Emerging standards such as VITA 100 and VNX+ will double board and backplane speeds, add a new board size, and help make tiny computers possible for handheld devices and uncrewed devices.

The aerospace and defense embedded computing industry is on the cusp of some of the biggest changes in more than a decade, as board and backplane speeds are increasing, board dimensions are about to expand by including a new size, and small-form-factor embedded computing architectures are poised to move to credit-card-sized modules.

The VITA open-standards organization, which oversees the leading design standards for much of the embedded computing industry, is near finishing the most influential change since the VITA 65 Open VPX standard was ratified in 2010.

"VITA 100 will double the pins on the backplane over the VITA 46 connector to provide twice as many high-speed connects," explains Aaron Frank, senior product manager at the Curtiss-Wright Defense Corp. Defense Solutions segment in Ashburn, Va.
