Weightless Roadmap – Silicon, Modules, SDKs, Base Stations and Networks

The Weightless Standard aims at using the “white space” spectrum, previously used by analog TV broadcasts, for free M2M / IoT communication coupled with low power and cost-efficient hardware offering a range of over 10 km. Longer term the target is to reach $2 hardware cost, and $2 yearly servicing costs. Companies involved with Weightless include Neul, ARM, CSR and Freescale among others. You can read my previous post about Weightless for a longer overview. The Weightless Special Interest Group (SIG) has recently revealed the hardware roadmap for the new standard, which I’ll summarize below. Weightless Chip Neul Iceni, the first weightless silicon, was officially announced in February 2013. The latest version of the chip taped in May 2013 integrates UHF radio operating between 410 and 790 MHz supporting both TV white space and narrowband operation. It is suitable for low volume production applications. A third generation will be taped […]

ARM Based Servers and Servers-on-a-Chip (SoCs) at ARM Techcon 2013

ARM Techcon 2013 took place on October 29 – 31, 2013, in Santa Clara, and several companies announced servers, or chips for server based on ARM technology. None of those are for home used, but for now ARM based servers target enterprise and cloud data. Yet end users may them indirectly when they access social networks such as Facebook, or other online services such as Paypal. Calxeda ECX-2000 SoC After their ECX-1000 quad core Cortex A9 Server-on-chip, Calxeda has announced ECX-2000 SoC featuring four Cortex A15 cores. The new SoC provides about twice the performance, 3 times the memory bandwidth, and 4 times the memory capacity (up to 16GB RAM) of the earlier chip.   One of the key advantage of Cortex A15 over Cortex A9 is hardware virtualization that allows support for KVM and Xen hypervisors. ECX-2000 is supported in Canonical Ubuntu Linux 13.10 and can run Havana Openstack. Other […]

ARM Unveils Mali-T720 and Mali-T760 GPUs

ARM has recently announced two new Mali GPUs: Mali-T760 for high-end smartphones and tablets, and Mali-T720 for entry-level devices, but with better performance and energy performance compared to previous cost-optimized Mali GPUs, as well as OpenGL ES 3.0 support. These new GPUs have already been licensed by companies such as MediaTek, Rockchip, Samsung and LG Electronics.   Mali-T760 GPU ARM lists the key benefits and features of the ARM Mali-T760 GPU as follows: An increase in energy efficiency and performance of approximately 400 percent over the ARM       Mali-T604 GPU; Scaling to 16 shader cores, which doubles the previous generation, plus an increase in both performance per shader core and overall performance; Reduction of internal and SoC bandwidth utilization, significantly reducing energy consumption, enabled by ARM Frame Buffer Compression (AFBC), and Smart Composition, delivering more than 50 percent reduction in total memory bandwidth utilization; Simplified implementation through reduced wire count and […]

Embedded Linux Conference Europe 2013 Schedule – Build Systems, Security, Device Tree, Debugging & Profiling Techniques, and More

Embedded Linux Conference Europe 2013 will conveniently start right after LinuxCon 2013, last 2 days (October 23-24), and take place at the same location: the Edinburgh International Conference Center, Edinburgh, United Kingdom. The Linux Foundation has published the schedule for the conference, so I’ll make my own virtual schedule with sessions that I find particularly interesting. Thursday – 24th of October 9:30 – 10:10 – Timeline For Embedded Linux by Chris Simmonds, Consultant, 2net Limited Today, Linux is woven into the fabric of our technology. Things such as printers, routers, TVs and phones all have their own “Inner Penguin”. Yet it was never originally intended to be used beyond desktop and server PCs. A lot of things had to happen before Linux could break out of the PC environment and make its way in the world as a jobbing jack-of-all-trades. Since the early beginnings of embedded Linux in the late 1990’s many people have contributed […]

LinuxCon North America 2013 Schedule

LinuxCon (North America) 2013 will take place on September 16 – 18, 2013 in New Orleans, LA. The event will be co-located with several other conferences: the Linux Plumbers Conference, the Xen Project User Summit, the OpenDaylight Mini-Summit, the Gluster Workshop 2013, the UEFI Plugfest, the Linux Wireless Summit, the Linux Security Summit, and CloudOpen 2013. LinuxCon consists of 3 days of keynotes, and legal, operations, and developers related sessions as well as tutorials and workshops. There will be around 150 sessions and keynotes during those 3 days. I’ve gone through developer sessions and selected one for each time period. Monday, September 16 10:35 – 11:25 – UEFI and Linux by Kirk Bresniker, HP UEFI has become ubiquitous on the PC client systems and is coming up on servers and ARM-based systems, it is becoming the converged firmware infrastructure. UEFI Secure Boot feature has attracted a lot of attention from […]

ARM TechCon 2013 Schedule – ARM Servers, Internet of Things, Multicore, Hardware and Software Optimization and More

ARM Technology Conference (TechCon) 2013 will take place on October 29 – 31, 2013, in Santa Clara, and the detailed schedule for the event has just been made available. In the previous years, the conference was divided into  Chip Designs day (1 day), and the other 2 days were reserved for Software & System Design, but this year it does not appear to be the case. Whether you’ll be able to attend the event or not, it’s worth having a look at what will be discussed there in order to have a better understanding of what will be the key ARM developments in the near future in terms of hardware and software. There will be around 90 sessions categorized into 15 tracks: Accelerating Hardware Development – This track explores the resources, tools, and techniques that designers can employ to quickly bring hardware to market. Topics include multicore design, ARM IP, […]

Rockchip SoCs Comparison Table, RK32xx Quad Core Cortex A12 Coming Up in 2014

They guys at Linux Rockchip have setup a comparison table between Rockchip processors, but it’s not quite complete yet, and Rockchip noticed it, so they’ve just sent them the most recent Company Presentation that provides more details, including a roadmap. In this documentation, we can see the company targets different types of products with their SoCs: Android OTT dongle/box (aka mini PC, HDMI TV dongles…) – RK2928, RK3066, RK3068, and RK3188 Tablets – RK2926, RK2928, RK3028, RK3066, RK3168, and RK3188 EPD E-Book – RK2818, RK2906 and RK2918 MP3 player – RKnanoC On page 12 of the presentation, they have a convenient comparison table for the SoC used in mini PCs and Tablets.

big.LITTLE Processing Update – In-Kernel Switcher vs Global Task Scheduling

big.LITTLE processing is a new technology announced by ARM in 2011 that allows an SoC to feature low power cores (e.g. Cortex A7) together with high performance cores (e.g. Cortex A15) in order to optimize power consumption. I’ve previously detailed two big.LITTLE software implementation methods: In-kernel switcher which runs tasks on either Cortex A7 or Cortex A15 depending on the load, but both processors can not run simultaneously. Heterogeneous multiprocessing (now called Global Task Scheduling) that assigns tasks to relevant Cortex A7 or Cortex A15 cores, and if needed, allows all cores to run at the same time. Linaro has just provided a update for the big.LITTLE software implementation. There are currently only two SoCs that ship in products with Linaro b.L kernel support: ARM’s reference Test Chip 2 (TC2) tile for the Versatile Express development platform, configured as an SoC with 2 Cortex-A15 cores and 3 Cortex-A7 cores. Samsung-LSI’s […]
