Linux Kernel Mainline Status of Mobile SoCs Presentation at Linaro Connect SF015

Linaro Connect San Francisco 2015 is taking place this week, and several 96Boards have been presented including LeMaker Hikey and Qualcomm DragonBoard 410c, both of which will finally be available by the end of the year. But there are also many technical presentation and discussions that are uploaded to LinaroOnAir Youtube account, and they’ve greatly improved video and audio quality compared to the past, with presentation slides also available on Slideshare. I’ve just watched one of the session entitled “Kernel Mainline Status of Mobile Chipsets” by Tim Bird, Sony Mobile. Also the talk focus on mobile SoC, it’s also relevant to other consumer electronics products, and some embedded systems. The presentation states the extend of the issues, shares comparisons between the vendor device tree and mainline, and explains how developers can participate, with the talk ending with a discussion within the group of attendees. Here’s a summary of some of […]

Brotli Compression Algorithm Combines High Compression Ratio, and Fast Decompression

After Zopfli, Google has now announced and released Brotli, a new compression algorithm to make the web faster, with a ratio compression similar to LZMA, but a much faster decompression, making it ideal for low power mobile devices. Contrary to Zopfli that is deflate compatible, Brotli is a complete new format, and combines “2nd order context modeling, re-use of entropy codes, larger memory window of past data and joint distribution codes” to achieve higher compression ratios. Google published some benchmark results comparing Brotli to other common algorithms. Since the company aims to make the web faster, the target is to decrease both downloading time (high compression ratio), and rendering time (fast decompression speed), and Brotli with a quality set to 11 is much better than competitor once both parameters are taken into account. As you’d expect the source code can also be pulled from Github. So I gave it a […]

MagicStick TV Sticks Powered by Intel Atom x5 or x7 Processors Feature up to 8GB RAM, HDMI 2.0, 802.11ac… (Crowdfunding)

Several Cherry Trail Atom x5 MegooPad TV sticks are on the way, but they mostly have similar specs to the previous generation Bay Trail sticks, except with a slightly faster processor, and in some models, USB 3.0 support. An Indian company is currently developing some Cherry Trail TV sticks with impressive specifications including processors such as Intel Atom x7-Z8700, up to 8GB RAM, up to 64GB storage, 802.11ac connections, HDMI 2.0, and USB 3.1 type-C connector. These products are called MagicSticks, and three models will soon be available. [Update 30/9/2015: The indiegogo campaign is up, but the Wave is not shown, and instead MagicStick Power has been renamed to Wave, changes are reflected in the table below] MagicStick One MagicStick Wave MagicStick Power Wave Processor Intel Atom x5-Z8300 processor up to 1.83 GHz, with 12 core Gen8 GPU Intel Atom x5-Z8500 processor up to 2.24 GHz, with 12 core Gen8 […]

LeMaker Hikey 96Boards Development Board Comes with 1 to 2GB RAM, Sells for $75 and Up

Hikey was the first 64-bit ARM development board compliant with 96Boards specifications, and supported by Linaro. Availability always seemed to be an issue however, and pricing was set to $129. But Lemaker, the makers of Banana Pi boards, recently joined Linaro, and they’ve built a lower cost version of the Hikey board, still featuring Hisilicon Kirin 620 octa-core ARM Cortex-A53 processor, but with 1GB and 2GB RAM versions, priced respectively at $75 and $99. LeMaker Hikey board specifications: SoC – HiSilicon Kirin 620 octa core Cortex A53 processor @ 1.2 GHz with ARM Mali-450MP4 GPU System Memory – 1 or 2 GB LPDDR3 @ 800 MHz Storage – 8GB eMMC + micro SD slot Video Output / Display – HDMI up to 1080p, MIPI-DSI interface Connectivity – 802.11 a/b/g/n Wi-Fi, Bluetooth 4.1 LE (WL1835MOD module) USB – 2x USB 2.0 host ports, 1x micro USB OTG Camera – MIPI CSI […]

A Look at Android and Windows Mini PCs’ Power Consumption in Power Off, Standby, Idle, and Video Playback Modes

I’ve previously measured power consumption of Amlogic S812 and Rockchip RK3288 based TV boxes using a multimeter. This provides relatively accurate measurements, as well as neat power consumption profiles of devices, but it’s a little complex and time-consuming, so it’s not something I would do for all devices. The easiest way to measure power consumption is to use a kill-a-watt type of device, but my first one broke after only 3 months last year. I purchased a new one recently, so I run run some power measurement tests on several devices. I selected five devices for this test: MeLE PCG01 HDMI stick with Intel Atom Z3735F processor running Windows 10 Zidoo X9 TV box with Mstar MSO9810 running Android 4.4 Open Hour Chameleon TV box with Rockchip RK3288 processor running Android 4.4 Tronsmart Orion R68 Meta TV box with Rockchip RK3368 processor running Android 5.1 Tronfy MXIV TV box with […]
