PICMG Adopts CompactPCI PlusIO Specification

PICMG announces the adoption of the PICMG 2.30 specification, called CompactPCI® PlusIO. This new specification adds PCI Express, Ethernet, SATA, SAS, and USB extensions to the CompactPCI family of specifications while preserving PCI bus connectivity. The specification defines the use of previously reserved rear I/O pins for the 32-bit CompactPCI system slot with new high-speed serial signals to preserve interoperability with existing CompactPCI standards.

“This is an important technical addition to CompactPCI,” said Doug Sandy, vice president of technology for PICMG, “as it allows the use of advanced serialized busses found within all modern computer architectures for the embedded markets where CompactPCI is widely used. This avoids ‘fork-lift upgrades,’ while providing a clear path to today’s higher performance silicon.”

CompactPCI was initially ratified as PICMG 2.0 in 1995. As a passive backplane system based on PCI signaling, it defined compute and peripheral nodes using a 3U and 6U Eurocard form factors. Over the 14 year history of CompactPCI, PICMG has added subsidiary specifications to enhance functionality, and PICMG 2.30 represents the latest addition of these specifications.

Founded in 1994 as the PCI Industrial Computer Manufacturers Group, PICMG is a consortium of over 250 companies that collaboratively develops open specifications for high performance telecommunications, military and industrial computing applications.
