Over the years, VITA's charter has evolved to embrace a host of new open architecture standards for critical embedded computing. Originally founded to develop standards and an ecosystem in support of VMEbus, VITA has evolved its interconnect strategy for high performance computing to be based on leading switched fabrics. Most popular are Ethernet, PCI Express, InfiniBand, and Serial RapidIO. Today's working groups now spend their efforts on developing standards that implement the latest advancements in the roadmaps of these fabrics in various VITA form factors such as VPX, VNX, XMC, and FMC. The working groups are no longer responsible for defining the protocols but ensuring that the right connector technology is defined suitable for VITA form factors and ensuring that the correct connector technology is implemented as appropriate.

When one envisions a VPX system, the image that often comes to mind is a multislot high performance computing system full of processing and I/O boards. But there is a completely different class of VPX "systems" that range from one to three slots in size, primarily in a 3U form factor. What do these "systems" look like and what is driving their existence?

The new generation of VPX protocols are here and the next generations are on the horizon. The exciting world of high speed has arrived and before we know it today's technology will be superseded. VPX is "evolving." The next generation of PCIe and Ethernet will add more complexities to the VPX signal channel. We are seeing data rates increase exponentially and the evolution of VPX has begun.

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.

The concept of modular designs in small-form-factor (SFF) electronic systems poses interesting challenges to equipment suppliers who feed the embedded computing market's demand for smaller, more cost-effective solutions. Competing expectations from designers include reduced size, lower cost, lower NRE (nonrecurring engineering) charges, and the drive for the most forward-reaching future-proof designs that enable form, fit, and functional upgrades at a reasonable cost.

Since the announcement of VMEbus in 1981 there have been a great number of people and ideas that have had an impact on the development and advancement of open standards used in critical embedded computing systems. The intention of the VITA Technologies Hall of Fame is to honor and preserve the remembrance of those people and technologies that have had the greatest influence on the VITA open standards industry. Many others are to come - innovators and influencers, who have made a significant impact on developing, designing, creating the technology, and ferrying the technical specifications into open standards. These are the people who have overcome the technical and procedural problems, the products that set new expectations. It is our pleasure to honor these primary contributors to this industry.

In January, Embedded Tech Trends 2018 was held in Austin, Texas at the Hilton Garden Inn Downtown. Just off 6th Street, attendees had walking access to the famous Austin music scene and wonderful BBQ.

The VPX form factor is used today for a wide range of applications and deployed environments. Applications vary from rail management systems to active electronically scanned array (AESA) radars on high-performance fighter aircraft, and environments vary from lab-benign (or near-lab conditions like wide-body jets) to tracked vehicles and unpressurized bays in high-altitude unmanned aerial vehicles (UAVs). The ruggedness and huge bandwidth provided by VPX make it a natural choice for many projects. However, one application space that benefits more than most from the processing power of VPX is electronic warfare (EW) and military sensor processing (SP) systems.

Thanks to its flexibility, performance, and suitability for harsh and varied environments, VPX - especially the size, weight, and power-cost (SWaP-C)-friendly 3U VPX - has rapidly established itself as the form factor of choice for aerospace and defense programs. The majority of new opportunities are in the 3U VPX VITA 48.2 (conduction cooled) form factor, housed in an ARINC 404 enclosure, commonly called Air Transport Rack (ATR). ATR enclosures are notorious for restrictive I/O limitations.

Many of the standards developed by VITA working groups are for defining modules that are part of Open System Architectures (OSA) - whether they are VME, VPX, PMC, FMC or one of many other standards. These modules are used to build critical embedded systems that are deployed in a variety of application platforms. Today these platforms are typically connected via a network, a network that is often susceptible to cyberattacks. This article introduces you to high level concerns and challenges facing designers using Open System Architecture (OSA) modules.
