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.
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.
