PICMG 2.0 R3.0 CompactPCI a Specification

CompactPCI is an adaptation of the Peripheral Component Interconnect (PCI)
Specification 2.1 or later for industrial and/or embedded applications requiring a
more robust mechanical form factor than desktop PCI. CompactPCI uses industry
standard mechanical components and high performance connector technologies to
provide an optimized system intended for rugged applications. CompactPCI provides
a system that is electrically compatible with the PCI Specification, allowing low cost
PCI components to be utilized in a mechanical form factor suited for rugged environments.
CompactPCI is an open specification supported by the PICMG (PCI Industrial Computer
Manufacturers Group), which is a consortium of companies involved in utilizing
PCI for embedded applications. PICMG controls this specification.
1.2 Background and Terminology
Eurocard - A series of mechanical board form factor sizes for rack-based systems as
used in VME, Multibus II, and other applications defined by the Institute of Electrical
and Electronics Engineers (IEEE) and International Electrotechnical Committee
(IEC).
ISA - Industry Standard Architecture. A specification by which Personal Computers
(PCs) add boards.
PCI - Peripheral Component Interconnect. A specification for defining a common interconnect
between logic components. Typically used for interconnecting high-speed,
PC-compatible chipset components. The PCI specification is issued through the PCI
Special Interest Group (PCI SIG).
This specification utilizes several key words, which are defined below:
may: A key word indicating flexibility of choice with no implied preference.
shall: A key word indicating a mandatory requirement. Designers shall implement
such mandatory requirements to ensure interchangeability and
to claim conformance with the specification.
should: A key word indicating flexibility of choice with a strongly preferred
implementation.
