Google on Friday revealed that Marvell Technology Group and Nvidia Corp. are working on application processor modules for upcoming Ara smartphones. Previously a number of companies have publicly expressed support of the project Ara, but no one has revealed any particular plans. The disclosure from Google is generally the first announcement of particular Ara-compatible products.

Marvell and Nvidia are designing application processor (AP) modules featuring the first-generation Toshiba UniPro bridge ASICs for project Ara Spiral 2 prototype smartphones. The modules feature Marvell Armada PXA1928 (four ARM Cortex-A53 cores, Vivante GC5000 graphics, 2G/3G/4G communications) and Nvidia Tegra K1 (four ARM Cortex-A15/two Nvidia Denver cores, GeForce graphics based on Kepler architecture with 72 stream processors, no baseband capabilities) system-on-chips, but it is unclear what else, apart from APs and bridges, they include.

While it is nice to see the first AP modules for Google’s project Ara modular smartphones, it should be noted that for now they are only compatible with the Spiral 2 prototypes of the platform. The Spiral 3 prototypes, which are due in Spring, 2015, will reportedly use Toshiba’s second generation UniPro switch and bridge ASICs with a contactless M-PHY data transfer capability (using inductive AC-coupling). It is unclear whether the Spiral 3 prototypes will be compatible with the Spiral 2 hardware.

Google plans to start sales of the first project Ara smartphones next year. It is unknown whether commercial Ara handsets will be based on the Spiral 2 or the contactless Sprial 3 prototype chassis.

KitGuru Says: As smartphones, tablets, notebooks, wearables and other mobile devices gain integrated functionality in a bid to become thinner, smaller and more power efficient at the cost of modularity, Google’s project Ara goes in the opposite direction. Google has publicly acknowledged that the Ara smartphones will be thicker, more power hungry and heavier than off-the-shelf handsets. Will such devices become popular? Or will they remain toys for geeks? Only time will tell.

Acer Group has announced the world’s first Chromebook – a notebook running Google’s Chrome OS – powered by Nvidia Corp.’s Tegra K1 system-on-chip. The laptop offers everything that the Chrome OS has to offer in addition to a high-performance application processor from Nvidia and up to 13 hours of battery life.

The Acer Chromebook 13 is based on quad-core Nvidia Tegra K1 SoCs with ARM Cortex-A15 general-purpose cores and Kepler-based GeForce graphics processor with 192 stream processors. The systems come with 13.3” anti-glare displays, LPDDR3 RAM, solid-state storage, 802.11ac Wi-Fi with 2*2 MIMO antenna, USB 3.0, 720p webcam, stereo speakers, a microphone and so on.

The new Chromebooks from Acer will exist in three versions:

  • The Acer Chromebook 13 CB5-311-T9B0 – 1920*1080 full HD display, 2GB of memory and a 16GB NAND flash storage. It carries $299.99 price-tag in the U.S. (€223, £177 without taxes);
  • The Acer Chromebook 13 CB5-311-T1UU – 1920*1080 full HD display, 4GB of memory and a 32GB NAND flash storage. It is priced at $379.99 in the U.S. (€283, £225 without taxes);
  • The Acer Chromebook 13 CB5-311-T7NN – 1366*768 full HD display, 2GB of memory and a 16GB NAND flash storage. The recommended price is $279.99 (€208, £165 without taxes) in the U.S.

The design of Acer Chromebook 13 resembles that of Apple’s MacBook Air, whereas the weight does not exceed 1.5 kilograms. Acer claims that its Chromebooks have battery life between 11 and 13 hours.

The main problem of Chromebooks is that they require Internet connection to offer users advanced functionality. Since the quality of Internet connections varies, the majority of people just play it safe and get familiar Windows-based laptops. Still, the situation is gradually improving and there are programs for the Chrome OS that can work offline as well.

Gartner predicts that sales of Chromebooks will only reach 5.2 million units this year, hence, Acer will barely sell a lot of its Chromebook 13 devices. Nonetheless, it is remarkable that the company can provide basic computing functionality and premium visual quality using a mobile application processor.

The Acer Chromebook 13 starts shipping this month and will be available in European, North American and Asia Pacific markets.

KitGuru Says: While the prospects of Chromebooks are not truly good, it should be noted that prospects of low-cost PCs running SoCs akin to Nvidia’s Tegra K1 are pretty nice. Next-generation Windows 9 “Threshold” is expected to support both ARM and x86 microprocessors (since it will be designed for smartphones, tablets and PCs), which will automatically open the door for Tegra K1 to the market currently dominated by Intel Corp. and AMD. This is when Tegra may actually start to shine.

Nvidia Corp.’s Shield gaming device has not become popular after about a year on the market. Apparently, neither Google Android games with dedicated controls nor streamed PC titles could attract attention of core gamers. While it was expected that the company would introduce a new, sleeker, version of Shield this year, the company decided to take a more pragmatic approach and introduce a Shield-branded gaming tablet instead.

Nvidia recently certified a product called “Shield tablet” with the Global Certification Forum (GCF) and the Federal Communications Commission (FCC). The tablet will come with integrated 3G/4G baseband capabilities, which is why it needs certification. Since the GCF is a U.K. organization, whereas the FCC is a U.S. commission, expect Nvidia’s Shield tablet to be available in both countries. In fact, it is likely that the slate will be available worldwide.

Nvidia has been testing what it was believed to be the successor of the Shield console for a while now. The new Shield-branded device, which was found in the AnTuTu databank earlier this year, was powered by the Tegra K1 system on-chip with four ARM Cortex-A15 cores (4-plus-1 architecture with one low-power core, clock-rate of the high-performance cores varies between 51MHz and 2524MHz) and Kepler architecture graphics processing unit with 192 stream processors, four ROPs [raster operating units] and so on. The product featured a display with rather odd 1440*810 resolution, 4GB of LPDDR3 memory, 16GB of NAND flash storage as well as Google Android 4.2.2 operating system. It is unknown whether the upcoming Shield tablet has the same specs as the device, which Nvidia tested earlier this year.

Nvidia needed its Shield game console mostly for strategic reasons, not in order to significantly increase its revenue. Nvidia needs Google Android to become a powerful gaming platform in general, which will eventually boost demand for the company’s Tegra application processors for smartphones and tablets. In a bid to attract both core gamers and game developers to Android, Nvidia created an ultimate gaming device, the Shield console. Unfortunately for Nvidia, gamers decided not to buy the gadget since most of Android games are tailored for touch-screens and motion-sensing, not dedicated buttons or D-pad. While hypothetically Nvidia could still release Shield 2 game console, it does not look like it has such plans.

Nvidia did not comment on the news-story.

KitGuru Says: Nvidia’s decision to crease its own Shield tablet for gaming makes a lot of sense since it will help it to demonstrate what Tegra K1 is capable of. What is unclear is how the company plans to differentiate its tablets from similar products from other makers since there are no Tegra K1-exclusive games…

Google this week introduced a new tablet for software developers that belongs to its family of devices supporting the project Tango technologies. The mobile device has Nvidia Tegra K1 application processor inside as well as advanced sensing capabilities that help it to create a 3D model of the environment around it. The specs of the slate give a glimpse on requirements of the Tango technology.

The goal of Google’s project Tango is to give mobile devices a human-scale understanding of space and motion. While the side benefits of the project Tango are advancements in research of robotics and computer vision (something necessary for Google’s self-driving cars), the target applications of the project are mobile devices as well as, hypothetically, wearable computing devices. The Tango is expected to enable multitudes of useful applications for a broad range of needs.

The Project Tango devices feature special hardware (an RGB camera, a motion tracking camera, IR depth sensor(s), motion sensors [gyroscope, accelerometer, speed detection sensor, etc.] as well as special chips/algorithms to process such data efficiently) and software designed to track the full 3D motion of the device, while simultaneously creating a map of the environment. According to Google, the sensors allow the device to make over a quarter million 3D measurements every second, updating its position and orientation in real-time, combining that data into a single 3D model of the space around the device.

google_project_tango_tablet_development_kit_nvidia_tegra_k1

The project Tango tablet development kit is based on Nvidia's Tegra K1 processor and comes with a 7” display with 1920*1080 resolution, 4GB of LPDDR3 memory, 128GB of NAND flash storage, Wi-Fi, Bluetooth 4.0 LE as well as 4G/LTE connectivity. The development kit is designed for professional developers interested in exploring the future of mobile 3D sensing.

Nvidia hints that the project Tango tablet devkit utilizes GPGPU [general-purpose computing on GPUs] compute technologies to create 3D environmental models. At present the company’s Tegra K1 with 192 stream processors based on the Kepler architecture that supports OpenCL is among a few mobile SoCs with GPU-compute capabilities. Given that Google already encourages developers to use GPGPU technologies, it looks like the project Tango-based devices will require powerful graphics processing units.

[yframe url='http://www.youtube.com/watch?v=MTL1IXTDH30′]

The Project Tango tablet development kit goes on sale later this year for $1024.These development kits are not a consumer device and will be available in limited quantities (some believe that only 4000 units will be made). As usually, Google does not indicate when the project Tango evolves into a commercial product.

KitGuru Says: Google’s project Tango is a yet another promising technology from the company. While the project Tango definitely has a lot of potential, just like in case of the project Loon, the Google Contact Lens and other, it is completely unclear when it is set to become a product. Perhaps, the first devices featuring elements of the project Tango will emerge already next year. Or maybe in three years from now? No one knows that for sure.

Nvidia Corp. on Thursday said that it had started volume shipments of its Jetson TK1 development kits, which are based on the company’s highly-anticipated Tegra K1 system-on-chip with four ARM Cortex-A15 cores, Nvidia Kepler-based graphics and a variety of other hardware. The development kit is aimed at designers of software for embedded applications.

Nowadays programs for mobile and embedded apps rely on general-purpose cores (e.g., ARMv7/ARMv8, Intel x86, AMD x86) when performing general-purpose computations. However, many PC applications these days perform highly-parallel GP computations on graphics processing units compatible with application programming interfaces like OpenCL. In the future it will be possible to use mobile GPUs (such as the Kepler core inside the Tegra K1) to perform general-purpose computations as well. The Jetson TK1 is aimed at developers of GPU-accelerated embedded applications, bringing significant parallel processing performance and exceptional power efficiency to embedded applications.

nvidia_tegra_k1_scheme

The Jetson TK1 development kit is a 5” wide by 5” long printed circuit board with a Tegra K1 application processor, 2GB of RAM, 16GB of on-board NAND flash storage and numerous peripherals and input/output ports. The Jetson K1 is capable of supporting multiple cameras through a variety of interfaces, including USB 3.0, Gigabit Ethernet, PCI Express x1 slot. In addition, the CSI 1×4 and 1×1 buses are available through the expansion port and can be used to feed camera images directly into the image signal processor (ISP) on Tegra K1 (bypassing memory), for direct image processing. Up to four cameras cab be used for various computer vision applications.

nvidia_jetson_tk1_devkit

The Jetson TK1 development kit runs Linux for Tegra (L4T), a modified Ubuntu 14.04 Linux distribution provided by Nvidia. The software package supplied with the devkit includes the board support package (BSP) and the software stack that includes CUDA 6 Toolkit, OpenGL 4.4 drivers and the Nvidia VisionWorks Toolkit.

Nvidia hopes that the kit will be used to develop robotics, medicine, security, automotive, and defense applications, among others. Theoretically, at least some GPU-accelerated PC apps could be ported to systems powered by Tegra K1.

Keeping in mind that the development kit is powered by proprietary software, it is hardly possible to create true commercial applications based solely on the Jetson TK1. However, the kit should be sufficient for various experiments.

The Jetson TK1 development kit is available via NewEgg and Microcenter for $192.

KitGuru Says: The fact that Nvidia ships Tegra K1-based development kits via etailers means that the company has enough system-on-chips, which indicates that the mass production of the quad-core ARM Cortex-A15-based version of the SoC has been initiated and the chips are at Nvidia’s hands. Now, it remains to be seen when consumer devices featuring the new system-on-chips arrive to the market…

Although Nvidia Corp.’s first-generation Shield video game console has not managed to become popular, the company is not giving up and is already working on the second-generation system. One of the first prototypes of the new Shield based on Tegra K1 system-on-chip has even been spotted in AnTuTu benchmark database, an indicator that many Shield 2-related design decisions had been finalised.

Based on the information from AnTuTu databank, the new Nvidia Shield 2 is powered by the Tegra K1 system on-chip with four ARM Cortex-A15 cores (4-plus-1 architecture with one low-power core, clock-rate of the high-performance cores varies between 51MHz and 2524MHz) and Kepler architecture graphics processing unit with 192 stream processors, four ROPs [raster operating units] and so on. It is noteworthy that to speed up time-to-market of the Shield 2 Nvidia decided to use the first version of Tegra K1 featuring ARMv7 cores, not the high-performance Tegra K1 with custom Nvidia Denver ARMv8 cores.

nvidia_shield

The test model of the new Shield 2 video game console from Nvidia features 1440*810 display, 4GB of LPDDR3 memory (ARM Cortex-A15 supports 40-bit large physical address extensions [LPAE] tech and can address up to 1TB of RAM), 16GB of NAND flash storage as well as Google Android 4.2.2 operating system.

In case the information is correct, then the Nvidia Shield 2 portable video game console will feature a larger-size display with 1440*810 resolution (the first-gen Shield sported 5” screen with 1280*720 resolution), which will mean a re-worked design as well. While the Kepler-based GPU should feature considerably higher performance compared to custom GeForce core inside the original Shield, Nvidia still decided not to install a full-HD display onto the console.

Expect the Shield to have the same controls as on the first-gen: a touch-screen, a D-pad, two Analog Sticks, L/R bumper and trigger buttons as well as X, Y, A, B buttons. Most likely the Shield 2 will inherit many capabilities of the first-gen console, including 2*2 MIMO 2.4 GHz + 5GHz Wi-Fi 802.11n (802.11ac is possible), Bluetooth 3.0, micro USB 2.0, mini HDMI, 3.5mm audio jack, 3-axis accelerometer, gyroscope, GPS and other things.

Keeping in mind that the original Shield weighs 579 grams (20.42 oz), more than Apple iPad Air, the Shield 2 should probably be lighter and sleeker.

nvidia_shield

While it is hard to say when the new Shield is supposed to be released, it is logical to expect it to be unveiled in early Summer, just when Nvidia promised other Tegra K1-based devices to emerge.

Nvidia did not comment on the news-story.

Discuss on our Facebook page, HERE.

KitGuru Says: When it comes to hardware, the new Shield 2 features were generally expected: Tegra K1, a lot of LPDDR3 memory, the latest version of Google Android, etc. However, specifications do not determine success of products these days. The original Shield could stream/Miracast PC games and play Google Android titles, yet it has not become popular on the market. The main reasons for that were high price and reluctance of gamers to pay a lot to play Android games that run on smartphones and tablets, which a lot of people already own. To make Shield 2 more appealing than its predecessor, Nvidia will either have to sell it at a low price-point (which it cannot do since it does not earn a lot even on exclusive Tegra-optimised games, so it has to make profits on Shield 2 hardware) or ensure that there is a set of AAA titles that run exclusively on Shield (which is a hard thing to do as big publishers want their new games to work on different hardware platforms). All-in-all, while the Shield 2 will be better than the original one, its actual market success will depend on multiple factors and only time will tell whether it will be more successful than the original game console from Nvidia or not.

ARM, the British low power silicon chip maker has announced a new design which uses five times less power than the current processors in today's smartphones. It will perform at a similar level to today's technology.

The company, based in Cambridge said their new Cortex A7 processor is their most efficient design, to date.

Warren East, their chief executive said “This core will enable apps processors at similar levels of performance to what you find in a high-end smartphone today, but in a couple of years that level of performance will be in a lower-end, and therefore a lower cost smartphone. The Cortex-A7 … will help connect the next billion people in developing markets.”

The 28nm design Cortex A7 is fully compatible with the high power Cortex A15 and they can be incorporated onto a single chip. The concept is being called Big.LITTLE and it allows the company to use the A7 for simple tasks and then use the power of the A15 when it is needed. This will help maintain battery life and optimise the overall power consumption of upcoming phones. This hardwware switching can be handled by the operating system.

East spoke to Reuters and said that this new design will help them stay in front of Intel in regards to efficiency. Intel may lead the world in regards to desktop and laptop computers, but they have struggled to tackle ARM in the ultra low power market.

That said, Intel will be releasing the tri gate technology. called Ivy Bridge which might help them gain more ground in this market. East said “Intel made a step forward when they talked about tri-gate technology. Actually those finfets (tri-gate technology) will be available for people to build ARM processors on as well because all the semi-conductor process people are moving in that direction. But at the same time we are moving on a different axis of increased efficiency, and we decided it was time to talk about more than incremental improvements and talk about multiple.”

Kitguru says: Intel V ARM – the fight is coming.
