ARM Unveils Server Base System Architecture Specification (SBSA) to Standardize ARM based Servers

64-bit ARM based servers should hit the market later this year or earlier in 2015 with SoCs such as Applied Micro X-Gene or AMD Opteron A1100. ARM still has the lead in terms of efficiency with a lower dollar per watt ratio, but Intel is closing in with their new Avoton server-on-chips. However, there’s one aspect where Intel is clearly in the lead: standardization and compatibility. ARM is very flexible, and allow SoC designers to create more or less what they want, but it comes at the cost that most ARM based systems are not capable of running mainline Linux, and instead use vendor trees. With many applications, that may not be critical, but when it comes to data-centers, companies want to be able to run the latest Linux version with the latest security patches as soon as possible, and want to lower the total cost of ownership (TCO), so […]

ARM Unveils Cortex-M Prototyping System Based on Altera Cyclone V FPGA

Before micro-controllers or processors are manufactured, simulation is performed in (usually) expensive boards based on FPGA chips from Altera or Xilinx, and once designers have found the system to work as expected, they can move to the next phase and work on the actual silicon. ARM has just released V2M-MPS2 Cortex-M Prototyping System for MCU / SoC / ASIC designers working on Cortex-M processors. Key features: Altera Cyclone V FPGA with ~150K LE 4x 2MB ZBTRAM (32-bit each, with two of them forming a 64-bit memory). ZBT = Zero Bus Latency 16MB PSRAM (16-bit) Touch screen LCD module Range of hardware interfaces – UART, VGA (4 bit per color), SPI, audio (I2S), Ethernet, LEDs, buttons I/O expansion ports (GPIO) FPGA images for Cortex-M processors Example project for Cortex-M0 DesignStart (processor IP has to be licensed separately) USB connection for downloading FPGA images and program image to micro SD card on board […]

ARM Mali GPU Demos at CES 2014 – 4K 3D UI and Games, ASTC Texture Compression, XBMC + Gesture Recognition, and HEVC Video Decoding

Phill Smith, Demo Manager at ARM, has filmed and uploaded four very interesting demos of what new features will be possible thanks to new generation ARM Mali-450 and Mali-T6xx GPUs including 4K 3D user interfaces and games, ASTC texture compression, and OpenCL accelerated gesture recognition and HEVC / H.265 video decoding. 4K Resolution 3D User Interface and Game Demo The first demo showcases a Geniatech box (ATV1800?) powered by AMLogic AML8726-M8 featuring an ARM Mali-450MP6 GPU running Android with a user 4K 3D interface designed by Autodesk using Scaleform UI. The rest of the video shows Timbuku 3D gaming demo running at 3840×2160 (4K2K) @ 24 fps. The frame rate appears to be low, but that’s because the box is using HDMI 1.4, which limits UHD output to 24fps. 2160p60 is only available via HDMI 2.0. ASTC Compression Demo on Samsung Galaxy Note 3 3D Textures are getting bigger and […]

NVidia Announces Tegra K1 32-bit & 64-bit SoCs with a 192 Core Kepler GPU

Nvidia announced their newest mobile SoC at CES 2014, but instead of calling it Tegra 5, they went for Tegra K1, as it’s the first to feature a 192 cores GPU based on Kepler architecture, the same as used in PC graphics card. There will be several version of the chip one based on four Cortex A15 cores, one featuring a dual core Nvidia Denver CPU based on ARMv8 64-bit architecture, and Tegra K1 VCM for the automotive market. The company showcased the power of their new processor with an Unreal Engine 4 demo and the same face demo showed last year on an Nvidia GPU card, and Tegra K1 easily outperform older generations games console such as Xbox 360 and PlayStation 3, at and the same time consume just about 5 Watts of power, versus 100 Watts for Microsoft and Sony consoles. The GPU in the Tegra K1 also […]

Bodhi Linux Distribution Has Dropped Official ARM Support (For a While)

Linux is omnipresent in your life via gadget running Android, but in the desktop world, as many of you already know, it’s not straightforward to get a Linux distribution fully work on ARM platform, because each ARM SoC or board is different, and above all binary blobs used for GPUs, VPUs, Wi-Fi and Bluetooth chips can make it extremely complex, even impossible, to have a fully working ARM Linux distribution for a given hardware. After considering that ARM Linux required too much effort, and was not used by many people, Bodhi Linux developers decided to call it a day in October this year, and dropped official support for ARM hard-float images: Effective immediately Bodhi is dropping official support for ARM devices. What does this mean? We will no longer be advertising an ARMHF download link on our front page Updates to ARM images will be infrequent/not at all. The ARM […]
