Silicon vendor are now launching 8-core and even 12-core processors for mobile devices, and I can see some advantages in terms of power consumption in processors leveraging big.LITTLE processing with low power ‘LITTLE’ cores running light tasks such as audio or video playback, while performance ‘big’ cores running much demanding tasks. However, some processors, such as RK3368, feature the same eight cores, and in real-use don’t bring that extra bit of performance or lower power consumption, except in very specific cases. So the only “advantage” of this type of processor is a marketing one, with keyword like “Octa-core”, “64-bit”, etc… Last year, I found out, that more powerful cores may be more important than many cores, when I tested Allwinner A80 processor with PVRMonitor to check CPU usage per core in real-time, and in Antutu, while Browsing the web or playing games, only a few cores were used most of […]
Connect an Android Smartphone or Tablet to a Monitor, USB Keyboard and Mouse Easily with a DisplayLink Docking Station
Following my post featuring Zenfone 2 Deluxe Special Edition smartphone with 256GB internal storage and 4GB RAM, I had an interesting discussion about mobile and desktop convergence, and we had different views on how this may pan out and what the consumers want, but we all basically agreed this was still work in progress. Another reader pointed me to his various attempts to conveniently connect his Android smartphone and tablet to a large monitor together with keyboard and mouse. He basically considered – and in most cases tested – four choices: Wireless Display solution (Miracast, Chromecast, EZcast…) together with a Bluetooth keyboard and mouse Micro USB port with MHL using a Bluetooth keyboard and mouse Slimport adapter based on MHL but with USB port for keyboard and mouse. Here’s on example of Slimport to HDMI adapter ($10). Displaylink docking station with HDMI and VGA, Gigabit Ethernet, USB 3.0 Wireless display […]

Samsung Artik is a Family of Arduino Compatible Boards for IoT Applications
There was a time when development boards were only reserved to companies, then boards like Arduino or Beagleboard made these available and affordable to consumers, and with the introduction of the Raspberry Pi, the maker movement grew even more rapidly, and many low cost boards started to be designed and manufactured mostly my smallest companies. But now larger companies like Intel or Qualcomm have jumped on the makers’ bandwagon, and the latest entry is Samsung with their Artik platform currently comprised of three boards that are programmable with the Arduino IDE. Let’s go through specifications for the three boards: Artik 1 SoC – Dual Core MIPS32 processor @ 250MHz (microAptiv UP) and 80MHz (microAptiv UC) without GPU Memory – 1MB RAM on-chip Storage – 4MB SPI flash Display – Up to WVGA (800×480) Connectivity – Bluetooth Low Energy with chip antenna Security – Secure element Sensor – 9-axis motion sensor […]
Samsung Galaxy S6 and S6 Edge Octa-core Smartphones Support Two Wireless Charging Protocols and UFS 2.0 Flash
Samsung Electronics announced Galaxy S6 and Galaxy S6 Edge smartphones at Mobile World Congress 2015 during their “Unpacked” event. Both features Exynos 7420 octa-core SoC with 64-bit ARM cores, and 5.1″ display, bit the Galaxy S6 Edge display is curved on both sides. Galaxy S6 & S6 Edge specifications: SoC – Samsung Exynos 7 Octa (Exynos 7420) octa core processor with four Cortex A57 core @ 2.1GHz + four Cortex A53 cores @ 1.5Ghz, and Mali-T760 MP8 GPU, manufactured using 14nm process.

Samsung Introduces Faster Full-Duplex UFS 2.0 Storage for Mobile Devices
eMMC (embedded multimedia card) provides a boost in read and write performance compared to traditional NAND flash memories, let alone micro SD cards. Samsung has now announced the manufacturing of the first 32, 64, and 128GB embedded memory solution based on Universal Flash Storage (UFS) 2.0 standard delivering up to 350MB/s read speed and 150MB/s write speed, or 40% improvement in read speed over eMMC 5.1.This should help further reduce boot time, and app loading times. Moreover, while eMMC read and write operating are sequential (half-duplex), UFS 2.0 allows for full-duplex operating, meaning writing and reading can happen at the same time. UFS can achieve this feat thanks to a LVDS (Low-Voltage Differential Signaling) serial interface with dedicated read/write paths contrary to the parallel 8-bit interface used for eMMC. Combined with a Command Queue(CQ), which sorts out the commands that needs to be carried out, UFS 2.0 allows three times […]
Samsung Z1, the First Commercially Available Tizen Smartphone, Has Launched in India
Tizen operating system is already found in cameras, and smartwatches, with works also being done for televisions, laptops and cars, but the Tizen smartphone has been mostly newsworthy because of product cancellations or delays, rather than product launches. But finally, the first Tizen smartphone has been introduced in India, it’s called Samsung Z1 and sells for 5,700 Indian Rupees ($92). Samsung Z1 (SM-Z130H/DS) specifications: Processor – Spreadtrum SC7727S dual core Cortex A7 processor @ 1.2 GHz with Mali-400 GPU System Memory – 768 MB RAM Storage – 4GB Internal memory + micro SD slot (up to 64GB) Display – 4” WVGA (800×480) PLS screen Cellular Connectivity – GSM 850/900/1800/1900 MHz, HSDPA 900/2100 MHz.

TyGL OpenGL ES 2.0 Backend for WebKit Speeds Up Web Rendering by Up to 11 Times
ARM, Szeged University in Hungary, and Samsung Research UK have been working on TyGL, a new backend for WebKit accelerated with OpenGL ES2.0, and developed and tested on ARM Mali-T628 GPU found in Samsung ARM Chromebook. It will typically provide 1.5 to 4.5 times higher performance, but in the best cases, it can achieve up to eleven times the performance of a CPU-only rendered page. The key features of TyGL include: Web rendering accelerated by GPU – Batching of draw calls delivers better results on GPUs. TyGL groups commands together to avoid frequent state changes while calling the Graphics Context API. Automatic shader generation – TyGL generates complex shaders from multiple shader fragments, and ensures the batches fit into the shader cache of the GPU. Trapezoid based path rendering – Work in progress. It will leverage GPU capabilities such as the Pixel Local Storage extension for OpenGL ES. No software […]
