Front Panel Hardware Considerations For ATCA, AMC, and MicroTCA Telecom Equipment

Acceptance of telecom industry standards for rack-mounted server equipment — in the form of the PCI Industrial Computer Manufacturer’s Group (PICMG) standards — is gaining momentum throughout global market channels. The objectives of those standards are certainly attractive in terms of streamlining economy and efficiency for both carriers and telecom equipment manufacturers across a number of areas. Their aim is to reduce development time and costs, as well as to help reduce the total cost of ownership. They are also intended to offer high levels of modularity and configurability while delivering high levels of service availability (99.999% and greater) and supporting appropriate scalability of system performance and capacity.

Getting Real-Time Performance From A Full-Featured OS

Spend a few minutes at your local electronics store and it's obvious — the mobile phone is a device that far surpasses its original intent. With respect to functionality, today's mobile phone goes well beyond the ability to make calls and store phone numbers. It also synchs up with your desktop's calendar and address book, it can take pictures, play and store music, and receive emails.

Omniscient Code Generation for 8-, 16- and 32-bit Microcontrollers

C-language programs are usually developed by teams of engineers who are often geographically dispersed, leading to redundant code and inconsistent variable declarations between modules. Traditional compilation technology compiles each module separately with no regard for what goes on in the other modules and with no information about how pointers, stacks, variables and functions are used throughout the whole program. Traditional compilers tend to over-allocate memory space for pointers, stacks and registers. They are unable to fully exploit the wide variety of memory maps, and register and stack configurations available in today’s micro-controllers. All too often, the programmer must resort to manual optimizations that compromise portability (Figure 1).

Using AdvancedTCA and MicroTCA in High-Availability Military Systems

The complexity of military and aerospace systems is growing — more components, interfaces, power, bandwidth, processing, features, and data — and these systems are being networked to form even more complex "systems of systems." Modern networkcentric systems can contain hundreds, even thousands of electronic modules.

Multipurpose Transaction Protocol: A New Data Transport Model

It is no secret that high-performance and the Internet are often seen as contradictory terms. Even private IP networks see serious performance challenges once they extend beyond the local building and around the globe. As devices and their users become more mobile, it has become critical to design with high-speed, Wide Area Networks in mind. But software and hardware designers are traditionally given few choices and little control for ensuring high network performance.

Wireless Electronic Patches Improve Medical Data and Patient Mobility

Non-invasive and ambulatory monitoring of body parameters is receiving much interest from the medical, sports and entertainment world. Possible applications are the monitoring of brain waves to detect epilepsy, monitoring of muscle activity during an athlete's training, and monitoring of heart rate during gaming. The idea is to develop small, low-power, autonomous biomedical monitoring systems that collect and process data from human body sensors and wirelessly transmit the data to a central monitoring system.

Techniques for Cooling Power and Other Electronic Devices

All electronic devices generate heat due to their unavoidable internal losses and inefficiencies. The higher the efficiency rating of the device, the less internal heat is generated within it. If we could achieve 100% efficiency, and technology is getting ever closer to that elusive goal, no heat would be generated within the device and, therefore, no cooling would be required. Until then, the generated heat must be dissipated to maximize the end product's reliability and prevent its premature failure.
