AMD To Provide 64-Bit ARM Opteron Processors for the Server Market

AMD announced it will design processors based on 64-bit ARM technology in addition to its x86 processors for the cloud and data center servers. AMD will be the first company to provide both x86 and ARM solutions to the server market, and the first ARM-based server CPU is scheduled for 2014. There aren’t much details at this time, but AMD did say it will be take advantage of AMD SeaMicro Freedom supercompute fabric in order to link CPU, Ethernet and Storage and the processor will be sold as an AMD Opteron CPU. Interestingly, the company does not plan to design 64-bit ARM processor for the client market (e.g. Windows RT) for the time being. Red Hat and AMD partnered for the server software, and Red Hat has started to work to bring support for the next generation of 64-bit ARM server processors to the Fedora Project include 64-bit ARM OpenJDK.

Oracle releases JDK for Linux ARM (Soft-Float Only)

Oracle announced the availability of JDK 7 Update 6 which introduces a JDK for Linux on ARM v6 and v7 architecture. This JDK is aimed at “general purpose” ARM systems, such as ARM micro-servers and ARM development platforms. This new JDK for Linux on ARM is licensed under the Oracle Binary Code License, and can be downloaded at no cost for development and production use on general-purpose platforms. For embedded use such as an industrial controller or a kiosk appliance, a commercial license would be required. Here’s how Oracle summarizes the ARM Linux JDK features: This port provides 32-bit binary for ARMv6 and v7, with full support for Swing/AWT, both client (C1) and server (C2) compilers and runs on most Linux distributions. One caveat is that the current binary is softfloat ABI only, so it won’t work with (for example) the Raspbian distribution which uses the hardfloat ABI. We are […]

ARM Demonstrates Mali-T604 GPU in Samsung Exynos 5 Dual Cortex A15 Processor

For the very first time, ARM showcased on of their latest GPU, the Mali T-604, at SIGGRAPH 2012. There were 3 demos running in a tablet reference platform based on Samsung Exynos 5 Dual Cortex A15 processor clocked at 1.7 GHz: Timbuktu 2 showing improvement brought by OpenGL ES 3.0 such as higher details buffers, shadow comparison, etc… Hauntheim showcasing multiple lightings accelerated with GLES 3.0 and OpenCL (GPU compute) Enlighten, a demo where you can adjust the sun position and see the building shadows move smoothly in real-time.

Rikomagic To Sell an AllWinner A10 Android & Ubuntu Netbook

Rikomagic, the company that sells the MK802 mini PC, is planning to sell a netbook based on AllWinner A10 processor that runs both Android and Ubuntu operating systems. This device looks very much like the H6 netbook with a 10″ 1024×600 display, 1 GB RAM, 4 to 8 GB flash. an SD card slot, 3 USD ports, audio in/out and a front camera. Android currently runs in the internal flash, and Ubuntu can be booted from an SD card. In the video below, Andy Kirby of Rikomagic gives an overview of the netbook and shows a demo of Ubuntu Desktop running from an SD card. The Linux OS seems to run relatively smoothly as he shows pages rendered in Chromium.However, hardware acceleration (both OpenGL and VE) is missing, and Youtube video playback is very slow as it is rendering in software. Open Office is also a bit slow, but it’s […]

15 Linaro OnAir Sessions about Android, Linux, Debugging and Software QA

Linaro has planned 15 virtual conferences between Monday, August 13 and Saturday, August 18, 2012. Those online events will deal with the work done at Linaro, including software optimization, software QA, Android and Linux kernel development, Open Embedded on ARMv8 and more. Those conferences are public and anybody can join. All times indicated below are GMT+07:00 (Bangkok), so you can either mentally convert the time (recommended), or click on the links below to get the date and time in your timezone. Exploring The Performance Impact of PGO and LTO on ARM– Mon, August 13, 5:00 PM Abstract: Profile guided and linked time optimisation (PGO and LTO) are two of GCC’s cross program optimisations that should improve both the startup and runtime of typical programs. We know that they basically work on ARM but don’t know the potential speed up or the work involved in proper support. This session will cover […]

ARM Announces 3 New Midgard GPUs – Mali-T624, Mali-T628 and Mali-T678

ARM announced the second generation of the Mali-T600 Series GPUs targeting tablets, smartphones and smart TVs. Those new GPUs provide up to 50% performance increase over the first generation Midgard GPUs (T-604 & T-658) and include support for Adaptive Scalable Texture Compression (ASTC), a texture compression technique. The company explains that ASTC significantly optimizes GPU performance and increases battery life in devices. Those 3 new GPUs based on Mali Midgard architecture are named as follows: Mali-T624 – 1 to 4 cores – Market: Smartphones and smart-Tvs Mali-T628 – 5 to 8 cores – Market: Smartphones and smart-Tvs Mali-T678 – Up to 8 cores, 4x the GPU compute performance of Mali-T628 – Market: Tablets As with previous Midgard GPUs, the new GPUs support GPU compute with improves performance and energy-efficiency for math intensive activities, such as: Computational photography – computational methods of enhancing or extending digital photography Multi perspective views – […]
