PICMG introduced a new revision and upgrade to the CompactPCI Express specification, Revision 2. This revision of CompactPCI Express features interoperability at both the interface and product level, and increase performance. The latest specification will allow rapid adoption in instrumentation and control applications where performance and interoperability are critical. The PXI standard, which currently builds on top of CompactPCI and CompactPCI Express, will see immediate benefit from the new revision.
The new Revision 2 of the CompactPCI Express specification adds 5 gigabits per second transfer rate and 8 gigabits per second transfer rate PCI Express operation. This provides up to 4 times the bandwidth while maintaining full backwards compatibility with previous CompactPCI and CompactPCI Express products. In addition, the latest specification defines how a product’s PCI Express signaling is validated to ensure interoperability.
CompactPCI is a standard for a implementing a wide range of communications, industrial automation, instrumentation, and military and aerospace applications. It uses the popular and proven Eurocard 3U and 6U mechanical standards and can be convention or conduction cooled. CompactPCI Express, which was first introduced in 2005, added PCI Express signaling capability across the backplane while maintaining backwards compatibility with earlier versions of CompactPCI. CompactPCI Express is popular in the same applications as original CompactPCI, and provides higher performance with little or no increase in cost.
The CompactPCI family of standards has been growing since the original version was ratified in 1995, and represents over $500M in annual revenues. CompactPCI was the first open standard that provided reliable hot swap operation and was the first standard to incorporate a switched Ethernet backplane fabric in 2000. More recent versions, CompactPCI Express and CompactPCI Serial, are optimized for instrumentation and control applications and take advantage of newer serial communications standards.
Founded in 1994 as the PCI Industrial Computer Manufacturers Group (PICMG), which was founded in 1994, is a consortium of over 250 companies that collaboratively develops open specifications for high performance telecommunications, military and industrial computing applications.
