Linaro 12.03 Release with Kernel 3.3-rc3

Linaro has just released version 12.03 based on Linux Kernel 3.3-rc3 and Android 4.0.3. Among the key points, hardware video decode in now supported in Origen (Android),  Android runs in A15/A7 platforms, libav AAC optimization provides about 2x performance improvement and QEMU supports Samsung Exynos 4240 and Calxeda Highbank (work done upstream). Here are the highlights of the release: Android Linaro Android has support for DS-5 version 5.9. Hardware accelerated Multimedia is now integrated on Origen. EEMBC, denbench and coremark have been ported to Android and are running in LAVA. android.net ConnectivityManager unit tests have been built and integrated in all builds. Hardware decode of H264 and MPEG4, 1080P and 30 FPS is enabled on Origen. Origen now has 1080p HDMI Graphics and Video Support. Android runs on A15, A7 and A15/A7 fast models. ARM’s big.LITTLE has been tested running Android using a set of unit tests. Kernels of prebuilt […]

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 […]

ARM Releases Ne10: An Open Source Library with NEON Optimized Functions

Arm NE10

The Advanced SIMD extension (aka NEON or “MPE” Media Processing Engine) is a combined 64- and 128-bit single instruction multiple data (SIMD) instruction set that provides standardized acceleration for media and signal processing applications for ARM Cortex-A (ARMv7) processors and the goal of these instructions is similar to MMX, SSE, and 3DNow! extensions for x86 processors. Starting early 2011, ARM has been working internally on a project codenamed Snappy to develop common functions accelerated by NEON. They have now released the first version of Snappy, now called the Ne10 library, which is available on GitHub at https://github.com/projectNe10/Ne10 . The code has been developed in C and Assembler and tested on Ubuntu on ARM (Linaro). A Makefile is also included to build it for Android (AOSP). The current functions include vector and matrix operations accelerated by NEON instructions. Since the library is open source, ARM hopes developers will make use of the Ne10 […]

Virtual Hardware Platforms: Test & Debug Software Before the Silicon is Ready

Historically software could only be tested and debugged when the first silicon sample was ready, and the software team could not participate in the design process. But thanks to Virtual Hardware Platforms, software can be executed at speeds close to real time on an abstract model of the hardware, available long before a design has been completed. The virtual platform is designed to simplify the creation and support of virtual prototypes and allow design teams to begin developing software weeks to months before a hardware prototype is available, and software teams can use it as their application development platform. For example, Freescale is using a Virtual Hardware Platform for their new Vybrid Controllers to emulate both Cortex A5 and Cortex M4 cores, as well as peripherals and run OS such as Linux or MQX before the Controllers are ready (Q2 2012). One Virtual Hardware Platform has just won the ACE […]

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 […]

Cross-compiling the ARM Linux Kernel in Ubuntu 12.04 LTS

Yesterday I installed Ubuntu 12.04 ‘Precise’ Beta 1 in Virtual Box to give it a try (I could not manage to have HUD working btw), and today, I’ve noticed an article entitled “Ubuntu 12.04 ‘precise’ and cross compilation of ARM kernels” explaining how to build Linaro ARM kernel in Ubuntu 12.04. So I’ve decided to give it a try, especially it seems straightforward. I followed the instructions in the aforementioned link,  it basically worked except I had to install dpkg-dev package that also installed the build essentials (gcc, g++, etc…) and use sudo for some commands. You’ll notice the name change for the ARM gcc toolchain as it now uses hard-float by default which seems to provide quite a boost in performance for the Pandaboard. Here are the steps I followed: Install the ARM GCC cross compiler and the development package of dpkg:

Retrieve the kernel source:

Install […]

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.
