    OK... so before you have another heart attack, I was referring to *shipping* ARM systems. Despite the fact that Calxeda's marketing department called the Atom "vaporware", the Atom actually is shipped in computers today. This ECX-1000 looks nice on paper but is in the development stage for one or two vendors. That's not the same thing as shipping. As for the rest of your rant, I'm not sure what you are trying to prove other than ARM is gradually adding the same features that are expected of even econo-grade server boxes. It's great that these things are being added, but it doesn't mean ARM is going to destroy x86 tomorrow either. As for your "64 bit is already being tested" well so what. 64 bit was being "tested" 13 years ago by both AMD *and* Intel (AMD got to market first but Intel had internal samples for years before the first 64 bit x86 Intel chips were released). If we go by your metric Intel is "testing" next-gen Atoms that are way better than any chip you can get in a smartphone or tablet today, but that doesn't mean Intel is going to take over the smartphone market by next tuesday either.


    Try to be a little less religious about ARM, especially in the Linux world ARM seems to get lots of worship even though their products are vastly more proprietary and locked down than anything Intel or AMD make.

    "Key Features"
    "..Integrated high-performance interfaces such as memory
    controllers with full ECC support
    and I/O subsystems for local SATA
    2.0 ports and PCIe 2.0 support"

    did you blink and miss all these options for ARM you say are missing but in fact are NOT missing at all , in fact some ARM blocks are at the for front of improving speed for everyone even in the x86 space with scalable native PCIe to SSD SOC

    ECC RAM support hardware blocks are everywhere just because YOUR current ARM Mobile phone SOC doesn't have it specified doesn't mean it doesn't exist perhaps you might try the ARM database first before wrongly assuming next time http://infocenter.arm.com/help/index...h09s04s02.html its even got its own entry on the latest High speed ARM AMBA 4 AXI bus OC

    Cortex-R5 Technical Reference Manual Revision: r1p2
    Home > Level Two Interface > AXI slave interface > TCM ECC support

    9.4.2. TCM ECC support


    The TCMs can support ECC, as described in TCM internal error detection and correction. If a write transaction is issued to the AXI slave, the slave interface calculates the required ECC bits to store to the TCM. If the write data width is smaller than the ECC chunk size then a read-modify-write sequence is automatically performed by the AXI slave."



    what else, oh 64bit samples exist and are being worked on right now http://lists.linux-foundation.org/pi...ne/000551.html
    "Will Deacon arm.com The majority of work and discussion around the ARM port is currently focussed on platform code and soc support, as shown by the git traffic generated from the new arm-soc tree.

    However, there are still a few of us working on the core architecturewhich now has support for large physical addresses, virtualisation and other exciting bits and pieces which require work in the core port. There's also a 64-bit architecture on the way...." and when he says on the way he means generally
    availability OC ,not it doesn't exist yet, its already with partners.
    http://lists.linux-foundation.org/pi...ne/000574.html
    ".... PCI breakout session. One of the next major pieces for ARM
    consolidation and DeviceTree support is PCI support. More ARM platformsare appearing with PCIe. I think there's opportunity for consolidation with PowerPC DT PCI code."

    Samsung sell a 512bit memory bus SOC block and chips etc ....you get the idea, Google an ARM block of your choice and it will probably already exist today, and if so it will be in someones commercial SOC and being used right now somewhere you never even considered... will it be available in ARM YOUR Phone next Tuesday for you to use OC not, but it may already be in that SOC and not even used OC so you would never know, for instance.

    information on memory stick is subject to NDAs. E.g. TI always
    omitted MS docs for their chipsets and only provided them
    to MS NDA customers..

      LOL your a funny guy "another heart attack," indeed LOL, although you seem to be full of Fear, Uncertainty, and Doubt, as regards ARM cortex and that's a shame given its been a great week to make lots of cash potential with all the news finally appearing for the masses that don't follow its progress ....

      "Despite the fact that Calxeda's marketing department called the Atom "vaporware""
      a direct URL pointing to these exact words to prove your point if in fact there is one and not simply more FUD and mis interpretation on your part please.

      you do realize that the next atom, is finally at the real tick/tock as it finally moves over to Ivy bridge after a full 5 years of not changing its core, so i agree the ivy bridge SOC may look a lot better than before, we shall see..... as for "religion" and spreading FUD ill leave that to you and the other Luddite puddles
