ARM Interview about Cortex A17 Processor [Video]

When ARM announced their new Cortex A17 core, I could not quite understand why they would release another core with performance and features somewhat similar to Cortex A12 and Cortex A15. Charbax interviewed Nandan Nayampally, ARM VP of Processor Marketing, at Mobile World Congress 2014 and everything is much more clear now. Cortex A17 is based on A12, but adds support for big.LITTLE processing support with Cortex A7, and further improves performance. In some work loads Cortex A17 can currently match Cortex A15 performance, and by 2015, Cortex A17 will have performance similar to A15, and replace it in mid range devices as it has a lower footprint and lower cost. High-end products will switch to 64-Bit with Cortex A53 or A57 next year. The interviewee did not say this explicitly but it could be many companies will simply skip Cortex A12, and directly use Cortex A17, just like Rockchip […]

Yeelight Blue and Yeelight Sunflower Bluetooth Low Energy and Zigbee Smart Light Bulbs for iOS and Android

When it comes Smart light bulbs, which can be dimmed and made to change color, the most popular product must be Philips Hue, using the Zigbee protocol, which you can control via iOS and Android devices though a Zigbee gateway, and costs about $60 on Amazon. Alternative have started to show up such as iLumi Bulbs, with Bluetooth 4.0 Low Energy (BLE) technology, that you can control with recent iOS and Android 4.3+ device without the need for a gateway, but with a price starting at $89. If you’re looking for cheaper alternatives, you’d have to turn to Chinese companies such as Yeelight which provides both Bluetooth LE and Zigbee light bulbs, respectively called Yeelight Blue and Yeelight Sunflower. Yeelight Blue does not require a gateway, but you’ll need a smartphone or tablet that supports Bluetooth 4.0 Low Energy. Recent iOS 5.0+ devices should support it. If your Android device […]

Raspberry Pi Gets Open Source 3D Graphics Drivers and Documentation

The Raspberry Pi was launched 2 years ago, and for its birthday, Broadcom decided to release documentation and open source OpenGL ES 1.1 and 2.0 driver for the Videocore IV GPU. You may remember the Raspberry Pi Foundation already release an open source GPU driver in 2012, but this was only for the part running on the ARM11 core for Broadcom BCM2835 SoC, which is just a few hundred lines of code long, and communicates with a binary blob which does all the work in the GPU itself. This new release however goes much further with a 111 page document entitled “VideoCore IV 3D Architecture Reference Guide“, and open source driver for the 3D System of the GPU. Strangely the release is however not for BCM2835, but instead BCM21553. Broadcom clearly has the source for BCM2835 too, so this must have been made for legal reasons. VideoCoreIV packs a lot […]

Mediatek Smartphone SoC Roadmap Until 2015

Mediatek already has over a dozen of dual, quad and octa processors for smartphone and tablets based on ARM Cortex A7, A9 and A15 cores, and they’ve already announced a 64-Bit ARM SoC (MT6732) as well as MT6595 with four Cortex A17 cores. A leaked product roadmap show the timeline for Mediatek smartphone SoCs, as well as showing some new application processors such as MT6591 Hexa-core SoC, MT6571 dual core Cortex A7 and MT6752 octa core Cortex A53 with LTE. So let’s recapitulate the new and upcoming SoCs from Mediatek: MT6572/M – Dual core Cortex A7 @ 1.3 GHz / 1.0 GHz with qHD/HVGA screen support. Available since Q3 2013, and found in phones such as Cubot GT72. MT6582/M – Quad core Cortex A7 @ 1.3 GHz with HA720/qHD screen support. Available since Q4 2013, found in phones such as W450. MT6588 – Quad core Cortex A7 @ 1.7 GHz […]

$11 Ewell Cubietruck Case Supports 2.5″ SATA Hard Drive and Battery

We’ve already seen a way to make your own HDD enclosure with the Cubieboard, but if you’ve got the latest CubieTruck (aka Cubieboard 3) board with the dual core Cortex A7 AllWinner A20 and 2GB RAM, there’s an easier, and cheaper, way to achieve the same thing with Ewell case that supports 2.5″ SATA Hard drives and SSD, as well as a 5300 mAh lithium battery if you want your system to be portable. The setup is quite interesting as there are few full ARM Linux systems supporting an hard drive on the market, especially at this price point: $11 for the case, and $95 for the Cubieboard. You can either add a 2.5″ Hard drive (320GB / 500GB), or if you are more after performance than storage capacity, a SATA SDD (60 GB) for about $60. Alternatives to this setup would be Compulab Utilite Standard for $159 (Freescale i.MX6 […]

Linaro 14.02 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.02 has just been released with Linux Kernel 3.14-rc3 (baseline), Linux Kernel 3.10.30 (LSK), and Android 4.4.2 r2. There are been a lot of patches for Linaro members boards, and including the latest GTS big.LITTLE processing patch, as well as speeds up to Android 4.4 performance. There’s also a Linux image (password protected) for Huawei D01 board with a 16-core ARM Cortex A15 @ 1.5 GHz SoC with up to 64 GB memory, that must be an unannounced SoC for base stations or other network equipment. This month Linaro also made two important announcements: Qualcomm is now a Linaro member, and the Linaro Security Working Group (SWG) has been setup to develop open source secure software for the ARM architecture. The first projects will be reference implementations of the W3C Embedded Media Extension (EME), and secure boot for the 64-bit ARM Cortex-A series processors. They’ll also work on security […]

Rockchip RK3288 Specifications Released

Somebody working for a Chinese manufacturer informed me Rockchip RK3288 specifications have been released on rk3288.com. We’ve already known the application processor was based on a quad core Cortex A17 processor with a Mali-T76X GPU, but this website provides some more details which appears to have been taken from RK3288 technical reference manual. I can’t confirm the source nor the accuracy of the data, but I doubt somebody would have just put up something with detailed fake information. They mention RK3288 is an application processor destined to be used in high-end tablets, notebooks, all-in-one devices, smart monitors and TV Boxes, and that it features 4Kx2K support.. Let’s have a look at the details. CPU Quad-Core Cortex-A17 Separately Integrated Neon and FPU per CPU 32KB/32KB L1 ICache/DCache per CPU Unified 1MB L2 Cache LPAE (Large Physical Address Extensions), support up to 8GB address space Virtualization Extensions Support DVFS support 3D GPU […]
