ARM and eyeSight optimize gesture control for mobile processors
Hands-free gesture control is no longer a novelty in the mobile space, but the required processing power limits what's currently possible. More sophisticated input may be close at hand, however, as eyeSight has just teamed up with ARM to optimize its gesture control for chips using Mali-T600 series graphics. By relying on the T600's general-purpose computing engine, eyeSight's software can now track 3D movement, facial expressions and finger gestures without a huge performance hit. While companies will have to build supporting apps and devices before we see eyeSight's technology in use, it could lead to Kinect-like control of phones and smart TVs using relatively ordinary silicon.
Microsoft sees future for ARM-based tablets, but maybe not Windows RT
The rest of the industry may have turned its back on Windows RT, but it looks as if Microsoft isn't prepared to ditch the Windows-on-ARM dream just yet. During an analyst call, Terry Myerson, Microsoft's recently crowned software chief, seemed to describe RT as a first attempt, which will be followed up by further devices in the future: "Windows RT was our first ARM tablet(sic). And as phones extend into tablets, expect us to see many more ARM tablets, Windows ARM tablets in the future." Myerson's choice of words, and in particular his reference to phones that "extend into tablets," suggests that Microsoft could be looking to bridge the divide between its smartphone and tablet divisions, and perhaps give Windows Phone a much more prominent role than the much-maligned Windows RT. Indeed, using Windows Phone as a tablet OS, or merging WP and RT, would help Microsoft to unify its various platforms and apps -- something it has talked about in the past and that is actually a key focus of Myserson's work: "... we really should have one silicon interface for all of our devices. We should have one set of developer APIs on all of our devices. And all of the apps we bring to end users should be available on all of our devices." So, who knows, perhaps Windows Phone and RT have a common future? In which case, the idea of Nokia taking charge of this unified drive -- building phones and tablets on the same platform -- would make a lot of sense.
Exynos 5 Octa demos 8 cores working at once and other feats of CPU strength (video)
Just in case yesterday's news that Samsung is ready to enable new features on its Exynos 5 Octa chips wasn't clear, ARM has published a few demo videos to show what it can do. All three are embedded after the break, and the first one highlights how the Exynos 5 Octa 5420 can activate some or all of its 8 cores to maximize responsiveness while launching and using Quickoffice. As you can see above in the screenshot, all eight cores are activated while launching the app, then unused ones switch off for more efficiency. Another video shows how it runs Angry Birds Rio on just the four Cortex-A7 "LITTLE" side of the CPU, rarely activating any of their more power-hungry A15 friends. The last demo video shows how its Mali-T628 GPU activates to process images faster and more efficiently than the CPU alone can.
AMD's 2014 embedded roadmap includes dedicated graphics, gaming-friendly CPU
AMD has long signaled that embedded chips will play a major role in its future, and it's backing up that claim by providing a glance at its 2014 roadmap. The highlight is Bald Eagle, a 35-watt x86 processor designed for demanding tasks like gaming; it should include up to four Steamroller cores, and it will optionally sport on-chip Graphics Core Next video. Devices that need even more visual power will use Adelaar, a dedicated graphics chipset that includes both GCN and 2GB of built-in memory. It's reportedly fast enough to be useful for PC video cards, not just the usual set-top boxes and smart TVs. Two system-on-chip designs are also joining AMD's lineup. Hierofalcon is built with data centers in mind, and carries up to eight ARM Cortex-A57 cores; Steppe Eagle, meanwhile, is a combination of upgraded Jaguar x86 cores and GCN that should speed up AMD's low-power G-series processors. With the exception of Hierofalcon, all of the new embedded chips should be available in the first half of next year. AMD hasn't named any early customers, but its embedded silicon tends to reach products that you'd recognize. Check out the roadmap after the break.
Samsung's Exynos 5 Octa CPUs will be able to use all eight cores at once in Q4
We'll have to change our terminology for Samsung's Exynos 5 Octa mobile chips now. We've been calling them "not-quite" eight core CPUs since they can't actually use all eight at once, but the company's new Heterogeneous Multi-Processing solution is going to change that. Once it's available in Q4 it will let devices access both sides of the big.LITTLE ARM configuration simultaneously, which it claims will increase both performance and efficiency. While software threads with high priority use the "big" A15 core, lower priority tasks can run on the "small" A7 without needing to switch back and forth. Samsung isn't the only one running this setup however, as MediaTek announced an implementation for its MT8135 back in July. There are more details included in the press release (after the break) but we're not seeing any confirmation if this will ever be enabled on existing / announced devices like some flavors of the Galaxy S 4 or the Meizu MX3. Either way, the folks at Qualcomm might want to put together another video.
Switched On: Windows ReTreat
Each week Ross Rubin contributes Switched On, a column about consumer technology. Today's hottest and best-selling tablets and smartphones have one thing in common: they are powered by ARM processors. Offered in such variations as NVIDIA's Tegra, Qualcomm's Snapdragon, Samsung's Exynos and Apple's A6, ARM processors dominate the leading edge of mobile products. At LG's recent announcement of its clever and well-appointed G2 smartphone, much was made of it being the first globally launched phone to include Qualcomm's Snapdragon 800; Android, in contrast, wasn't mentioned once. And the long reach of ARM extends far beyond the bleeding edge. The Hisense Sero 7 Pro -- recently cut to $129 just a few weeks after its launch -- has a Tegra 3 processor while ARM chips from Rockchip and MediaTek power Android tablets at even humbler price points. For years, Intel has promised it would be competitive with ARM in terms of performance per watt (if not in price). It has made great strides both in its smartphone-focused Atom chips and its performance-oriented Core chips (including Haswell, the CPU behind the MacBook Air's huge gains in battery life), but those in the ARM camp have kept their processors' competitive heat up while keeping their generated heat down.
Samsung reportedly looking to engineer new ARM-compatible Exynos processor
It's a material world, and Samsung's just living in it. And, evidently, it's tired of doing things in the same manner it has been. According to a report from ETNews, the aforesaid company is looking to produce an Exynos processor using a "redesigned ARM core platform" that'll be whipped up in Samsung's Austin, Texas-based R&D facility. If the plans materialize, it'll mark the first time that Samsung has engineered an Exynos chip "based on its own architecture platform by redesigning the ARM cores." For those unaware, Qualcomm and Apple are amongst the precious few that have concocted their own platforms after inking an architecture licensing deal with ARM, and it sounds as if Sammy's tired of being on the outside looking in. The report also states that development is expected "to be completed early next year," and you can bet that future Galaxy and Note products will be the first to benefit.
ARM sees more double-digit growth in Q2 2013, takes big hit from patent litigation
This UK chip designer is accustomed to steep growth in demand for its Cortex mobile processors, and although we've seen hints that it faces new challenges ahead, for now it's mostly all gravy. Revenue in Q2 2013 soared 26 percent year-over-year to £171.2 million ($264.3 million), while profit before tax was up 30 percent £86.6 million (in "normalised" terms). Mobile devices remain the largest market for the company, but embedded devices (including wearables, Raspberry Pi and printers) is the fastest growing segment, expanding by 25 percent in the last year. The future continues to look rosy for ARM, with new Samsung Exynos 5 chipsets arriving based on ARM's Cortex-A15 and Cortex-A7 cores in big.LITTLE configurations. The only hint of negativity in the earnings report was a huge expense of £41.8 million incurred by a patent attack from an unnamed "third party", which was probably MIPS (see More Coverage), and which contributed to a much lower IFRS profit of £15 million -- although this represents ARM's contribution to a "full and final settlement," which presumably means it's a one-off thing.
Samsung puts the new Exynos 5 Octa 5420 SoC up against a Nexus 10 at SIGGRAPH 2013 (hands-on video)
In case you were already snoozin' when Samsung made its announcement late yesterday, the company is here at SIGGRAPH 2013 eager to show off the muscle behind its new chip. Before the exhibitions start officially, we had a chance to nab a look at a reference tablet running the Exynos 5 Octa 5420 SoC alongside ARM's Mali T-628 silicon packing six cores. For comparison purposes, the prototype unit was matched against a Nexus 10 tablet and its 1.7GHz Exynos 5 Dual 5250. Our first impression? The 5420 ran GLBenchmark's 2.7.0 T-Rex on-screen test noticeably (read: a lot) smoother than the Nexus 10 and the final scores confirmed the performance boost that we previously reported. We also had a look at both the Unreal Engine's Citadel (up to 45fps at times) and Unity Chase on the test device with both further demonstrating silky smooth transitions and brisk graphic renders. There's no word on when the chip will make it into your next mobile device, but it is scheduled to go into production next month. For a quick look at the two tablets side by side, we'll refer you to the video embedded just beyond the break. %Gallery-194455%
New Exynos 5 Octa: 20 percent more CPU power, over twice the 3D graphics oomph
Samsung couldn't help itself last week when it teased a new Exynos 5 Octa system on a chip, and now it's dishing out the full details. The fresh 5420 variant of the SoC is based on Mali-T628 MP6 silicon, packs a quartet of ARM Cortex-A15 cores running at 1.8GHz and four 1.3GHz Cortex-A7s in an ARM big.LITTLE configuration. Seoul claims that the package packs 20 percent more CPU processing punch, and has two times greater 3D graphics power than its predecessor. Dual-channel LPDDR3 at 933MHz gives the processor a screaming memory bandwidth of 14.9 GBps, which lends it full HD WiFi display support. Baked inside is an image compression solution that makes for energy efficient multimedia loading, and squeezes out more hours of use with high-res displays. There's no word on which devices might use the new SoCs, but the chips are already being sampled by Samsung's customers, and mass-production is slated for August.
Samsung: new Exynos 5 Octa SoC coming next week
Samsung's current ARM superchip, the Exynos 5 Octa, was revealed at CES and has just started making its way into handsets, but the company claims it's already got a new and improved version ready to roll. Today, the company's SamsungExynos Twitter account revealed that a "more powerful, enhanced" Octa will make its debut next week. What, exactly, that means remains to be seen, but we'll be bringing you that info as soon as Samsung dishes it out. Stay tuned.
Meet Utilite, a $99 quad-core ARM-based PC running Ubuntu
That box you see above? It's a quad-core ARM-based PC running Ubuntu called Utilite. The desktop system, made by Compulab, will be available next month starting at $99. While there are plenty of Android dongles built on ARM SoCs out there, few (if any) can truly offer a PC-like experience. The company -- best known for its Trim Slice, Fit-PC and MintBox products -- wants to change this. Utilite packs a single-, dual- or quad-core Freescale i.MX6 Cortex-A9 MPCore processor (up to 1.2 GHz), up to 4GB of DDR3 RAM (1066MHz), an mSATA SSD (up to 512GB), WiFi b/g/n, Bluetooth 3.0, HDMI and DVI-D outputs, two Gigabit Ethernet sockets, four USB 2.0 ports, one micro-USB OTG connector, audio jacks (analog and S/PDIF), a micro-SD XD slot and two ultra-mini RS232 interfaces -- phew! Rounding things up is support for OpenGL ES, OpenVG and OpenCL EP plus multi-stream 1080p H.264 on-chip decoding. All this fits in a chassis mesuring just 5.3 x 3.9 x 0.8 inches (135 x 100 x 21mm) and only consumes 3-8W using a 10-16V supply (unregulated). Those are impressive specs for the price, and the system sure looks positioned to compete favorably with some of the x86 boxes out there.
MediaTek to launch true 8-core, 2GHz MT6592 chipset in November?
Samsung may already have its 8-core Exynos 5 Octa offering, but the original "big.LITTLE" implementation means only up to four cores work together at any time -- either the Cortex-A15 quartet or its lesser Cortex-A7 counterpart. In other words, we'd rather rename the chipset range to something like "Exynos 5 Quad Dual." But according to recent intel coming from Taipei and Shenzhen, it looks like Taiwan's MediaTek is well on its way to ship a true 8-core mobile chipset in Q4 this year.
Linux kernel 3.10 arrives with ARM big.LITTLE support
Thanks to Linus Torvalds' figurative stroke of the pen, the Linux kernel 3.10 is now final -- paving the way for its inclusion in a bevy of Linux distributions, and even offshoots such as Android and Chrome OS. The fresh kernel brings a good number of changes, such as timerless multitasking, a new caching implementation and support for the ARM big.LITTLE architecture. In simplistic terms, the new multitasking method should help improve performance and latency by firing the system timer only once per second -- rather than 1,000 times -- when tasks are running. Meanwhile, users with both traditional hard drives and SSDs will find performance benefits from bcache, which brings writeback caching and a filesystem agnostic approach to leveraging the SSD for caching operations. Also of significance, Linux kernel 3.10 enhances ARM support by including the big.LITTLE architecture, which combines multiple cores of different types -- commonly the Cortex-A7 and Cortex-A15 -- that focus on either power savings or performance. The full list of improvements is rather lengthy, but if you feel like nerding out with the changelog, just grab a caffeinated beverage and get to it.
Imagination Tech reveals Warrior CPU core to fight (uphill) battle against ARM
This news isn't remotely surprising, given Imagination Tech's recent acquisition of CPU designer MIPS, but reporting it still gives us a little flutter of excitement. And for good reason: Imagination has just revealed that its first MIPS-based CPU core, which should be able to run Android, will be introduced by the end of this year, and that it'll go by the totally appropriate codename of Warrior (or, less dramatically, "MIPS Series5"). The core's first battle will be to prove that the MIPS architecture really can be a competitive alternative to ARM (which uses a similar low-power RISC architecture) and that Imagination didn't just blow $100 million on hot air. Speaking of which, the attached press release comes with plenty of bold claims, including a statement that the 32-bit and 64-bit versions of Warrior will offer "best-in-class performance and efficiency," and a promise that Imagination "will change the landscape for CPU IP." We have no idea how all of this is going to play out, but we fully intend to be ringside when it does.
AMD details first ARM-based server chip: up to 16 helpings of Cortex-A57 clocked at 2GHz
It's hardly a secret that AMD has stepped out of its x86 comfort zone to develop an ARM-based server chip, but now we know a little more about it. Going by the name of "Seattle" and scheduled for launch in the second half of next year, it'll be built around ARM's 64-bit Cortex-A57 in either 8- or 16-core configurations, which will likely be clocked at a minimum of 2GHz. In an apparent acknowledgement of ARM's superiority at low wattages, we're told that this design has the potential to deliver 4x the performance of AMD's current Opteron X processors, with improved compute-per-watt. There's a clear limit to AMD's reliance on ARM, however, as it'll use Seattle to up against Intel's little Atoms, but will continue to sell its own x86 designs for higher-power applications. Meanwhile, we're still waiting on something more interesting from this union, which might be an ARM CPU paired with a Radeon HD graphics processor in some sort of mobile-class SoC. Guess we'll just have to be patient.
ARM unveils Cortex-A12 CPU and Mali-T622 GPU in expectation of a mid-range boom
Few trend-spotters would disagree with the following prediction from ARM, but it's worth laying it out anyway: Of the 300 million mobile devices sold in 2010, the majority cost over $400. Within the next two years, however, these "crazy money" products (as a spokesperson described them) may represent just 25 percent of the total mobile market -- still huge in absolute terms, since almost two billion phones and tablets are forecast to be sold in 2015, but a distinct minority relative to entry-level and mid-range options. In an effort to convert these expectations into an even taller heap of gold, ARM has just announced a new mid-range core, the Cortex-A12, which is designed to replace the aging Cortex-A9 while offering a 40 percent boost in performance. This gain will likely come with the added advantage of better battery life, since the Cortex-A12 will initially be fabricated at 28nm instead of 40nm, and will be offered to manufacturers alongside a new Mali GPU (the Mali-T622) and video engine (Mali-V500) that promise further power savings of their own. The Cortex-A12 will also support big.LITTLE configurations, allowing it to be installed alongside Cortex-A7 cores that will take over for low-effort tasks in order make further power savings. Big.LITTLE hasn't really blown us away so far, at least not on the Octa-core Galaxy S 4, but its wrinkles may well have been ironed out by mid 2014, which is when the Cortex-A12 is due to land. Check out the PR for more technical details on each component. Richard Lai contributed to this report. %Gallery-190050%
MediaTek unveils quad-core MT8125 processor for budget tablets
MediaTek told us to only expect its tablet-focused SoC in the summer, but it's clearly something of a keener: we're already looking at the part today. The new MT8125 builds on the familiar formula of a quad-core Cortex-A7 processor and PowerVR Series5XT graphics, with most of the improvement coming from a higher 1.5GHz clock speed. That extra grunt helps the chip handle up to a 1,920 x 1,200 display on top of earlier support for 13MP cameras and 1080p videos. Focusing on tablets gives MediaTek some freedom in configurations, too -- it can offer the SoC with basic EDGE cellular data, full HSPA+ or WiFi alone. Customers won't have to wait long to try the MT8125 when tablets like Lenovo's IdeaTab S6000 series should be using it now, although there's no word on how much of that hardware will reach the US.
Columbia University's low-cost robotic arm is controlled by facial muscles, we go face-on (video)
We've seen Emotiv's Epoc headset control cars and trapeze acts, but now a small posse of students at Columbia University is teaching it how to control a robotic arm. The appendage, aptly named ARM for Assistive Robotic Manipulator, was envisioned as a wheelchair attachment to help the disabled. According to the team, the goal was to keep costs in the neighborhood of $5,000 since insurance outfits Medicare and Medicaid won't foot a bill for assistive tech that's much more than $10,000. To keep costs low, the crew built the limb from laser cut wood, and managed to keep the final price tag at $3,200. Since picking up EEG signals and interpreting them accurately can be tricky, the group says it settled on monitoring EMG waves, which are triggered by muscle movements, for additional reliability. Lifting your eyebrows makes the device open its grip, clenching your teeth shuts it and moving your lips to the left and right twists the claw, while other motions are currently handled by using a PlayStation 2 controller. In the lab, the contraption has seven degrees of freedom, but it was reduced to five when we took it for a spin. It was hit or miss when this editor put the headgear on, between making sure facial gestures were spot on and the equipment's attempts to pick up clear signals.%Gallery-187534%
Spark Core board adds WiFi to almost everything, takes input from anywhere (video)
Spark Devices wants the inclusion of WiFi in devices to be a matter of when, not if -- and if its new Spark Core gets to market as planned, tinkerers might never have a moment of doubt. The tiny board combines an Arduino-compatible ARM Cortex-M3 platform with a TI CC3000 WiFi chip that not only simplifies getting online, but could save the DIY crowd from having to touch projects afterward. Owners can flash the firmware with new code over WiFi, for a start. A free Spark Cloud service also allows for custom apps that interface with the Core through seemingly anything with an internet connection: if you want to reconfigure a homebrew security camera from your phone, you can. While Spark Devices is relying on crowdfunding to fuel its connected strategy, the company is comfortably past its $10,000 goal and should deliver both the Spark Core ($39) and optional shields to new contributors around September. [Thanks, Greg]
