Nokia Qt Labs Releases Qt 5.0 Alpha

Nokia Qt Labs announced the alpha release of Qt 5 C++ application development framework, which focuses on the delivery of Qt Essential modules for Qt 5. This new version of Qt goal is to bring the focus to a model, although native Qt using C++ would still be used to implement modular backend functionality for Qt Quick. The developers explains that this module is working nicely on Qt for embedded system where UIs are full screen, but more work is needed on the desktop, and it will only be fully implemented in Qt 5.1 or 5.2. Qt developers make 4 big architectural changes to Qt internal architecture: Base all Qt ports on Qt Platform Abstraction layer (QPA) to make it easier to port Qt to other windowing systems and devices. Re-architect Qt graphics stack using a a Scenegraph on top of OpenGL to increase performance versus Qt 4, using Qt […]

ARM Development Studio 5 (DS 5) Demos At Design West

ARM has shot a few video demos of their ARM Development Studio 5 (DS 5), a software development tool suite for ARM platforms, at Design West 2012. The first video shows DS 5 running on the Xilinx Zynq-7000 platform (dual cortex A9 + FPGA), and we can see the memory map, registers, call graphs and stack usage. We can also see real-time processor switching and the function that takes the most CPU resources (profiling). The second videos showcases ARM DS-5 Streamline, a performance analyzer, which helps determine how well programs are running on a Linux or Android platform, on an Samsung Exynos 4210 platform (Origen board?). This tool also to profile both the dual-core ARM Cortex-A9 and ARM Mali-400 MP GPU in the platform. We are shown three types of reports: CPU/GPU Loading Threads usage Power Usage per application The third and last video shows ARM DS 5 on Freescale i.MX6 […]

Xilinx Zynq-7000 Extensible Processing Platform (EPP): Dual Cortex A9 + FPGA SoC

The Xilinx Zynq-7000 EPP (Extensible Processing Platform) is a new class of device, offering a mix of a dual-core ARM Cortex-A9 subsystem (including cache, memory controllers, interface, and peripheral functions) with a 28-nm programmable digital FPGA and programmable analog capabilities. This combination opens the door to a range of demanding applications, including automotive (video processing and analytics requirements for driver assistance systems), broadcast (high-bit-rate bandwidth for high-accuracy video processing and analytics), and industrial control systems that combine high-processing demands with tight integration requirements. There are actually 4 models which share the same processing subsystem (CPU core, memory, peripherals, etc…) and only differ by the programmable logic used: Z-7010 – Artix-7 FPGA with 28K logic cells. Z-7020 – Artix-7 FPGA with 85K logic cells. Z-7030 – Kintex-7 FPGA with 125K logic cells. Z-7045 – Kintex-7 FPGA with 350K logic cells. The Zynq-7000 EPP platform allows concurrent software and hardware development: System […]

TI SimpleLink GPS CC4000 Enables GPS For MCUs

Yesterday, Texas Instruments unveiled the SimpleLink GPS CC4000, a GPS self-contained module that can be interfaced with any MCU or MPU having a UART interface. Due to limited resources of microcontrollers, several GPS features have been implemented in hardware such as the push-to-fix function which can simply be controlled by the MCU via a GPIO to receive National Marena Electronics Association (NMEA) strings containing location, time and velocity information. TI Simplelink GPS CC4000 enables GPS-based applications such as asset tracking, industrial M2M, sports and fitness, and precision timing. It can deliver better than 2.5 meter accuracy and provides pulse-per-second output functions to provide precise location and timing data. It can also automatically reuse previously decoded satellite information thanks to its “watchful-eye” feature in order to deliver fast time to first fix (TTFF) and optimize power consumption. Here are SimpleLink GPS CC4000 key features: Driverless, fully integrated GPS solution which requires […]

FSLBOT: Freescale (Dancing) Robot Kit

Freescale unveiled the FSLBOT prototype last year (and I missed it!), and today, the company has announced further improvements to the Freescale Tower System mechatronics robot and board, a bipedal robot and development board that allows designers to write software for a variety of sensor applications while making a robot walk and respond to touch, motion, vibration, tilt and other external stimuli. The new version of the robot uses a new programming language based on StickOS, has wireless capabilities and adds an Xtrinsic MAG3110 magnetometer. This robot has been designed with the collaboration of StickOS and CPUStick.com with the goal “to create a tool that would enable casual users and consumers of technology to become creators and innovators”. The Freescale FSLBOT Robot Kit comes with the following: Freescale Tower System mechatronics board powered by a 32-bit ColdFire MCU with 64K of RAM and 512K of flash. Leg mechanics and associated […]

uClinux Running on Freescale Kinetis K70 MCU (Cortex-M4) Module

Last year, I posted about Linux for Cortex M3 & M4 Micro-controllers and noted it was difficult to find cost effective Cortex-M based boards able to run uClinux or Linux (RAM being the main issue). Freescale TWR-K70F120M is a module based on Kinetis K70 MCU (Cortex M-4) with plenty of RAM (128MB) to run Linux or uClinux. It is available for 109 USD or 179 USD with Freescale Tower system (TWR-K70F120M-KIT). Here are the key features of the module: Freescale MK70FN1M0VMJ12 Cortex-M4 MCU @ 120 MHz (Product Brief) Touch Tower Plug-in Socket General purpose Tower Plug-in (TWRPI) socket On-board JTAG debug circuit (OSJTAG) with virtual serial port 128 MB DDR2 SDRAM memory 256 MB SLC NAND flash memory Three axis accelerometer (MMA8451Q) Potentiometer Micro-SD Card slot I could not find an open source uClinux implementation for Kinetis K70, but emCraft has a Linux Board Support Package (BSP) for the Freescale TWR-K70F120M-KIT […]

A Novel Approach to In-Vehicle Infotainment (IVI) – Android Builder Summit 2012

Thomas B. Rücker, Program Manager at Tieto, discusses In-Vehicle Infotainment (IVI) with Android at the Android Builder Summit in February 2012. Abstract: In the future vehicles are going to be always online. The constantly increasing number of electronic devices raises consumer expectations. Both driver and passengers want to be online. This requires new and flexible IVI and HMI solutions. Users expect intuitive and simple to operate interfaces, but at the same time they expect the systems to handle a lot of their data and apps. We are witnessing a paradigm shift in Infotainment solutions. Open software platforms will allow users to add new functionality and services, also by third parties, over the whole life-span of a product. This requires solutions that reconcile the multi-media world of consumers with traffic security requirements, in a cost effective and secure hardware platform. The presentation will highlight challenges and opportunities by bringing Android to […]

Archos G10 xs Teaser Video with Sliding Keyboard Dock

Archos has just released a teaser video for its next generation Android tablet, the Archos G10 xs (xs stands for extra small). The video does not show much, except the concept of the new tablet which features a sliding keyboard where the tablet can be docked. Archos has not released the specifications for the G10 XS yet, but we do know the casing is made of stainless steel, is 7.6mm thick (12mm with the keyboard) and Archos has worked for 3 years on this design. There will be several models whose retail price should be between 200 and 300 Euros (Which would be between 200 and 300 USD in the US thanks to lower taxes). The new tablets will be powered by a Texas Instruments processor (probably OMAP 4) like the Archos G9 tablets and run Android 4.0 and Windows 8 depending on the model.
