How VPX is helping build tomorrow’s interoperable military systems
The objectives of the Modular Open Systems Approach (MOSA)—to improve system capabilities, compatibility and cost—are predicated on a tight collaboration between government and industry. Although each service branch of the military has a model or view of what they need in their standards to produce the systems they require, a common goal of interoperability has reshaped the military electronics landscape over these past few years.

Serial switched fabrics - Got you covered
Ethernet, PCI Express, Serial RapidIO, and Infiniband fabrics are all being aggressively enhanced. There are still, however, serious roadmap considerations when selecting one to dress your high-performance embedded system.

"Critical embedded systems" defined
Exactly what is a "critical system," how do we define it, and does it makes a difference if we do?

Unmanned vehicles overcome video challenges
Choosing an appropriate video codec is fundamental to achieving optimal success in a UAV-based mission. JPEG2000 and H.264 offer designers two alternatives, each with advantages and disadvantages.

ANSI/VITA 65 - The ins and outs of OpenVPX chassis selection
The recently ratified ANSI/VITA 65 (OpenVPX) standard includes recommended profiles for development chassis including key areas such as power supply outputs and chassis cooling. Together with a variety of standard OpenVPX backplane profiles, this enables chassis vendors to offer standard development chassis that better match the needs of subsystem developers. Bob explores the criteria for development chassis selection and OpenVPX-compliant cooling, power profiles, and backplanes. Serial fabric protocols and OpenVPX chassis deployment are also examined.

Harnessing the promise of 3D data in real-time critical applications
A robust 3D SDK and engine that seeks to make 3D accessible for rapid application development provides an excellent place to start harnessing technologies such as GPU computing, data compression, and remote data access into a single technology platform.

Upgraded approaches for "safe" and "reliable" COTS designs
Although commonly confused, “safe” and “reliable” are not synonymous in mission-critical applications, as designers often need embedded systems to function at different levels of “safe” while remaining consistently reliable.

Case study: Using VME to build an FPGA-based data acquisition system
While many have turned away from VME in favor of VXS, VPX, and even PC-based “computer motherboard” modules, among other iterations, this case study shows that VME is still a viable candidate in FPGA-based data acquisition systems. The primary reasons: Its high pin counts and additional P0 connector – plusses that came in handy when Joerger Enterprises designed its new module’s basecards and daughtercards.
