PCI / PCI EXPRESS / cPCI


PCI ExpressPCIe, or PCI-E (not to be mistaken forPCI-X) is an implementation of the PCI computer bus that uses existing PCI programming concepts, but bases it on a completely different and much faster serial physical-layer communications protocol. PCIe transfers data at 250 MB/s (238 MiB/s), per channel to a maximum of 16 channels, a total combined transfer rate of 4GB/s (3.7 GiB/s).

CompactPCI (cPCI) system is a 3U or 6U Eurocard-based industrial computer, where all boards are connected via a passive PCI backplane. The pin assignments of the connectors are documented in standards, published by the organisation PICMG US and PICMG Europe. PICMG stands for PCI Industrial Computers Manufacturers Group. The connectors and the electrical rules allow for 8 boards in a PCI segment. Multiple segments are allowed with bridges.

PXI Express
Fully integrated in the PXI platform with backward software and hardware compatibility, PXI Express gives PXI users up to 2 GB/s dedicated per-slot bandwidth and the industry’s highest-performance timing and synchronization capabilities. To provide an infrastructure compatible with both the new features of PXI Express and existing PXI modules, National Instruments introduces the first PXI Express chassis and controllers.

PCI eXtensions for Instrumentation (PXI) is the open, multivendor standard for measurement and automation that delivers more than 10 times the performance of older measurement and automation architectures. With PXI, you automatically benefit from the low cost, ease of use, modularity, and flexibility of PC technology.
