SCOTTSDALE, Ariz., 5 Nov. 2007. VITA, the open-systems trade association in Scottsdale, Ariz., announced the ratification by ANSI of the VPX base standard under ANSI/VITA 46.0-2007 and the VMEbus Signal Mapping for VPX under ANSI/VITA 46.1-2007.
The VPX base standard sets the framework for the VPX suite of dot standards by defining the physical features of VPX. The VMEbus signal mapping provides a legacy migration pathway for previous generations of VMEbus technology to merge with the latest generation under VPX.
VPX is the latest backplane standard from VITA targeted to address the needs of critical embedded system including industrial control, medical, and aerospace applications. Various VME manufacturers worked together to shape VPX to meet the backplane I/O, processing and power distribution requirements of the critical embedded systems markets.
The formation of the VPX working groups to develop the specification suite was originally announced in January 2004.
"VPX certainly meets and exceeds the original goal of the standard to provide high-speed signals for both serial switch fabrics and high-speed I/O, as well as legacy VME protocols, for the spectrum of critical embedded systems," says Jing Kwok, chief engineer of modular solutions at Curtiss-Wright Controls Embedded Computing in Leesburg, Va.
"VPX provides at least twice the number of high-speed ports over other alternatives," Kwok says. "The specification also greatly expands the high-speed user I/O capacity and provides a broader ability to map high-speed user I/O or fabric connections to the backplane."
