The VME, CompactPCI® and Multibus suppliers have joined forces to agree on a common standard for mezzanine boards. The result is PMC (PCI Mezzanine Card) - a mezzanine bus based on the well established high performance PCI (Peripheral Component Interconnect) specification. PCI is now used by most high performance PC system suppliers and add-in card vendors. Hence, it is very well supported, low cost and readily available.
The PMC board can be installed and used with the most popular standards as such PCI, PCI-X, CompactPCI, VME and others in using off-the-shelf carrier boards.
