Core Values: The silicon behind Android
Core Values is our new monthly column from Anand Shimpi, Editor-in-chief of AnandTech. With over a decade of experience poring over the latest in chip developments, he's here to explain how things work and why our tech is the way it is. Remember this chart? It's interesting for a number of reasons, but I want to highlight that all present day Android phones use virtually the same Qualcomm application processor, all based on a sluggish 528MHz ARM11 core. Blech. I've got nothing against Qualcomm, but a big reason most Android phones feel slow is because they're running on slow hardware. The ARM11 core was first announced in 2003. It's old and creaky, and it's used so frequently because it's cheap. But the basic rules of chip design mean that things are about to change fast.
Sharp's PC-Z1 NetWalker takes the inevitable unboxing journey
Sharp's PC-Z1 NetWalker conjured up all sorts of love and hate-filled emotions when we toyed with it earlier this month, but for fans of unorthodox handhelds, minor details like a wonky optical pad and frail keys aren't apt to put a damper on the excitement found in this moment. The cool kids over at Pocketables were able to procure a unit over the weekend from Japan (right on cue, might we add), and predictably, they've broken out the camera in order to let you relive the unboxing experience and see it side-by-side with a UMID mbook M1. The read link folks, that's where it's at.
Archos Android Phone Tablet introduced on video
We'd heard that Archos had teased an Android-based phone when it launched the new Archos 5 Internet Tablet, and now we have video proof. We don't speak French well enough to translate what's being said here (or, really, translate anything other than "le singe conduit l'autobus") but that spec sheet isn't too hard to figure out: we're looking at a 1GHz ARM Cortex processor under a 4.3-inch 854 x 480 screen in 10mm thin titanium casing with what looks like a front-facing camera. Yeah, not too shabby at all, especially considering Archos has that interesting media layer running on top of Android already -- let's hope we find out even more soon. Video after the break.[Thanks, Fernando]
ARM's Cortex-A9 beats Atom N270: too bad it's not 2008
ARM's doing some chest thumping today by revealing a 2GHz clock speed on its dual-core Cortex-A9 processor. The move is meant to remind manufacturers that ARM can scale beyond its traditional smartphone strong-hold and into netbook territories currently dominated by Intel. ARM's even handing out benchmarks showing the Cortex A9 out performing Intel's single-core 1.6GHz Atom N270 -- a processor launched back in 2008. Of course, Intel already ships a dual-core Atom 330 processor with its low-power Pineview processor set to launch on the near-horizon. It's also worth remembering that Windows 7 won't run on ARM so future Cortex A9 smartbooks will have to settle for Windows CE, Android, or perhaps, Google's Chrome OS if you ask politely. ARM is licensing its Cortex A9 speed- and power-optimized technology today with delivery in the fourth quarter of 2009. [Via PC World, thanks Ian]
Tetris players found to have greater brain efficiency, thicker cortex and better hair
You just knew all that Tetris playing you did as a kid yesterday was good for you, huh? A new study published by the big thinkers at Mind Research Network has found that "practicing Tetris" can actually improve brain efficiency and lead to a thicker cortex in other areas of the tabula rasa. In short, the study was done in order to show that the brain can change with stimulation, and that "a challenging visuospatial task has an impact on the structure of the cortex." Of course, this is far from the first published report to use the quarter century-old title as its testing tool, but it's certainly one of the best for getting your mum and pop to believe gaming really is good for the gord. Hit up the read links below for all the details -- you know they'll be firing off questions when you hit 'em with this.[Image courtesy of BumpyBrains]Read - Tetris study [PDF]Read - Press release
Sharp's 5-inch PC-Z1 NetWalker honors Zaurus legacy with touchscreen Ubuntu
Fanboys have been running Ubuntu on Sharp's deceased Zaurus lineup of PDAs for years. Now Sharp makes it official with the launch of this 5-inch, 1024 x600 TFT LCD touchscreen NetWalker smartbook, aka the PC-Z1. It's not a Zaurus per se, but the compact 161.4 x 108.7 x 19.7 ~ 24.8mm / 409g device certainly resurrects its ghost. Underpinning the device is an 800MHz Freescale i.MX515 CPU built around the ARM Cortex-A8 architecture, 512MB of memory, 4GB of on-board flash storage (with microSDHC expansion for another 16GB), 802.11b/g WiFi, 2x USB, and QWERTY keyboard going 68 percent of full-size. Sorry, no 3G data. The PC-Z1 features a 3-second quick launch, non-removable 10-hour battery, and is purposely positioned by Sharp as a taint -- it ain't quite a smartphone and 't ain't quite a laptop. Good luck with that Sharp. The device is expected to hit Japan on September 25th for ¥44,800. That's about $479 whenever it might come Stateside. It's worth noting that the current US ban on the import of BGA-packaged products like Freescale's i.MX processors should not affect the import of the PC-Z1 as Akihabara News contends. As we understand it, that ban affects the import of the chips, not the systems using them and assembled elsewhere. Otherwise, Amazon wouldn't be selling its Kindle, dig?[Via Akihabara News and Engadget Japanese]Read [warning: Japanese PDF]
ARM promises dual-core Cortex A9-based smartphones next year
The world's two most visually engaging smartphones -- the iPhone and the Pre -- share very similar cores based on ARM's Cortex A8 architecture, and with the newer, more advanced Cortex A9 in the pipeline, you can't help but let your mind wander a bit as you envision what twice as much computational power could bring to a handset. The A9 employs more advanced instruction pipelining than its predecessor, but the biggest news has to be the fact that it can pack two or more cores -- and ARM fully expects dual-core A9-based phones to hit in 2010. Of course, power consumption is the biggest constraint when it comes to this category of device, and while the company says that peak drain will exceed that on today's crop of devices, average consumption will actually drop thanks largely to a move from 65nm to 45nm manufacturing processes. Add in 1080p video promised by TI's next-gen OMAP4 silicon wrapped around an A9 core, and you've basically got a home theater in your pocket that's ready to rock for a few hours on a charge. That and Snoop Dogg, of course.
Freescale netbook and Android-powered smartbook debut
We knew good and well that Freescale wouldn't let Qualcomm go and have all the fun with these newfangled smartbooks, and already we're seeing a few new devices powered by Freescale-branded semiconductors. In the video posted just after the break, the company's own Steve Sperle sat down to talk about a new Pegatron netbook (which handles 720p video playback with ease) as well as an Inventec "smartbook" which is just marginally larger than your average smartphone. In fact, we're rather impressed with the layout: a larger-than-average 4-inch display, a slideout QWERTY keyboard and Google's Android OS. Unfortunately, Mr. Sperle would only stick close to the "later this year" launch time frame that we'd already heard about, but so long as these smartbooks end up looking like overpowered smartphones, you can certainly consider our interest piqued.
ARM-based netbooks primed to invade Computex?
Steppin' out in the world, are we ARM? Shortly after hearing that OLPC was eying the brand for processors in the XO-2, Digitimes is now reporting that ARM-based platform makers including Qualcomm and Freescale are looking to unveil netbooks at this year's Computex trade show in Taipei. Granted, none of this has been confirmed just yet, but we're hearing that a model with Freescale's i.MX51 CPU (the ARM Cortex A8) and a version with Qualcomm's Snapdragon CPU (to be manufactured by Wistron) will be on hand. Not shockingly, in the same breath we're told that NVIDIA Tegra-based systems will appear "at a later time." So, is Computex the show where Intel finally takes a little heat in the netbook market? And no, VIA didn't (and doesn't) count.
Cortex-M0: smallest, lowest power ARM processor available
If you love superlatives, you'll love ARM's new Cortex-M0. Hailed as the smallest, lowest power and most energy-efficient ARM processor available, this chip reportedly enables MCU developers to "achieve 32-bit performance at an 8-bit price point." The company asserts that this processor can consume as little as 85 microwatts/MHz (0.085 milliwatts) in an area of under 12K gates when using the ARM 180ULL cell library, and while that's probably over most of your heads, let's just say that this thing is ripe for use in medical devices, e-metering, lighting, smart control, gaming accessories and the like. Those looking to get this into their next widget should be thrilled to know that it's available today for licensing, though you'll have to phone up someone in the know to talk dollars and cents.
TI's OMAP 4 bringing 1080p support to smartphones and MIDs
Right around this time last year, Texas Instruments was busy showing off its OMAP 3 platform, which enabled 720p playback from a mobile phone. At this year's MWC, we've got a real live handset recording 720p, and TI upping the ante once more with a chip that handles 1080p. For those still with us after being blasted with resolutions, the predictably titled OMAP 4 aims to bring 1080p support, 20 megapixel imaging and "approximately a week of audio play time" to mobiles and MIDs that house it. Granted, TI also calls this stuff "future-proof," so don't believe it's totally incapable of uttering some pretty outlandish stuff. At the heart of the platform is a dual-core ARM Cortex A9 chip, a programmable multimedia engine based on TI's C64x DSP and a POWERVR SGX540 graphics engine. We're told that it'll play nice with Linux variants such as Android and LiMo, Symbian and Windows Mobile, though it'll have to be mighty impressive to outgun NVIDIA's Tegra. Battle on, we say.[Via Linux Devices]
ARM debuts Sparrow multicore netbook processor
We've had our eyes peeled for ARM Cortex-based netbook news, and now among the action this week at MWC '09 we're getting our first look at Sparrow, a Cortex A9 processor aimed squarely at netbook manufacturers. This is a multi-core update to the Cortex A8 (processor of choice for the Palm Pre and Pandora), and it's been speculated that this could be the processor for the next generation iPhone, with "at least triple the computing power of the ARM11 processors found in the [current] iPhone and T-Mobile G1." Toshiba, Pegatron and Wistron are all said to be showing demos of their ARM-powered netbooks at the conference this year, with a company spokesman saying that Ubuntu for ARM will go public in April, with Sparrow phones coming to market sometime in 2010. Additionally, companies like Adobe, On2, and Symbian are said to be "tuning their apps to run on the latest cores from ARM" as we speak.[Via Gadget Mix, Mac Rumors]
Texas Instruments demos first 720p playback from a mobile phone
Texas Instruments demonstrated its first processor to enable high definition (720p) playback on mobile phones yesterday at 3GSM World Congress. The OMAP3430, first announced last year, is the first in TI's series of OMAP 3 processors and also first to include support for the OpenGL ES 2.0 graphics standard for 3D acceleration. The 3430 gets the muscle to move your HD files and 3D gaming from its embedded ARM Cortex-A8 processor, but from the specs it seems that the video portion is only currently supporting up to 1024 x 768 (XGA) output via composite or S-video connections. Still, with this power available, sometime in the future your common cellphone will be playing back HD on the go or outputting video to a big screen HDTV. We previously expected to see handsets based on the technology this year, but while TI is shipping samples of the processors now, don't expect your HD-capable cell to hit stores until early 2008.
