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 […]

ODROID-XU3 Lite Board Ubuntu Review – Setup, Usability, and Performance

After testing ODROID-XU3 Lite with Android 4.4, and finding a workaround to some HDMI issues, I could finally try out Ubuntu, or rather Lubuntu with LXDE instead of Unity, in Hardkernel low cost octa-core development board. I’ll start this review by explaining how to install and setup Lubuntu on the board, followed by running various program to test the system usability as a desktop computer with LibreOffice, Chromium, XBMC, and 3D graphics, and finally run some performance tests with Phoronix Test Suit, build the Linux kernel natively, and transcode a video with avconf. Setting Up Ubuntu on ODROID-XU3 Lite All firmware images for ODROID development boards, can be found on odroid.in website, and if you want Ubuntu 14.04 image, go to ubuntu_14.04lts folder, to select the latest firmware file for your board. The latest image for ODROID-XU3 (Lite) is currently ubuntu-14.04.1lts-lubuntu-odroid-xu3-20141105.img.xz, it’s the same for micro SD card or eMMC […]

Linux 3.18 Released

Linus Torvalds released Linux Kernel 3.18 last Sunday: It’s been a quiet week, and the patch from rc7 is tiny, so 3.18 is out. I’d love to say that we’ve figured out the problem that plagues 3.17 for a couple of people, but we haven’t. At the same time, there’s absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn’t make sense. Especially since that would just have then held things up entirely over the holiday break. So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that “Ahaa” moment) over the next week. But in solidarity with Dave (and to make my life easier too 😉 let’s try to avoid introducing any _new_ […]

Hardkernel ODROID-C1 is a $35 Development Board Powered by Amlogic S805 Quad Core Processor

Amlogic S805 is a quad core Cortex A5 processor which has found it way into low cost devices such as MK808B Plus TV Stick which can be purchased for as low as $30, or full-sized TV box such as MXQ S85 or MINIX NEO X6. All this low cost devices are nice, but the full source code is not available in your want to adapt them to your need. Luckily, Amlogic releases both an Android SDK, and a buildroot for Linux with GPU and Video Processing Unit (VPU) support, so Hardkernel decided to go ahead, designed a board, and has just launched ODROID-C1 quad core development board for just $35, or the exact price of a Raspberry Pi Model B+, but with much greater specs. ODROID-C1 specifications: SoC- Amlogic S805 quad core Cortex-A5 processor with a Mali-450MP2 GPU (2x fragment cores + 2x vertex shader cores) System Memory – 1GB […]

Fujitsu MB86S70 and MB86S73 ARM Cortex A15 & A7 Processors Run Linux for the Embedded Market

I like to check the ARM Linux kernel mailing list from time to time, as you may discover a few upcoming ARM processors. This week I found out Exynos 5433 and Exynos 7 are actually two different processors (thanks David!), and that AMD had submitted code for their 64-bit ARM Opteron A1100 SoC for servers. I also noticed a patchset for Fujitsu MB86S7X SoCs, and since I don’t often mention Japanese silicon vendors, probably because they now mainly deal mostly with the embedded market that gets very little press, and most information is in Japanese, I decide to have a look. There seems to be four SoC parts in MB86S7x family with MB86S70 quad core processor with two ARM Cortex A15 and two ARM Cortex A7 cores in big.LITTLE configuration, and MB86S73 with two ARM Cortex A7 cores only, as well as MB86S71/72 with 2x A15 and 2x A7, with […]

Imagination Technologies Introduces PowerVR Series7 GPUs with Up to 512 Cores, Virtualization Support

Imagination Technologies has announced a new PowerVR Series7 GPU architecture that will be used in their high end PowerVR Series7XT GPUs delivering up to 1.5 TFLOPS for mid range and high-end mobioe devices, set-top boxes, gaming consoles and even servers, as well as their low power lost cost PowerVR Series7XE GPUs for entry-level mobile devices, set-top boxes, and wearables. PowerVR Series7 GPU, both Series7XT and Series7XE GPUs, can achieve up to a 60% performance improvement over PowerVR Series6XT/6XE GPUs for a given configuration. For example a 64-core PowerVR7XT GPU should be up to 60% faster than a 64-core PowerVR Series6XT clocked at the same frequency, with all extra performance due to a different and improved architecture. Some of Series7 architectural enhancements include: Instruction set enhancements including added co-issue capability, resulting in improved application performance and increased GPU efficiency New hierarchical layout structure that enables scalable polygon throughput and pixel fillrate […]

Qualcomm Releases Userspace Adreno 320 GPU Drivers for Ubuntu

Qualcomm Developer Network has just sent the October Newsletter by email, and they had some news specific to Ubuntu / Linux support on IFC6410 development board powered by a Snapdragon 600 processor. Firs they link to a guest blog post on Qualcomm website entitled “Video Conferencing on Linux with the Qualcomm Snapdragon 600 Processor“, where Qualcomm partner eInfochips stated: Qualcomm Technologies, Inc.’s leadership in mobile market with Linux Android support is well established. As the demand for Qualcomm Snapdragon processors, a product of Qualcomm Technologies, Inc., increase in adjacent markets, the need for non-Android Linux support becomes evident. Which is always good to read. The rest of the post blog provides a few more details about their a low-latency (50ms glass-to-glass) video conferencing solution based on OpenEmbedded build with Linaro Linux Kernel, and making use of Qt5, Gstreamer, and Sofia SIP library. Further improvements will be achieved with hardware video […]

ARM Unveils Mali-T800 Series GPUs, Mali-V550 VPU, and Mali-DP550 Display Processor

ARM has just announced several new Mali media IP: three Mali-T800 series GPUs (Mali-T820, Mali-T830, and Mali-T830) based on Midgard architecture, as well as Mali-V500 video accelerator, and the Mali-DP550 display processor. Mali T800 Series GPU The new Mali T-8xx GPUs are based on the same Midgard architecture used in Mali T-6xx and T-7xx GPUs, but deliver better power efficiency thanks to technologies such as ARM Frame Buffer Compression (AFBC), and Adaptive Scalable Texture Compression (ASTC) for imput bandwidth reduction, as well as Transaction Elimination and Smart Composition. ARM provided some performance and energy-comparison between T800 and T600 series (but strangely nothing against T700): The Mali-T820 GPU is optimized for entry-level products, achieving up to 40 percent more performance density compared to the Mali-T622 GPU. The Mali-T830 GPU delivers up to 55 percent more performance than the Mali-T622 GPU. The Mali-T860 GPU provides higher performance and 45 percent more energy-efficiency […]
