Langwell Platform Controller Hub MP20

Meet Moorestown: Intel's Atom Platform For The Next 10 Billion Devices
By

I said earlier that the MP20 chipset was pretty much an empty, downsized shell of its former Poulsbo self, reduced to being a collection of I/O blocks. That’s not exactly true. Yes, Intel builds a USB 2.0 EHCI controller with three ports into the 14 x 14 mm package. There’s also a USB On-the-Go (OTG) host/device port for letting the Moorestown ultramobile connect to other USB devices. Intel’s inclusion of HDMI support is all but overlooked in the Moorestown documentation, but its presence is obviously a key point for those who would like to use their devices as a video player for their TVs.

How about storage? There are four ports for SD/MMC/SDIO devices. More importantly, Langwell supports SLC and MLC NAND “drives” with up to 4KB page sizes and a raw capacity of 64GB. Note that while Langwell supports the CE-ATA spec common for 1-inch Microdrives, there’s no SATA connectivity. Most likely, the feature was considered unnecessary bloat given the part’s target applications. However, Intel does have implementation guidelines for developers that want to employ a third-party USB-to-SATA bridge. The same guidelines also detail how to connect a full-sized keyboard via an I2C interface.

Camera support and image processing also run through the MP20, both for still images and video. Moorestown allows for two cameras—one 5-megapixel and the other VGA (640x480) resolution. The 5MP channel is a dual-lane MIPI interface able to support RGB, YUV, and RAW color schemes, although how this capability gets exposed will be left to developers.

Langwell’s audio engine is more complex than you might expect. Intel uses its in-house Smart Sound Technology (SST), based on a 24-bit DSP, for voice processing and audio codec accelerations. Specifically, Langwell provides hardware-based encode acceleration for AAC-LC and PCM (WAV). On the decoding side, there’s hardware acceleration for AAC-LC, HE-AAC, MP3, PCM, and WMA9. This optimization, along with other elements of Langwell power management, is part of how Intel is able to hit its week-long MP3 playback time target. When the audio engine needs system resources, it generates a power management event, but only the path to memory is enabled. The audio engine refreshes the buffer and the platform quickly returns to its low power state.

While arguably less of a concern for consumers than businesspeople, some will be interested in Langwell’s integration of a security and cryptography engine, which includes the functionality of a Trusted Platform Module (TPM) chip. Intel accelerates AES, DES, 3DES, RSA, and other crypto operations, but the real benefit lies in enabling a secure boot environment, as with vPro systems. This is likely to become increasingly important as mobile devices become a larger target for malware and hijacking. Of course, content providers are keen on the ways in which DRM can be enforced with a security engine, as well.

    Huh, i wonder how this will compete with Bobcat, which supposedly will have 90% of desktop chip performance according to AMD.

    Why isn't this a 32nm product yet? If your concern (which it would be with said devices) is power consumption, shrinking the die can only help...

    Man, and I just got the HTC Incredible... ;) 

    And so the march of technology continues!

    well we can only wait till amd gets their ULV chips out with their on die graphics so we can get a nice comparison.

    Time to market. 45 nm was quicker for development and it accomplished what needed to get done at this time. That's the official answer. Unofficially, sure, we all know 32 nm will help, but this is business for consumers. Right or wrong, you don't play all of your cards right away.

    This is more exciting to me than the release of 6-core processors and the like because these advances produce tangible results for my daily use. Good work Intel!

    Do we really need x86 plaguing phones now? Good God, why didn't they use a more efficient instruction set for this? Compatibility isn't very important with the PC, since all the software will be new anyway.

    I like the Atom, but not in this role. x86 adds inefficiencies that aren't balanced by a need for compatibility in this market.

    I wonder how this would stack up in terms of simple benches when compared to the atoms? Definitly for power this one is a sure winner by far but this will be interesting to see since the line between server, desktop, laptop, netbook, and mobile phone processors are getting blurred

    I'm impressed, and I hope this goes far. Sounds like some awesome performance for a x86 chip that competes to RISC chips.

    I was considering buying a Sony Satio, but now I may rethink it.
    1366x768 multi-touch S-AMOLED, magnesium case, 802.11 b/g/n, 3G/4G, miniDP, miniHDMI, miniDVI, microUSB, 64GB high quality flash memory, 12MP main camera with a 5MP front facing camera, a new turbo boost that pumps cocaine into the chip until it gets too hot when the performance is needed but puts the chip to sleep in idle, and a Linux based OS specifically tailored to the chip. Sounds like something I would pay a lot for. Complete desktop PC replacement. :) 

    Don't disappoint me Intel. I was hoping for 32nm 8 core LGA 1366 chips by now when I originally bought my i7 system, and you already disappointed me.

    Now only if 5GB/month on 3G didn't cost $85/month in my area, never mind the texting/calling plan.

    Intel will for sure put these advancements in their upcoming Desktop CPU families. Low power consumption + high performance anyone?

    I noticed that on the last page of the article there was a reference to "IA Architecture". Is that a typo, or did you mean to be redundant?

    Read the whole article. Read several sections twice. It sure sounds good. Wondering what the monthly fee for service will be in 2015.

    Missed something here that seems fairly critical to the sentence.

    The next checkbox item is battery life. The reality is that we all charge our phones every night. Occasionally, some unforeseen adventure or bout of brain impairment might result in needing to stretch for three or four days, but it’s rare to need a phone’s standby battery time to last for more than 48 hours


    I charge my phone once every week, i would be pretty angry if it didnt hold a charge longer than 48 hours.

    I also only charge my phone once a week, if that. On the same token my phone is now 2 years old and still holds a charge for a week. A lot of people that charge their phone every day also tend to have phones that won't hold a charge longer then a day or two after a year anyway.

    I also don't see the use of all these MIDs. I hardly even take my laptop out because I have a desktop and other then movement there is nothing the laptop can do that I wouldn't rather use my desktop for.

    MIDs might be ok if they didn't cost an extra $30-50 a month to get access to the internet which I'm already paying $30-50 a month for for my general usage. They might start making sense when someone like Qwest starts included DSL and wireless together for a single reasonable monthly fee so I'm not paying twice for the same thing.

    And unless you absolutely have to know the instant you get an email, and can't go more then a few hours without updating your facebook page, I don't see a daily usage for mobile internet. I probably don't think "boy it would be nice if I could check the internet while I'm out" more then once every couple months.

    Articlewill be things like gaming consoles, connected cars, or whatever, we’re still talking about multiple billions of connected handheld devices in use.

    Good luck holding a car in your hands!

    Anyhow, the article seems mighty detailed compared to what we're used to here. Usually only don writes anything this detailed.

    Nice read, though imo the first page looks very much like a bought article.

    Yeah great news I think about what this all means for me! The ultramobile sector growing so fast and becoming more and more preeminent. So much excitement at your hand disposal. I don't know, call me pessimist but when looking at those charts I think the best years for desktop computing started to decline a while ago, sniff. Why, well because I see that the huge market dictates where the real money goes for development. Up to these days the desktop enjoyed most of the investment and this is because the mass market wanted faster computers for everything. And now a regular laptop is powerful enough for 90% of the task most users do and will sell 2 or 3 or more times faster. Soon smaller mobile form factor PCs will dominate and I guess my beloved desktop and workstation parts will start to cost more and be updated less frecuently. I am sitting in front of a workstation all day long and I desire a faster progression for the workstations and no any sigh of slow down.

    Anyway beside the progress in the mobile and ultramobile sector I picture in the not so distant future an ultramobile CPU with memory and graphics and storage system the size of a phone in a modular and stackable design and you will have some very serious and scalable mobile supercomputing power. But will mobile form factor CPUs ever going to surpass the need for a desktop machine? Has the computing revolution started from the bottom up and I just noticed?
