Adapting to the extremes of rugged design

Ruggedisation and reliability are key requirements for a wide range of embedded computing markets, including industrial, medical, airplane or railway applications. Reliable operation is particularly important for safety-critical applications such as avionics and railway control. To meet the needs of these markets, embedded developers must carefully consider issues including hardware selection, manufacturing and testing methodologies, and software design. In this article we will explore these areas and show how embedded developers can build rugged systems with minimal cost and effort.

The impact of digital oscilloscope blind time on your measurements

All digital oscilloscopes are temporarily blind. During this blind time the user will miss critical signal events at his device under test. Thus, it is necessary to understand the impact of blind time to the measurement. This application note explains the background of blind time and points out why a high acquisition rate is important. It furthermore explains the R&S RTO oscilloscope capabilities and how they help for faster debugging, measurement and analysis.

MontaVista Linux Carrier Grade Edition

Communications networks are very different from other kinds of computing applications. Networks require both very high reliability and very high performance. Not only must they process large volumes of data at high speed, but they must do so while limiting their downtime to minutes per year. Network failures can have huge economic consequences and can even result in the loss of life. Additionally, in this post-9/11 world, failure also has a national security dimension. This technical whitepaper introduces MontaVista Linux Carrier Grade Edition — what it is, how it evolved, and how it provides a foundation for developing and deploying carrier-grade applications like those described above.

Using vfAnalyst to Understand Program Behaviour

This whitepaper from Vector Fabrics describes the relationships and dependencies that exist, and will highlight them in the context of a new analysis tool called vfAnalyst that can be used to understand the behaviour of a program.

Redundant MicroTCA power systems

The demanding requirements put forth by redundant operation for both payload and management power can be met and interoperability between the power modules and the MicroTCA carrier hub achieved using MicroTCA compliant products.

Digital techniques in power conversion

The concept of "digital power" has received significant attention and promotion in the past few years, from both semiconductor suppliers and power supply manufacturers. There is a need to explain the concepts of digital power; explore the advantages and tradeoffs of digital techniques compared to analogue approaches; discuss some of the standardisation directions; and explore the possibilities for digital power.

Is digital power moving forward?

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the power industry have been around in the marketplace. At a time when energy efficiency and power consumption are becoming more strategic than ever, the debate around how "digital power" will change the face of the world has never been so intense. Energised by the high marketing buzz surrounding 'the new power revolution', thousand of papers have often strongly expressed the details and benefits of implementing such technology. However, a certain market perception gives the feeling that behind the noise generated by the media, digital power seems not to have moved as fast as expected. Wrong perception or reality?

From digital confusion to digital conversion

It is now several years since commercial products with 'added digital performance' aiming to revolutionise the on-board power industry have been around in the marketplace. The debate around how such products will change the face of the world has never been so intense, resulting in a certain kind of confusion.

Digital DC/DC converter family integrates PMBUS connectivity

Able to work with any type of power converter, PMBus is a major success story. Its simple SMBus-based two-wire hardware interface is similar to and generally compatible with I2C, while the improved signaling protocols assure greater robustness. As a result, system designers can easily implement power management strategies that range from voltage sequencing or multi-voltage logic devices to monitoring and controlling entire systems using a uniform approach that has minimal impact upon resources.

Digital DC/DC converter benefits in MicroTCA power modules

Micro Telecommunications Computing Architecture (MicroTCA) is a relatively new architectural specification for Information and Communications Technology (ICT) and industrial equipment intended for relatively small, low power applications where it can be more cost effective than other architectures. The key power assembly in MicroTCA is called the 'MicroTCA power module' , which, by its own definition has to deliver and secure the power required by Advanced Mezzanine Cards and other accessories that plug-into the MicroTCA enclosure.

Batteries worldwide celebrate the arrival of the world's most energy friendly microcontrollers

The explosion in use of battery operated electronics is followed by the need for the battery to last longer for convenience, environmental and cost reasons. At the same time, applications become more and more complex and demand higher performance of the microcontroller, making the challenge of designing systems for low power even more difficult. This white paper looks at Energy Micro's EFM32 microcontroller family, which it says has an energy consumption many times lower than any other microcontroller family today, whether you benchmark with leading 8, 16 or 32 bit microcontrollers.

Network Technology for Embedded Computing

Networks are gaining importance in all disciplines of embedded computing: At the high-end, multi-processor systems need high-speed networks for interconnectivity and feeding in data. The scope of this paper are major trends in Ethernet network technology and how network technology, both hardware and software, is implemented in high-end embedded systems. As practical examples, embedded form factors CompactPCI and MicroTCA are shown at 10 Gigabit/s speed for switching and packet processing. This paper concludes with a practical look into the components of a switching platform for embedded products.

3E-Enhanced performance, Energy management and increased End-user value with digital POL regulators

Ericsson Power Modules' new digital POL (point-of-load) regulators establish an innovative approach to reach the goals of end-user value, flexibility and system performance. These new power supply products contain several unique concepts and features spanning the disciplines of mechanical packaging, electrical design, control loop algorithms, power system architecture, power and energy management tools and logistics during system manufacturing and field support.
