Linaro Connect Europe 2013 Sessions and Mini-Summit

Linaro Connect Europe 2013 (LCE13) is taking place in Dublin, Ireland on July 8 – 12, 2013. If you are not there, you can still follow the event remotely as the event schedule is available with tracks focused on Android, Builds and Baselines, Enterprise, Graphics and Multimedia, Linux Kernel, Network, Project Management Tools and Training, and the Testing and Validation mini-summit will also take place at the same time. There will be hacking and lab sessions each day (except on Friday) where you can expect to learn useful skills. I’ve selected 2 sessions per day that I think might be particularly interesting. Monday 10:00 – 10:45 – ARMv8 Status and Updates Current Status of v8 tree What’s merged? What’s features are next priorities? Platform Updates What members should know about adding new v8 platforms 12:00 – 13:00 – How to make Android more efficient for entry level products The main objective of […]

AMD “Seattle” Server CPU to Pack up to 16 ARM Cortex A57 Cores

AMD has published a roadmap for the rest of 2013 and 2014 for its server processors, and among all the x86 “Jaguar”, “Warsaw” and “Streamroller” CPUs, there’s an “oddity” with the “Seatlle” processor featuring up to 16 ARM Cortex A57 cores using ARMv8 64-Bit architecture. “Seattle” will come with either 8- or 16-core CPU with ARM Cortex-A57 cores clocked at 2GHz or greater, and is expected to offer 2 to 4 times the performance of AMD Opteron X-Series processors (x86 APU SoC) with improvement in compute-per-watt. “Seatlle” will handle up to 128GB DRAM, use offload engines for better power efficiency and reduced CPU loading, provides server caliber encryption, compression and legacy networking including integrated 10GbE. “Seattle” samples are expected to be available in Q1 2014, with production in H2 2014. Via Liliputing Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a […]

Calxeda Showcases Aaeon and Foxconn ARM Servers at Computex 2013

ARM started to get involved in servers in 2011 with the announcements of Calxeda Energy Core, Marvell, and Applied Micro X-Gene Servers-on-a-Chip, and in 2012, products made by companies such as HP and Mitac started to appears. We’ve got to see some more ARM based servers this year thanks to Charbax, who filmed some Aaeon and Foxconn servers powered by Calxeda EnergyCore quad core ARM Cortex A9 SoC at Computex 2013. The first server is Aaeon Indus 1U cloud storage appliance: 1U Chassis 2x Calxeda Energycore nodes 10x 3.5″ HDD 2x 10 GbE uplinks and 4x 10GbE chassis-to-chassis interconnects Foxconn server shown at Computex has slightly higher specs: 4U chassis 12 Calxeda Energycore nodes 60x 3.5″ HDD for up to 240TB storage 4x 10 GbE uplinks and 6x 10 GbE chassis-to-chassis interconnects for 100 GbE total bandwidth There’s also a Gigabyte server, but I could get details. Server based on […]

ARM Announces Cortex-A12 processor, Mali-T622 GPU and Mali-V500 VPU

Right before Computer 2013, ARM has made a single announcement for 4 new products for smartphones: Cortex A12 core, Mali-T622 GPU, Mali-V500 video processor unit, and POP IP technology. Cortex A12 processor, with 40 percent more performance than Cortex-A9, positions itself between Cortex A9 and A15 offerings, and brings virtualization, big.LITTLE processing, and up to 1TB addressable memory to mid-range devices. Combined with the new Mali-T622 GPU, it will offer GPU Compute and OpenGL 3.0 solution. Add the new Mali-V500 video IP solution to complete the SoC for tomorrow’s, 2015 more exactly, mid-range smartphones and tablets between $200 and $350. Cortex A12 will have the following key features: Architecture – ARMv7-A Cortex Multicore – 1-4X SMP within a single processor cluster Multiple coherent processor clusters through AMBA 4 technology Support ARM Thumb-2 TrustZone security technology NEON Advanced SIMD DSP & SIMD extensions VFPv4 Floating point Hardware virtualization support Large Physical […]

2013 Embedded Market Study – Software Development & Processors

UBM releases a study of the embedded market every year, by surveying over 1,000 embedded professional every year. They’ve just published their 2013 Embedded Market Study (85 pages report), after surveying over 2,000 engineers and managers, so let’s see whether anything has evolved in the software development and processor space compared to 2012. Again this year, most respondents are based in the US (62%), followed by Europe (20%), and Asia (12%). C/C++ languages still rule the embedded world with 81% market share, although a little less than last year (85%), assembler is a distant third (5%). Interestingly, the average size of development teams seems to have shrunk from 15.9 in 2012 to 14.6 in 2013, the average project being composed of 4 software engineers, 2.9 hardware engineers, 2.7 firmware engineers, 2 QA/Test engineers, 1.5 system integrators, and 1.5 with other functions. About a third of project last less than 6 […]

Linaro Releases IKS big.LITTLE Implementation Source Code

Yesterday, Linaro announced the released of the IKS (In-kernel switcher) implementation for big.LITTLE processor which allows the SoC to switch between individual Cortex A7 or Cortex A15 cores to optimize power consumption. Currently, the only consumer device using supporting big.LITTLE the Samsung Galaxy S4 thanks to Samsung Exynos 5 Octa featuring 4 ARM Cortex A7 and 4 ARM Cortex A15 cores. IKS implementation can only make use of 4 cores at a time in this processor, since it must choose between A7 or A15 depending on the load. HMP (Heteregenous Multi-Processing) implementation is currently worked on in order to be able to use all 8 cores, and distributes tasks to the right core for the job. You can read my previous post for differences between IKS and HMP. Linaro explains the current source still needs a few more modifications before being upstream to mainline. The code was developed for and […]

Linux 3.9 Release

Linus Torvalds has announced the release of Linux Kernel 3.9: So the last week was much quieter than the preceding ones, which makes me suspect that one reason -rc7 was bigger than I liked was that people were gaming the system and had timed some of their pull requests for just before the release, explaining why -rc7 was big enough that I didn’t actually want to do a final release last week. Please don’t do that. Anyway. Whatever the reason, this week has been very quiet, which makes me much more comfortable doing the final 3.9 release, so I guess the last -rc8 ended up working. Because not only aren’t there very many commits here, even the ones that made it really are tiny and not pretty obscure and not very interesting. Also, this obviously means that the merge window is open. I won’t be merging anything today, but if […]

Using ARM Development Studio 5 (DS-5) Streamline with MK802II mini PC

MK802-II is an Android 4.0 mini PC powered by AllWinner A10 (ARM Cortex A8) with 1GB RAM and 4GB flash. Instructions are also available to run Ubuntu, or other Linux distributions. ARM Development Studio 5 (ARM DS-5) is software development tool suite for ARM processors that can be used for both Linux and Android debugging, and available in 2 versions: professional edition and community edition, the latter being free of charge. I’m writing about both today, because Bob Peng, Technical Marking Engineer for ARM China, recently wrote a blog post in Chinese [Update: An English version is now available] showing how to use MK802-II, preloaded with the required drivers and daemon, with DS-5 Streamline Performance Analyzer with is part of both versions. The community edition may be missing some features of Streamline however. Streamline Performance Analyzer allows you to: Find out which modules or functions to take up most of […]
