Aikun CEO Rami talks about his latest Allwinner A33 Lollipop based 7.85" Grow series tablet with a sport design feeling and the Aikun-standard magnetic charger connector at the center of the back of the tablet. This is an interview filmed at the Aikun factory in Shenzhen China.
STMicroelectronics launches STM32 F7 series of very high performance Microcontroller Units based on the ARM Cortex-M7 core. The STM32 F7 devices are the world’s first ARM Cortex-M7 based 32-bit microcontrollers, improving on the benchmark performance. Taking advantage of ST’s ART Accelerator as well as an L1 cache, the STM32 F7 devices deliver the maximum theoretical performance of the Cortex-M7 no matter whether code is executed from embedded Flash or external Memory: 1000 CoreMark/428 DMIPS at 200 MHz fCPU.
Demonstrated running on the STM32 F7, IS2T MicroEJ SDK enables embedded Java development for any MCU and MPU, from the smallest ARM Cortex-M0+ to the newest Cortex-M7 and beyond. The embedded Java platform includes IS2T Java Virtual Machine (footprint: 28KB of RAM, 1.5KB of RAM) and IS2T libraries for IoT, GUI and communication applications. Boot time to first line of Java main is 2ms on a Cortex-M4@120MHz.
IoT solutions includes TPC/IP, Wifi, MQTT, Websockets, HTTP, JSON, XML, COAP... protocols. GUI solutions includes a full set of widgets, drawing, motions, anti-aliased... libraries - typical animations at 60FPS with less than 10% CPU load. Full Java applications run on MCU starting from 256KB of flash.
The MicroEJ demo running on STM32F7 device shows the Waddapps store connection, an online store of embedded applications that can be downloaded to the STM32F7 through any link (e.g. ethernet, Wifi, Bluetooth). Apps are downloaded, installed, started, stopped, uninstalled without reset - same as smartphone users would typically do with an Apps Store.
Freescale launches i.MX6SX for Heterogeneous Processing at Embedded World 2015, it has one ARM Cortex-A9 core running at 1Ghz and one ARM Cortex-M4 core running at 200Mhz. Enabling the Heterogeneous Processing on the new Freescale i.MX 6SoloX , Mentor Graphics shows their Mentor Embedded Multicore Framework that enables two capabilities necessary for taking advantage of mixed core architectures: 1) remote processor lifecycle management and 2) inter-processor communication. Remote processor lifecycle management is based on the open source standard remoteproc, and allows the master core to power and boot a remote core. The inter-processor communication mechanism is based on the open source standard rpmsg, and allows the establishment of a communication channel across different types of cores and operating systems.
The demo shown at the Freescale booth at Embedded World boots Mentor Embedded Linux on the A9 core. The Linux system runs a Qt based patient monitoring application. When the start button is pressed on the Qt application, remoteproc interfaces are used to power up the M4 core and launch the Nucleus RTOS firmware responsible for capturing patient data, then rpmsg interfaces are used to establish a VirtIO based communication mechanism between the applications across the mixed core and operating system architecture. Pressing the stop button on the Qt application the reverse happens, ending in a powered off M4 core.
The entire runtime software architecture is instrumented and the trace data is visualized in Sourcery Analyzer for simultaneous timeline performance analysis and debug of both operating systems and applications.
Tourists in San Francisco compare the top-3 brand high-end phablets in the world, among Huawei Mate7, Samsung Galaxy Note 4 and iPhone 6 Plus. Those are the flagship high-end mass market phablets of the moment from the top-3 Smartphone manufacturers in the world. This video highlights display size to body ratio, camera feature and large screen enjoyment. Come back for 2 more episodes to be posted on http://ARMdevices.net I think the Huawei Mate7 (which I have been using for the past 3 months) is the best phablet among those 3. Check back before MWC in the next 2-3 days for my review of my Huawei Mate7.
Seppo Takalo, Senior software engineer, talks about the work happening at the Thread group to enable secure and reliable Internet of Things, formed from companies who work with 802.15.4 based mesh networking components. The goal is to provide a standard for Secure, Robust, self healing, Native IPv6 based mesh networking that runs on top of 6LoWPAN and uses standard 802.15.4 radios.

Cavium is showing the most powerful ARM Processor in the world, with a 48-core ARMv8 64bit processor, demonstrating the high-performance visualization running the Xen Hypervisor running on an internal evaluation board and the KVM Hypervisor running on a rack-mounted 1U platform.
Greg Kroah-Hartman shows the Google Project Ara prototype phone and development board, and he talks about Greybus the protocol that they are developing to make it possible for these hardware modules that must be able to talk to each other and to the host module, they can be hot swappable, they have to be able to describe themselves so everything just works smoothly, they work on the knowledge that they have from USB, PCI, Firewire and all the previous protocols that people have implemented, they work on the base level of what UniPro can do, and they go from there. This is just another sub-system of Linux that drivers plug into. Rob Herring is the project tech lead at Linaro for Project Ara, and he talks about how the Linaro guys are working on the Kernel portions, the ARM Applications Processor modules and the Android modifications to support hardware modules hotplug in a Smartphone.
Smartphone hardware modules Google Project Ara is being shown by Linaro CEO George Grey, as the modifications to Linux on ARM to support Project Ara are being developed and optimized together with Linaro engineers, many of the Google Project Ara engineers meet at the Linaro Connect conference to advance their development for the project. Linaro is one of many companies working for Google on Project Ara, focused on the firmware and on the software to make Android work with removable modules, to communicate through the UniPro bus for hardware modules. Linaro has a lot of experts in Linux and the Linux kernel, able to deliver what Google needs for this project.
The Linaro ZTE Landing Team engineers talk about optimizing Android Kitkat boot time using TuxOnIce hibernation mechanism on ZTE SmartTV board. The net result is that it takes around 10 seconds to get into the Android home screen from a fresh power-on compared to the original over 30 seconds bootup time among other optimizations that they are doing for the ZTE Powered Set-top-box which is in millions of homes in China and around the world.
