Critical movements for German embedded computer users


German based Lauterbach is recognised for both engineering excellence and exceptional technical support. The quality and capability of Lauterbach tools enable engineers to develop robust code whilst minimising development time lost to debugging. They have become a favourite with many hi-tech engineers, supporting more than 3500 embedded computers and all known ARM Cores; covering products from over 75 embedded computers companies.

Engineers working in the development of software for automotive embedded computers will have the opportunity to learn about the latest tools and techniques at Lauterbach's September Automotive Forum.

Much of the content will be based around the embedded computers development and validation of Autosar compliant code and the development of code for specific devices such as the BOSCH GTM, the AURIX and Freescale's Nexus based Qorivva solutions. Some of the presentations will also touch on the debugging of code on multicore systems. Delegates will also have the opportunity to discuss their specific challenges and requirements.

Samples for embedded telehealth inventions



This is just one example of why embedded computer telehealth strategies are poised to revolutionize medicine. Telehealth not only provides quick access to specialists, but can also remotely monitor patients and reduce clinical expenses. Many of the systems needed to realize these benefits will operate on the edge, and require technology with the portability and price point of commercial mobile platforms, as well as the flexibility to perform multiple functions securely and in real time. All of this must be provided in a embedded computer package that can meet the rigors of certification and scale over long lifecycle deployments.

The ability to transition between x86 and ARM processors is critical for low-volume medical applications because a single carrier board – often the most costly component of a COM architecture – embedded computer can suit the needs of both graphics-intensive systems and platforms that require more mobility and lower power. In addition to reducing Time-To-Market (TTM), this decreases Bill Of Materials (BOM) costs and eases Board Support Package (BSP) implementation, says Christoph Budelmann, General Manager, Budelmann Elektronik GmbH in Münster, Germany (www.budelmann-elektronik.com).

Applications of FPGA versus embedded system



The use of FPGAs for the I/O embedded system implementation may be more difficult than using a dedicated controller. On the other hand, an implementation in a programmable device has multiple advantages. FPGAs are intended for embedded applications, with a long support lifecycle, a wide temperature range, and the option to move the IP to a more recent device when needed. In addition, using a soft IP, the interface can be improved and new embedded system features can be added. A simple end-point interface can be upgraded to a test resource by adding more extensive error detection and injection capabilities.

CES has long used FPGAs for I/O customization and to implement test devices. The new CES FIOV-2310 product is a 3U VPX board with a Kintex-7 FPGA and an FMC slot (Figure 2). A wide range of FMC mezzanines are available from partners and from independent vendors, both for signal processing and I/O customization applications.

One size fits all - Your all-rounded embedded computer scheme.



Using Ethernet as an integrated embedded computer processor interconnect requires significant transaction acceleration and solutions to the Ethernet Media Access Controller (MAC) as well as the Ethernet switch devices themselves. Even with these enhancements, RDMA operations should be limited to large block transactions to amortize the overhead of using Ethernet.
Standards that have been deployed to solve this problem include the iWARP RDMA protocol from the Internet Engineering Task Force and RDMA over Converged Ethernet (RoCE). Both iWARP and RoCE are typically implemented through acceleration coprocessors. Despite this acceleration, RDMA transactions must still be carefully managed to reduce communications overhead. The reason is that although Ethernet offers high bandwidth, especially in  and 40 GbE implementations, it also has high transaction embedded computer  tencies that are typically measured in microseconds.

Embedded computer life cycle


After a embedded computer's life-cycle analysis and the “sticker shock” associated with the cost of a commercial OS, designers usually also consider “free” open source operating systems. Although open source software eliminates some initial cost problems, there are still significant issues that must be addressed. One problem voiced by potential open source users is the lack of a central embedded computer resource to provide support similar to a commercial software vendor. Developers can often find answers to their questions through the Internet, but no one is on the hook to research and respond to a specific question. Open source products are generalized in order to fit the widest array of users and can force designers to modify the hardware configuration, resulting in higher recurring cost for the embedded device.
