Technologies and Techniques to Accelerate Embedded Development

I’ve recently attended a webinar entitled “Accelerate Your Next Embedded Development Project: Essential Tools and Techniques for Every Phase of Your Project Lifecycle” presented by Wind river and VDC Research. The two speakers were: Marc Brown, Wind River VP, Tools and Marketing Operation. Christopher Rommel, Senior Analyst at VDC Research. The webinar was composed of three sections: Industry Challenges. (Wind River) Embedded Development: Data and Trends. (VDC Research) New ways to accelerate development (Wind River) Industry challenges Marc describes the new challenges for device software drivers: Increased security, safety and quality requirements for connectivity Performance scalability: multi-cores, many cores and SoC support. Pressure to lower OPEX (Operating Expenses) Companies are now pushed to increase performance, become more cost effective and provide a better connectivity while at the same time decrease time to market, project risks and security issues. Data and Trends Christopher first present a slide showing there are still […]

Embedded Hardware & Systems Trends for 2012 and Beyond

VDC Research currently has a research program called “STRATEGIC INSIGHTS 2012: EMBEDDED HARDWARE & SYSTEMS” where they analyze potential opportunities and give forecasts for embedded systems market through 2016. Some recent insights from their ongoing coverage of the Embedded Hardware & Systems market include: The Communications / Networking market is engaged in a period of dynamic change that is redefining the sector’s processing requirements. FPGAs & Linux are redefining embedded market growth requirements. The smart grid is creating new opportunities for embedded processors. Single board computers are enabling next-generation computing for military / aerospace applications. The Institute for Supply Management’s PMI index continues to demonstrate isolated pockets of regional growth, suggesting that new project starts and sustained unit shipments will maintain embedded market growth in 2012. The final reports should be available in 2012 as follows: TRACK 1: FASTFORWARD: INSIGHT FOR LEADERS Volume Number Volume Title Publication Date 1 Generating […]

Enable OpenGL 2.0 and WebGL for Intel GMA3150 in Ubuntu

I wanted to use WebGL in my Acer Aspire One D255E netbook that uses an Intel GMA 3150 onboard graphics card, but it did not work in Chromium nor Firefox. WebGL requires OpenGL 2.0 support, but I found out I only had support for OpenGL 1.4:

glxinfo | grep -i "OpenGL version"
OpenGL version string: 1.4 Mesa 7.7.1

1 2	glxinfo \| grep -i "OpenGL version" OpenGL version string: 1.4 Mesa 7.7.1

But I found out it was possible to enable OpenGL 2.0 for GMA 3150 in Linux by installing and running driconf:

sudo apt-get install driconf
driconf

1 2	sudo apt-get install driconf driconf

and clicking on “Enable limited ARB_fragment_shader support on 915/945.” and “Enable stub ARB_occlusion_query support on 915/945.” options. They are not enabled by default because they do cause problems. After those two options were enabled, OpenGL 2.0 was enabled.

glxinfo | grep -i "OpenGL version"
OpenGL version string: 2.0 Mesa 7.7.1

1 2	glxinfo \| grep -i "OpenGL version" OpenGL version string: 2.0 Mesa 7.7.1

But I still could not use WebGL in either Chromium nor Firefox, so I decided to install the latest version of Mesa (7.11) with indirect rendering (software) enabled with libOSMesa:

sudo apt-get install libffi-dev
wget ftp://ftp.freedesktop.org/pub/mesa/7.11/MesaLib-7.11.tar.bz2
tar xjvf MesaLib-7.11.tar.bz2
cd Mesa-7.11
./configure --enable-os-mesa --prefix=/usr
make
make install

sudo apt-get install libffi-dev

wget ftp://ftp.freedesktop.org/pub/mesa/7.11/MesaLib-7.11.tar.bz2

tar xjvf MesaLib-7.11.tar.bz2

cd Mesa-7.11

./configure --enable-os-mesa --prefix=/usr

make

make install

Even with the latest Mesa library, I could not use WebGL […]

OpenMAX (Open Media Acceleration)

OpenMAX (Open Media Acceleration) is a royalty-free, cross-platform set of C-language programming interfaces that provides abstractions for routines especially useful for audio, video, and still images. OpenMAX standard is managed by the non-profit technology consortium Khronos Group. OpenMAX allows developers to take advantages of hardware media decoding/encoding. For example, If you want to play video using Raspberry Pi hardware (VideoCore IV GPU in Broadcom BCM2835) you’ll have to use OpenMAX IL. OpenMAX provides three layers of interfaces: Application Layer (AL): Open standard for accelerating the capture, and presentation of audio, video, and images in multimedia applications on embedded and mobile devices. Integration Layer (IL) : API defining a standardized media component interface to enable developers and platform providers to integrate and communicate with multimedia codecs implemented in hardware or software. Development Layer (DL): APIs containing a comprehensive set of audio, video and imaging functions that can be implemented and optimized […]

Linaro’s Android Platform – ELCE 2011

Zach Pfeffer, Linaro Android Platform team leader, describes Linaro’s work on the Android platform and future plans at Embedded Linux Conference Europe 2011. Abstract: Linaro uses components from the Android Open Source Project, member companies, community supported efforts and Linaro engineering teams to build integrated, easy-to-use and well tested Android platforms for upstream work, product baselines and hobby projects. The team currently has platforms for TIs PandaBoard, BeagleBoard and Beagle xM, ST Ericsson’s Snowball, Samsung’s Origen and Freescale’s iMX53. They recently released platforms with Android 2.3.4 built against GCC 4.6 and running the 3.0 Linux kernel. In this session Zach reviews what’s been done, the Linaro Android concept, how Linaro brings Android together and what their plans are.

Device Tree Status Report – ELCE 2011

Grant Likely, owner at Secret Lab Technology, describe the current status of device tree (used to resolve ARM “hodgepodge” issue) and provides an example at Embedded Linux Conference Europe 2011. Abstract: In recent years, Linux has enjoyed immense success in the embedded market, and we’ve seen an explosion in the number of devices supported by the mainline Linux kernel. Traditionally, however, adding support for another embedded machine typically involved adding yet another board.c file to the kernel which more often than not was simply cut and paste from a similar board. As a result, board support code contains a huge amount of duplication and has become so huge that it is becoming unmaintainable. To move away from individual board files, several architectures have adopted the Device Tree method of encoding the hardware details into a data structure which can be parsed by generic initialization code and device drivers. This session […]
