VITA 49: Software radio's evolving language
Overwhelming adoption of software radio as a critical technology for real-time embedded systems spurs defense customers to expand its capabilities for the constantly evolving needs of military applications. With numerous vendors in the market, customers are seeking interoperability and easy insertion of new technology. However, data protocols, metadata information, and control software have traditionally been vendor-unique, proprietary solutions, capable of meeting the requirements of any given system, but highly variable, even when delivered by the same vendor. To overcome these inconsistencies, VITA 49 offers standards for implementing these features to boost user confidence in multivendor, open architecture systems, and simplify life cycle support.

Critical Techniques for High Speed A/D Converters in Real-Time Systems
Markets for high-speed A/D converters are significant in size and many are growing rapidly. Commercial users include wireless mobile communication systems, airline radar, air traffic control towers, ship communications, and wireless networks. Industrial uses include medical imaging systems and process control systems. Government is another significant user: military radar, global military radio networks, unmanned aerial vehicles, and intelligence gathering systems.

High-Speed Switched Serial Fabrics Improve System Design, Third Edition
When VXS, a proposal for standardizing gigabit serial switched fabrics shook the embedded community in 2002 as part of the VMEbus renaissance, XMC, a natural extension of that technology to PMC modules was inevitable. VXS is the popular name for a switched serial backplane fabric implementation for VMEbus. The VXS specification is fabric-transparent, in that there are subspecifications, one for each of fabrics: Infiniband, Serial RapidIO, Gigabit Ethernet, PCI Express.
