Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4. Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month. Here are the highlights of this release: Linux Linaro 3.17-rc4-2014.09 GATOR version 5.19 updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express […]
Some Projects on Nvidia Jetson TK1 Development Board: Nintendo Emulator, USB3 Webcam, and Robotics
Nvidia Jetson TK1 is a development board powered by the company’s Tegra K1 quado core Cortex A15 processor, and especially a Kepler GPU that allows for OpenGL 4.4. It has shipped to developers around April/May, and some of them have showcased their projects, or tested some hardware. Dolphin Emulator on Nvidia Jetson TK1 Dolphin is an emulator for Nintendo GameCube and Wii console that supports full HD (1080p) rendering, and run on Android, Linux and Mac OS, and there’s also an Alpha version for Android. Ryan Houdek (Sonicadvance1), one of Dolphin’s developers, has leveraged Kepler’s OpenGL support via Nvidia’s GPU drivers, to port the emulator to the platform running on Ubuntu, but it should work as well on Tegra K1 hardware running Android such as XiaoMi MiiPad tablet. You can watch Mario Kart: Double Dash demo running at full speed on the Nvidia board below. According to the developer, such […]
ARM TechCon 2014 Schedule – 64-Bit, IoT, Optimization & Debugging, Security and More
ARM Technology Conference (TechCon) 2014 will take place on October 1 – 3, 2014, in Santa Clara, and as every year, there will be a conference with various sessions for suitable engineers and managers, as well as an exposition where companies showcase their latest ARM based products and solutions. The detailed schedule for the conference has just been made available. Last year, there were 90 sessions organized into 15 tracks, but this year, despite received 300 applications, the organizers decided to scale it down a bit, and there will be 75 session in the following 11 tracks: Chip Implementation Debugging Graphics Heterogeneous Compute New Frontiers Power Efficiency Safety and Security Software Development and Optimization Software Optimization for Infrastructure and Cloud System Design Verification There are also some paid workshops that take all day with topics such as “Android (NDK) and ARM overview”, “ARM and the Internet of Things”, or “ARM […]
Imagination Technologies Unveils Low Power Low Footprint PowerVR GX5300 GPU for Wearables
Up to now most wearables are based on MCU solutions or derived from mobile platforms, which may either not provide the advanced features required by users, or consume too much power and take more space than needed. With Ineda Dhanush and Mediatek Aster, we’ve already seen silicon vendors design wearables SoCs, and now Imagination Technologies has just announced PowerVR GX5300 GPU targeting wearables with support for OpenGL ES 2.0, 480p to 720p resolution, and using 0.55mm2 silicon area based on 28nm process. PowerVR GX5300 GPU will be support Android, Android Wear, and Linux based operation systems, and according to the company has the following key features: Unified shaders – The TBDR graphics architecture offers unified shaders where vertex, pixel and GPU compute resources are scaled simultaneously. Low power and high precision graphics – All PowerVR GPUs offer a mix of low (FP16) and high precision (FP32) rendering and implement the […]
Hardkernel Unveils $179 ODROID-XU3 Development Board Powered by Samsung Exynos 5422 SoC
Remember ODROID-XU2 development board based on Exynos 5420? The bad news is that it apparently got scrapped, but the good news is that it gave birth to ODROID-XU3 development board powered by the latest Samsung Exynos 5422 octa core big.LITTLE SoC with support for Ubuntu 14.04 and Android 4.4, including GPU 3D acceleration with the company promising a full desktop experience in Ubuntu. ODROID-XU3 specifications: SoC – Samsung Exynos 5422 quad core ARM Cortex-A15 @ 2.0GHz+ quad core ARM Cortex-A7 @ 1.4GHz with Mali-T628 MP6 GPU supporting OpenGL ES 3.0 / 2.0 / 1.1 and OpenCL 1.1 Full profile System Memory – 2GB LPDDR3 RAM PoP (933Mhz, 14.9GB/s memory bandwidth, 2x32bit bus) Storage – Micro SD slot (up to 64GB) + eMMC 5.0 module socket (16, 32, or 64GB module available) Video Output – micro HDMI (Up to 1080p) and DisplayPort (up to 2160p) Audio Output – micro HDMI and […]
Google Releases Android L (Lollipop?) Developer Preview
Google I/O is taking place right now in San Francisco, and the company made several announcements. Although they have not announced the full codename of Android 5.0, referring to the next version as “Android L” (Lollipop would be nice though), but they’ve already documented the key changes made to Android L, and a developer preview will be released later today (26 June), together with binary images for Google Nexus 5 and Nexus 7. Beside the smartphone and tablet developer preview, there will be 3 other SDKs for Android L: Android Wear SDK – Android for wearables with sync notifications, wearable apps, data transfer APIs, and voice actions, e.g. “Ok Google, call mum”. Android TV Preview SDK – Android for TVs with pre-built fragments for browsing and interacting with media catalogs, in-app search, and recommendations. Android Auto SDK – Android for the car with apps featuring consistent user experience between vehicles, […]
ARM Cortex A15/A17 SoCs Comparison – Nvidia Tegra K1 vs Samsung Exynos 5422 vs Rockchip RK3288 vs AllWinner A80
We’re now starting to get quite a few players with ARM Cortex A15 cores on the market, as well as some with ARM Cortex A17. So a comparison table of different quad and octa SoCs might be a useful thing to do. I’ve put aside SoCs such as HiSilicon K3V3, and OMAP5, and focused on the four latest processors: Nvidia Tegra K1 (32-bit), Samsung Exynos 5422, Rockchip RK3288 and AllWinner A80. I haven’t included Mediatek MT6595 and Qualcomm SnapDragon 805, because the two companies mainly focus on smartphones and tablets (although it appears to be slowly changing for Qualcomm), documentation is usually difficult or impossible to find, and in the case of Qualcomm they use their own ARMv7 Krait cores. I’ve highlighted some features in green, in case a particular SoC appears to have an edge. Rockchip RK3288 AllWinner A80 Nvidia Tegra K1 Samsung Exynos 5422 CPU 4x ARM Cortex-A17 […]
AMD Unveils Low Power Mobile “Mullins” APUs for Tablets and Hybrid Laptops
AMD has announced its 3rd-generation Mainstream and Low Power Mobile Accelerated Processing Units (APUs), codenamed codenamed “Beema” and “Mullins,” respectively, featuring four x86 Puma+ CPU, AMD Radeon graphics, and a platform security processor (PSP) with an ARM Cortex-A5 core for ARM TrustZone security. Beema APUs have a TDP between 9W and 15W, whereas Mullins APUs all have less than 5W TDP (2.8W SDP). So I’ll only cover cover Mullins processors in this post, as they may offer an alternative to Intel Bay Trail-T processors. There are now 3 more APUs part of AMD’s tablets and 2-in-1 solutions: A10 Micro-6700T, A4 Micro-6400T, and E1 Micro-6200T. They are highlighted in green in the table below, and compared to previous generations: Model Radeon Brand CPU Clock Speed (Max/Base) CPU Cores on Die TDP Total L2 Cache GPU Clock Speed (Max/Base) DDR SDRMA Max Memory Speed A10 Micro–6700T Radeon R6 2.2 GHz 4 4.5W 2MB […]
