Tizen Releases Beta Source Code and SDK

Back in January, Tizen preview SDK and source code was made available. Today, Tizen has released the beta source code and SDK. Here are the main changes compared with the code preview: SDK support for Windows, in addition to Ubuntu SDK source code is now available Tizen Web UI framework extends jQuery Mobile to make developing web applications easier with optimized widgets. Tizen Web API provides more features, such as setting an alarm, accessing media contents, retrieving system information, and more. Tizen uses a bootloader based on U-Boot. The Tizen team emphasizes that this version is Beta and that it is not yet designed for use to create production applications. Since Windows is now supported, the development machine requirements have slightly changed as follows: Ubuntu 10.04/10.10/11.04/11.10 32-bit, Windows XP SP3/7 32-bit (Mac version will be available soon) At least dual-core 2 GHz CPU (recommend VTx supported by CPU) At least […]

Texas Instruments OMAP5 Demo at MWC 2012

Charbax of armdevices.net has uploaded a very interesting video with an OMAP5430 demo and an interview at Texas Instruments booth at MWC 2012. Using the OMAP5 development kit, they demo several 3D applications, the web browser and the picture gallery and it looks extremely smooth. They discussed about the OMAP5 vs Tegra 3 benchmark, and it appears mobile web browsers are not yet optimized for more than 2 cores which could explain the performance difference somewhat. The OMAP5 currently runs at 800 MHz, but there will eventually be 2 versions: 1.7 and 2.0 GHz when the OMAP 5 AP is released. This should show a performance improvement of over 4x against the Tegra 3, although I’m sure in the meantime, Nvidia will have announced the Tegra 4 (Wayne). The OMAP 5 also offers impressive improvement in power consumption, as the SGX544 GPU cores are augmented by a dedicated 2D hardware-accelerated […]

Linux on eMMC: Optimizing for Performance – ELC 2012

Ken Tough, principal engineer at Intrinsyc Software, discusses Linux on eMMC at Embedded Linux Conference 2012. Abstract: Embedded devices are increasingly choosing eMMC instead of raw NAND flash as their main storage, for increased independence from component vendors and changing storage densities. This presentation examines Linux configuration for eMMC, how to effectively measure your eMMC performance, and tips to improve it. Topics covered include: filesystem bearing on MMC/SD performance, IO scheduler configuration, and optimal partition layout. Target audience is embedded systems developers or users interested in getting the most out of their eMMC/SD card. You can also download the presentation slides on elinux.org.

HTML5 in a Plasma-Active World – ELC 2012

Danny Bennett, Principal Engineer at basysKom GmbH, talks about HTML5 in Plasma Active development environment at Embedded Linux Conference 2012. Abstract: With the explosion of mobile application development, there is a increasing demand for a common run-time environment across the many mobile platforms. The WAC (Wholesale Applications Community) along with the latest W3C (World Wide Web Consortium) HTML (Hypertext Markup Language) specification HTML5 (HTML version 5) is a step in that direction. Using recent advances in widget/web application development tools and techniques such as Qt Quick and JavaScript. Using Plasma Active as a development environment we can show how to build and verify widget WAC compliancy using the online compliancy verification. This is done using the current version of Plasma-Active running on MeeGo, Mer and the upcoming Tizen platforms. Proving MeeGo, Mer and Tizen are good platforms as a basis to create WAC compliant HTML5 based web applications. You can […]

HiSilicon Unveils Quad-Core Cortex A9 K3V2 Processor (Hi3620)

HiSilicon, a subsidiary of Huawei, has unveiled the K3V2 quad-core cortex A9 processor at mobile world congress 2012, Barcelona. The processor comes in two version 1.2 and 1.5 GHz and the company claims the chip delivers 30 to 50 percent more performance than existing quad-core processor including the NVidia Tegra3. This performance boost is apparently possible thanks to a 64-bit memory bus as well as a powerful 16-core GPU (by an unnamed US chip designer) that is at least twice as fast as the competition. The current versions of the chip are manufacturer using TSMC 40 nm low power process, but the company plans to move to 28-nm technology for further power efficiency later this year. They do not use a companion core like the NVidia Tegra 3 to save power, but instead HiSilicon designed an A.I.PS (Artificial Intelligence Power Scaling) Core in K3V2, which can manage cores CPU and […]

Qualcomm Showcases Glasses-Free 3D Tablet Powered by SnapDragon S4 Processor

Mobile World Congress 2012 starts today and we should get a flood of announcements today. In the video below, Qualcomm showcases their Snapdragon S4 quad-core processor in a developer tablet showing 4 independnat videos decoded by the 4 cores and a 3D game demo taking advantage of the faster GPU (50% faster than the previous generation). They also showcase the Snapdragon S4 dual-core MDP Tablet with Full High-Definition glasses-free 3D display in WUXGA (1920×1200) resolution. This tablet also has 2 8MP rear camera in order to capture 3D movies and photos.

The Power of SPDX (Software Package Data Exchange) – ELC 2012

Mark Gisi, Sr. Manager of Intellectual Property at Wind River , discusses SPDX (Software Package Data Exchange) at Embedded Linux Conference 2012. Abstract: Sharing Critical Licensing Information within a Linux Device Supply Chain Embedded Linux device runtimes are derived from 100s of open source packages. A common misunderstanding is that just one or two licenses govern a given open source package, when in fact; often a dozen or more apply. Therefore a device runtime could be under 100s of unique licenses. Determining which licenses are relevant is challenging. SPDX, the Linux Foundation’s license exchange format, provides an effective mechanism for recording and sharing licensing information within a device vendor supply chain. We present an overview of SPDX along with a detailed source code example on how to create and extract relevant licensing information. The target audience includes developers, engineering managers, release operation engineers and license compliance professionals. They will learn […]

Adapting Your Network Code For IPv6 Support – ELC 2012

Mike Anderson, CTO and Chief Scientist at The PTR Group, discloses how to bring your network code up to speed for IPv6. Abstract: IPv6 support is no longer a “sometime in the future” thing. We’ve exhausted the IPv4 address space and need to start transitioning our code to support IPv6. But, is this a big thing or a little thing? This presentation will outline the typical changes that need to be made to networking code to support IPv6 and describe transition strategies to enable use in a dual-stack environment. The target audience for this presentation is developers who want to take advantage of the new IPv6 address space. This presentation is targeted at intermediate-level developers with some understanding of the IP protocol stack.
