Nufront 2GHz ARM Cortex-A9 for Desktop, Laptop and Netbook – NuSmart 2816

Nufront (新岸线) is a high tech company based in Beijing, dedicated to wireless broadband communication and broadcast, IC design, video search and digital imaging technologies. Nufront showed off their “low-power high performance” mini-PC based on their new NuSmart 2816 chipset at ARM Techcon 2010. NuSmart 2816 is based on a dual-core Cortex-A9 @ 2GHz with Mali-400 GPU. They plan to sell the chip for around 30 USD and expect ARM-based mini-PC to sell for around 200 USD retail. You can download NuSmart 2816 Product Brief for further details. As you can see from the diagram below, NS2816 can support all features (Ethernet, Wifi, GPS, USB, I2S Audio, SATA II, MMC/SD support, VGA, HDMI or LCD video output) that are now expected in modern desktops or laptops. Video playback currently uses around 2 Watts (chip samples) and they target 1.5 Watt for video playback in the final release of their chipset […]

ARM Based Embedded Server – Marvell ARMADA XP

A few years ago, nobody would have considered using an embedded system to run a server. But now, with the advance of technology, more and more servers are running embedded systems from the lower end such as home-based NAS (Network Access Storage) to higher-end for data-centers, cloud computing, web 2.0… This is the higher-end that Marvell targets with its Quad Core ARM ARMADA XP MV78460 running at 1.6GHz with “16,600 DMIPS performance at less than 10 watts”. Please checkout Marvell ARMADA XP Product Brief for further details. The main selling point of such solution is the power consumption compared to traditional Intel x86 based servers. According to Marvell, 50% of the cost of running a data-center is the electricity bill to run the server and especially to cool the room with air-conditioners. So let’s do a little exercise. Let’s take the estimated power consumption of Google data-center in Oregon that […]

ARM Android Based Rubiks Cube Solver

David Gilday – a chip designer at ARM – has got two hobbies: Playing Lego and Rubik’s Cube. He must have been tired to turn the sides of the game manually so he designed a robot to solve the Rubik’s Cube within an average of 15 seconds. So here’s how it works: A Robot built with Legos using 6 motors and an Android phone connected to it. He’s using an ARM11 platform running Android (Looks like a Google Nexus One to me). You mix the Rubik’s Cube, place it in the middle of the robot, then it starts.. the smartphone scans all faces of the Rubik’s Cube (with the back camera of the phone), an algorithm calculates the moves (using a 300MB database), then the robot turns the Rubik’s Cube to solve the puzzle and finishes with a nice spin once the 3D-puzzle is solved. The algorithm is written in […]

Samsung Orion ARM Cortex A9 – Nexus S

Samsung recently showed off its dual-core Cortex-A9 Orion featuring quad-core Mali-400 GPU at Techcron 2010. The Samsung Orion (model name: S5PV310XH) will run at 1GHz (this frequency might be increased later on: I’ve read 1.2 GHz, 1.5GHz or even up to 2 GHz.) and use 45nm lower power manufacturing technology. Samsung already have a BSP using Linaro kernel and the development board having the following characteristics: Samsung Orion SoC Low power audio subsystem Embedded GPS 2D Graphics Acceleration TFT 24-bit true color LCD Controller MALI-400 3D Graphics TV-out and HDMI interface support Multi-format codec up to 1080p @ 30fps The device would runs Android on top of Linaro kernel which takes care of all the low level stuffs. If you are interested in developing for this platform, you can already download and play around with Linaro 10.11 which already supports Cortex A8 and A9 platforms. The Samsung Orion is rumored […]

Digital Signage Standard: Open Pluggable Specification (OPS)

A while ago, we discussed about Popai Digital Signage Standards, mainly focused on software and client/server interoperability. Intel has just released a new standard for Digital Signage: Open Pluggable Specification (OPS). Here’s the description of the specification on Intel website. The Open Pluggable Specification (OPS) helps standardize the design and development of digital signage devices and pluggable media players. Intel created the OPS to address digital signage market fragmentation and simplify device installation, usage, maintenance and upgrades. The OPS enables digital signage manufacturers to deploy interchangeable systems faster and in higher volumes, while lowering costs for development and implementation. Installing digital signage equipment based on Intel® architecture helps you implement scalable digital signage applications that can network easily with other equipment. This simplifies interoperability and application upgrades designed to meet the digital signage requirements of individual customers, while helping to future-proof technology investments. You’ll need to fill a form to […]

Resources for Qualcomm MSM722x: MSM7225, MSM7227

Qualcomm MSM722x processors – part of MSM (Mobile Station Modem) series – are mainly used in mobile phones and to a lesser extend in tablets such as WellCoM A800. You won’t find any proper documents or information in Qualcomm website (see Qualcomm MSM page) except the following description: Qualcomm’s Mobile Station Modem™ (MSM™) chipset solutions enable cost-effective mobile handsets with advanced capabilities that leverage 3G technology yet minimize development time. Offered on four discrete platforms for tailored functionality, each chipset is integrated with a select set of features from Qualcomm’s multimedia suite of applications to enrich the user experience while maintaining cost-target objectives. So if you plan on developing on that platform, you’ll need to visit Qualcomm developer website to get most of the information you’ll need. There are two chipsets with similar characteristics. MSM7225 The MSM7225 chipset includes a 528 MHz ARM11 processor with a floating point unit (FPU). […]

WellcoM WePad A800 Android 2.2 Tablet Video Review

More and more decent (e.g. with capacitive multi-touch screen, decent processor…) and cost-effective android tablets are hitting the market such as Archos Gen8 Series. It might be difficult to obtain Archos 70 in some countries in Asia. But not is all lost as product such as the WellcoM WePad A800 are available in Thailand (and probably other countries). This tablet based on Qualcomm MSM7227 @ 600 Mhz runs on Android 2.2. The device comes with 512 MB DDR RAM, 512 MB Rom, a 7″ multi-touch capacitive touch screen (800 x 480) , Wifi, Bluetooth, 2G/3G network support. I discovered this product in a shop in Chiang Mai yesterday. I tried it a bit, it was very smooth and responsive. It sells for 15900 Baht (530 USD / 383 Euros) with a free bluetooth headset. The following videos (In Thai only) reviews the device. The reviewers runs a lot of benchmark […]

Accurate Time Keeping in Embedded Systems

In many embedded systems, there is a need to keep accurate time/date. This is often performed using an RTC (Real-Time Clock). However, uncalibrated RTC are not that accurate. For example, ST Microelectronics M41T94 RTC datasheet explains that: Uncalibrated clock accuracy will not exceed ±35 ppm (parts per million) oscillator frequency error at 25°C, which equates to about ±1.53 minutes per month. . In order to improve the accuracy, you’ll need to calibrate the crystal for each board at the factory using a frequency counter, that will greatly improve accuracy, for M41T94: When the Calibration circuit is properly employed, accuracy improves to better than ±2 ppm at 25°C. However, calibrating the crystal will further increase the manufacturing costs. Another way to have a very accurate time keeping, is to use the power supply frequency (50 Hz/60 Hz) which is extremely accurate due to interoperability requirements between electricity providers. In the diagram […]
