OpenCL Accelerated SQL Database with ARM Mali GPU Compute Capabilities

We’ve previously seen GPU compute on ARM could improve performance for mobile, automotive and consumer electronics application. GPU compute offload CPU task that can be parallelized to the GPU using APIs such as OpenCL or RenderScript. Most applications that can leverage GPU compute are related to media processing (video decoding, picture processing, audio decoding, image reconigion, etc…), but one thing I did not suspect could be improve is database access. That’s what Tom Gall, Linaro, has achieved in a side project by using OpenCL to accelerate SQLite database operations by around 4 times for a given benchmark. The hardware used was a Samsung Chromebook with an Exynos 5250 SoC featurig a dual core Cortex A15 processor and an ARM Mali T604 GPU. CPU compute is only possible on ARM Mali T6xx and greater, and won’t work on Mali 400 / 450 GPUs. Other GPU vendors such as Vivante and Imagination […]

MicroView is a Tiny Arduino Compatible Board with an OLED Display (Crowdfunding)

Last year, we’ve been presented with many small Arduino compatible boards such as MicroDuino, RFDuino, BLEDuino, Spark Core, Olimexino-Nano and more… All these boards have been own strength and connectivity options, but if you want to see what going on in your board, you’d either need to connect it to your computer, or connect some LEDs or an external display. Geek Ammo’s MicroView fixes that by providing an Arduino compatible board nicely combined with a built-in OLED display. This allows you to display stats, weather, play games, create wearable projects (watch, necklace), and all sort of other projects that may require a small display. MicroView specifications: MCU – Atmel ATmega328P @ 16 MHz with 32KB flash, 2 KB SRAM, and 1KB EEPROM Display – 64×48 OLED Display Digital I/O – 12 (of which 3 provide PWM output) Analog Input – 6 Operating Voltage: 5V Input Voltage: 3.3VDC to 16VDC, no […]

Huawei D01 Server Board Features 16 ARM Cortex A15 Cores with up to 64 GB RAM, 3 SATA, 2 GbE Ports

During Linaro 14.02 release, I noticed a Huawei D01 board with 16 ARM Cortex A15 core, but details were lacking. Charbax was a Linaro Connect Asia earlier this month, and he could film the board in action, and interview the development team about this server board, and software development. Huawei D01 specifications: Processor HiSilicon SoC with16 x ARM Cortex-A15 CPU Core @ max. 1.5GHz (up to 84000 DMIPS) Support for CPU configuration as AMP/SMP Configurable Big or Little endian. Default: Little endian System Memory – 2x 64bit DDR3 DRAM Dual Inline Memory up to 1600 MHz, Module(DIMM) sockets:(2)&(3) . Default capacity: 8GB, upgradeable to 64GB Storage – 2x 1Gb NOR Flash, 2x 512MB NAND Flash, 3x SATA III for 2.5″ hard drives or SSD, 1x SD card Connectivity – 2x 10/100/1000Mbit/s Gigabit Ethernet ports, 1x 10/100Mbit/s FE port Other Peripheral Interfaces 2x USB 2.0 Host ports 2x UART, 4x I2C, […]

Mi World PCS is a Portable ARM mini PC with the Specifications of an High-end Smartphone (Crowdfunding)

Most ARM based mini PCs sell because they are cheap, low power and come in a small form factor. At about $600, Mi World PCS (Portable Computer System) is not cheap, but thanks to its battery it’s fully portable, and it has specifications similar to the latest flagship smartphones with a Qualcomm Snapdragon 800 quad core processor, 2 GB RAM, wireless charging support, and more. Mi World PCS specifications: SoC – Qualcommon Snapdragon 800 (8074) quad core Krait processor up to 2.4 GHz with Adreno 330 GPU, Hexagon QDSP6 DSP System Memory – 2 GB DDR3 memory Storage – 64 to 512 GB hot swappable SD RAID storage Video Output – Micro-HDMI for output in displays up to 4k Connectivity – Wi-Fi (802.11 AC), Bluetooth 4.0, and GPS IZat location technology USB – USB 3.0 Battery – Capacity N/A, up to 30 hour battery life Dimensions – N/A Weight – […]

Selecting the Best Adobe Flash Player in Linux for x86 and ARM

I’ve had countless and recurrent crashes caused by Adobe flash plugin either in Firefox and Chromium, mainly while playing videos from YouTube or other online video services that still mostly use flash, instead of HTML5. Adobe flash death is certain, but up to now it has been soooo slow, so I doubt that thing will truly die any time soon, and unfortunately it will probably be with us for many years to come. To work around the issue, I started by enabling Youtube HTML5 player, and try to play embedded videos inside YouTube instead of the orignal website. I still had crashes from time to time, and this method did not help with other video services. So I decided to check out what I could do to fix the issue. When you go to http://www.adobe.com/software/flash/about/ you can check your flash version, and Adobe will also list the player version for […]

Mali-400 GPU Is Now Working in Linux for Rockchip RK3188 Devices

Accelerated 3D graphics in Linux with Mali-400 via OpenGL ES has been possible for nearly a year on RK3066 devices, but there was no such support for RK3188. This week however, both Naoki FUKAUMI and omegamoon have reported OpenGL ES to work in in their respective RK3188 devices. I don’t know which device omegamoon used, but Naoki did so in Radxa Rock, and even posted instructions to build it yourself. They’ve mostly followed the work done by olegk0 for Rockchip, and Mali drivers build instructions provided in linux-sunxi community, and it can be summarize in 3 main steps: Cross-compile drm.ko, mali_drm.ko, ump.ko, mali.ko in a Linux machine Copy and load the four modules to your RK3188 based board or device. Install dependencies and binary Mali drivers from sunxi-linux in your Rockchip device Once this is done you can try some OpenGL ES demos such as esgears2 or glmark2-es to test […]

Mediatek MT6589 Linux Source Code, CyanogenMod 11 Image for Wiko Stairway Smartphone

Mediatek and their customers have still not gotten into the habit of complying with the GPL license, and releasing the relevant source code such as the Linux kernel. There appears to be at least one smartphone, Wiko Stairway, where the Linux kernel has been released, and chrmhoffmann, a members of XDA developers forums, has even released on unofficial CyanogenMod 11 ROM (Android 4.4.2 Kit Kat) for the device. There are three source repositories for the Linux kernel, “android device“, and Android. I’ve only looked into the kernel which is version 3.4.5. Mediatek has apparently messed up the Linux kernel quite a bit, and you’ll have to do some funny things to build the kernel, and all Mediatek options in menuconfig are in a sub-section called “Mediatek Properitary Configuration” (sic.), and it’s not possible to simply go to System Type menu to change the processor type for instance. Let’s get the […]
