Hardkernel is Working on ODROID-XU Development Board Based on Exynos 5410 Octa Core Processor

Hardkernel have already done a good job at bringing low cost, high performance development boards based on Exynos 4 Quad processor with boards such as ODROID-X, ODROID-U2, or ODROID-X2. But it appears they are not stopping here, and have recently committed code to support ODROID-XU development board based on Exynos 5410, the 8-core big.LITTLE SoC from Samsung, used in devices such as Galaxy S4. The committed code linked above point the device tree files in arch/arm/boot/dts/ (exynos5410-odroidxu.dts and exynos5410-pinctrl.dtsi) where we can see the board will have 2 GB RAM, and the Cortex A15 cores with be clocked at 1.6 GHz. Exynos5410-odroidxu.dts has been removed from 3.11 branch, so the link above points to an earlier commit. Exynos 5410 might have been the first big.LITTLE processor ever available, but it comes with a major flaw, as it only supports cluster migration (all 4 Cortex A15 or all 4 Cortex A7 […]

Mediatek Boasts True Octa-core MT6592, and GTS big.LITTLE MT8135 SoCs

We already knew Mediatek was working on MT6592, an Octa-core Cortex A7 processor for smartphones, and MT8135, a quad core bit.LITTLE processor for tablets, but in the last few days, the company revealed a bit more information about its two new application processors, mainly to show how better there are compared to the competition. Mediatek MT6592 Octa-core Cortex A7 With Exynos Octa (5410), Samsung was the first company to release an ARM powered Octa-core application processor, but Meditak explains their solution is better because MT6592 can use all 8 cores simultaneously whereas Exynos 5410 is limited to 4 at at time, and the claim is true because Samsung big.LITTLE implementation choice. Exynos 5420 will change that however, as soon as this month, but Mediatek obviously did not feel necessary to mention this details. The company expected those 8 cores to improve current applications such as : Advanced web browsing – […]

Tizen Developer Conference 2013 Presentation Slides, Audio Recording and Videos Are Now Available

The Tizen Developer Conference took place in San Fransisco, on May 22-24, 2013. We’e already seen a few Tizen demos from the conference, but slides and media files (mostly audio, but also some videos) are now available for keynotes and technical presentations. As this was just the second Tizen conference, there were still many sessions dealing with overall structure of the operating system, and explaining how to get started either with native or web development, such as: An Overview of the Tizen Native Application Framework Introduction of Tizen SDK minimal web development tools Tizen Design Guidelines and User Experience Tizen Overview and Architecture Tizen.org Web Infrastructure Tizen enters a mobile world dominated by Android and iOS, so several sessions targeted app developers used to work with either operating systems in order to show them how to port their existing apps to Tizen: Bringing Android Apps to Tizen From iOS to […]

LG Optimus L4II is a Triple SIM Smartphone Powered by Mediatek Technology

There’s already an impressive number of mobile phones with dual SIM card slots, but LG and Mediatek went a step further with the Optimus L4II that sports triple SIM card support thanks to Mediatek 3G Triple-SIM technology. All three SIM cards can be “used simultaneously, and receive calls, transmit data, send SMS messages and remain in standby mode concurrently without consuming excessive battery life”, according to Mediatek. If case you wonder why people would ever need multiple SIM card use cases include roaming between different countries (e.g. Hong Kong, Macau and China) where you don’t want to change SIM cards each time you cross the border, using prepaid SIM cards from different telco to benefit from promotion, etc… I could not find the other specs for the device, but the company has recently launched LG Optimus L4II Dual (dual SIM card support) which may be similar, with the following specifications: […]
