OKLAHOMA CITY – The American National Standards Institute (ANSI) in New York has ratified the VITA 46.0-2019 VPX baseline standard for critical embedded computing. ANSI/VITA 46.0-2019 has completed the VITA and ANSI processes reaching full recognition under guidance of VITA.
The 2019 revision of VITA 46.0 makes several deletions, clarifications, and updates to the capabilities defined in the standard to align with current requirements of VPX technology. VITA is the open standards, open markets embedded computing trade association in Oklahoma City.
The VPX base standard defines physical features that enable high-speed communication in a 3U or 6U backplane-based critical and intelligent embedded computing systems.
The VPX family of standards includes the ANSI/VITA 46.0 baseline standard; ANSI/VITA 46.1: VMEbus signal mapping; ANSI/VITA 46.3 Serial RapidIO; ANSI/VITA 46.4 PCI Express; ANSI/VITA 46.6 Gigabit Ethernet control plane on VPX; ANSI/VITA 46.7 Ethernet; ANSI/VITA 46.9 PMC/XMC rear I/O; ANSI/VITA 46.10 rear transition module; and ANSI/VITA 46.11 system management on VPX.

The ANSI/VITA 65.x architecture framework standards define system-level VPX interoperability for multi-vendor, multi-module, integrated system environments. Several other related standards add capability to VPX. Additional work is underway to improve the data rate of VPX to 25 gigabits per second.
The VITA/ANSI process requires that every active standard be reviewed every five years. The VITA 46 VPX working group started work in March 2003, ratifying a baseline VPX standard in 2007, and revised in 2013.
