This paper highlights the new architectural features and performance of the AMD OpteronT 6100 Series processor based HP ProLiant G7 Servers. It focuses on the value to the end user when applied to High Performance Computing (HPC) solutions.

What Is CFA and Why Do I Need It? This five-part paper series examines the conditions that led to the development of recommended rules, and describes the process by which automated design analysis and rule verification can help designers optimize designs to the fullest and most efficient use of area, while still ensuring manufacturability.

This paper will examine the implementation and demonstrate the benefits of eqDRC through a variety of examples comparing traditional DRC with eqDRC approaches.

The former "green" theme energy efficiency has become a household issue in an energy conscious society. The old filament bulb is disappearing step by step, washing machines and dish washers have become unsalable without energy saving programs. Still, most industrialized societies waste energy on a massive scale by indulging in comfortable "standby mode" in domestic electronics.

Viable distribution of Multi-channel Audio-over-IP for Live and Interactive "Voice Talent" based Gaming using High-quality, Low-latency Audio Codec technology.

"As the number of enhancements to various Hardware Description Languages (HDLs) has increased over the past year, so too has the complexity of determining which language is best for a particular design. Many designers and organizations are contemplating whether they should switch from one HDL to another. This paper compares the technical characteristics of three, general-purpose HDLs.

This white paper discusses the many factors that affect the choice of the best EMI shielding materials for an application. These factors include: the materials used in the product's enclosure, the environment in which the product will be used, performance requirements for the shielding materials, quantity of products to be manufactured, and the preferred installation equipment.

In the past, maintaining data separation in classified environments required the complete duplication of systems, including keyboard, video and mouse (KVM). Secure KVM switches eliminate this impractical desktop congestion by allowing users to quickly and easily switch between classified and unclassified systems with one set of KVM devices.

This paper provides recommendations and tips for accomplishing this by discussing: considerations for the wiring closet, identification of all network requirements, trends and tools for planning the placement of Access Points, decision factors to consider for combined networks, technology trends and standards, power level requirements, cable deployment and many other factors that impact the optimization of performance and reliability of combine wired and wireless networks.  Learn more today!

A powerful signal integrity analysis tool must be flexibility, easy to use and integrated into an existing EDA framework and design flow. In addition, it is important for the tool to be accurate enough. This report reviews a validation study for the Mentor Graphics HyperLynx 8.0 PI tool to establish confidence in using it for power integrity analysis.

For advanced signaling over high-loss channels, designs today are using equalization and several new measurement methods to evaluate the performance of the link. Both simulation and measurement tools support equalization and the new measurement methods, but correlation of results throughout the design flow is unclear. In this paper a high performance equalizing serial data link is measured and the performance is compared to that predicted by simulation. Then, the differences between simulation and measurements are discussed as well as methods to correlate the two.

High Density Interconnect (HDI) is being used more often to meet the growing need for more complex designs in smaller form factors. Beyond some of the more obvious electrical effects of using smaller vias, there is also an impact to the power integrity of a board using HDI. This includes different effects of mounted inductances of decoupling capacitors, changes in plane performance due to reduction in perforation from chip pinouts, and the inherent plane-capacitance changes from using dielectrics of various thicknesses. This paper will examine and quantify these effects, using numerous design examples, including a large conventional through-hole design board that was reduced using HDI.

The success of any consumer electronic device depends to a large extent on the appeal of the user interface (UI) and how easy the device is to use. Studies show that good cosmetic design can encourage users to explore the full range of features and often engenders the perception that a product is easier to use. So if the benefits of a great looking, easy-to-use UI are so clear, why are so many products still falling short of customer expectations? The solution lies in taking a fresh new approach a consumer electronic device UI plays. By identifying common UI functionality and implementing it in a reusable and customizable way, we can make it far easier for embedded engineers to deliver visually engaging and easy-to-use consumer electronic products.
