understand this tuner uses the computer to decode the HDTV signal. On my older Thinkpad z60t (1.73 GHz Pentium M) the HDTV decode takes about 80% CPU and there are ocassional gliches. I was not happy. With the Intel Atom (1.60 GHz), the HDTV decode takes about 40% CPU and decode is excellent. I suspect the hyperthreading feature of the CPU is causing the improved decoding. I recently bought a Acer Aspire One (Intel Atom and 120GB HD) on sale. I plan to put Linux on it and see how it works with GNURadio and the USRP. I feel the advantage of the Intel Atom is reasonable performance in a small package. The Atom-based netbook may be useful for dealing with ham and conventional narrow-bandwidth signals in a portable/mobile SDR package. The 945 chipset is power hungry but I heard there is another chipset for the Atom in the works. Hopefully the new chipset will allow using the GPU for SDR work. 73 Eric ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
[Discuss-gnuradio] 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 http://www.newegg.com/Product/Product.aspx?Item=N82E16813121359 case: $56 http://www.newegg.com/Product/Product.aspx?Item=N82E16811154084 memory: $21 http://www.newegg.com/Product/Product.aspx?Item=N82E16820134192 drive: $79 http://www.newegg.com/Product/Product.aspx?Item=N82E16822136320 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.

Re: [Discuss-gnuradio] Intel Atom is NICE.

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). Unfortunately the 945 chipset eats ~20W - god knows why Intel lumbered the Atom with it :( Toms Hardware (and others) did a test of the Atom vs an underclocked Athlon and the later won most of the tests http://www.tomshardware.com/reviews/Atom-Athlon-Efficient,1997-1.html I think the Atom combo is cheaper and smaller though :) -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au The nice thing about standards is that there are so many of them to choose from. -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C signature.asc Description: This is a digitally signed message part. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
