PICMG 2.14 is a specification by PICMG (PCI Industrial Computer Manufacturers Group) that defines a packet-based communications between heterogeneous PCI (Peripheral Component Interconnect) agents (multi-computing) within the CompactPCI (3U or 6U Eurocard-based industrial computer) [1] system architecture. [2]
CompactPCI is a computer bus interconnect for industrial computers, combining a Eurocard-type connector and PCI signaling and protocols. Boards are standardized to 3U or 6U sizes, and are typically interconnected via a passive backplane. The connector pin assignments are standardized by the PICMG US and PICMG Europe organizations. The connectors and the electrical rules allow for eight boards in a PCI segment. Multiple bus segments are allowed with bridges.
A blade server is a stripped-down server computer with a modular design optimized to minimize the use of physical space and energy. Blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. Unlike a rack-mount server, a blade server fits inside a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system, which may itself be rack-mounted. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole.
PICMG, or PCI Industrial Computer Manufacturers Group, is a consortium of over 140 companies in the fields of computer science and engineering. Founded in 1994, the group was originally formed to adapt PCI technology for use in high-performance telecommunications, military, and industrial computing applications, but its work has grown to include newer technologies. PICMG currently focuses on developing and implementing specifications and guidelines for open standards–based computer architectures from a wide variety of interconnects.
Advanced Telecommunications Computing Architecture is the largest specification effort in the history of the PCI Industrial Computer Manufacturers Group (PICMG), with more than 100 companies participating. Known as AdvancedTCA, the official specification designation PICMG 3.x was ratified by the PICMG organization in December 2002. AdvancedTCA is targeted primarily to requirements for "carrier grade" communications equipment, but has recently expanded its reach into more ruggedized applications geared toward the military/aerospace industries as well. This series of specifications incorporates the latest trends in high speed interconnect technologies, next-generation processors, and improved Reliability, Availability and Serviceability (RAS).
Advanced Mezzanine Cards are printed circuit boards (PCBs) that follow a specification of the PCI Industrial Computers Manufacturers Group (PICMG). Known as AdvancedMC or AMC, the official specification designation is AMC.x. Originally AMC was targeted to requirements for carrier grade communications equipment, but later used in other markets.
ETX, standing for Embedded Technology eXtended, is an integrated and compact 95 × 125 mm (3.7 × 4.9 in) computer-on-module (COM) form factor, which can be used in a design application much like an integrated circuit component. Each ETX COM integrates core CPU and memory functionality, the common I/O of a PC/AT, USB, audio, graphics, and Ethernet. All I/O signals as well as a full implementation of ISA and PCI buses are mapped to four high-density, low-profile connectors on the bottom side of the module.
COM Express, a computer-on-module (COM) form factor, is a highly integrated and compact computer that can be used in a design application much like an integrated circuit component. Each module integrates core CPU and memory functionality, the common I/O of a PC/AT, USB, audio, graphics (PEG), and Ethernet. All I/O signals are mapped to two high density, low profile connectors on the bottom side of the module. COM Express employs a mezzanine-based approach. The COM modules plug into a baseboard that is typically customized to the application. Over time, the COM Express mezzanine modules can be upgraded to newer, backwards-compatible versions. COM Express is commonly used in Industrial, military, aerospace, gaming, medical, transportation, Internet of things, and general computing embedded applications.

CompactPCI PlusIO is an extension to the PICMG 2.0 CompactPCI industrial standard for modular computer systems. CompactPCI PlusIO was officially adopted by the PCI Industrial Computer Manufacturers Group PICMG as PICMG 2.30 CompactPCI PlusIO in November 2009. Being 100% compatible with CompactPCI, PICMG 2.30 defines a migration path to the future CompactPCI Serial standard. It defines a fixed rear I/O pin assignment that focuses on modern, fast serial point-to-point connections. The new technology succeeding parallel CompactPCI comprises both CompactPCI Serial and CompactPCI PlusIO.
CompactPCI Serial is an industrial standard for modular computer systems. It is based on the established PICMG 2.0 CompactPCI standard, which uses the parallel PCI bus for communication among a system's card components. In contrast to this, CompactPCI Serial uses only serial point-to-point connections. CompactPCI Serial was officially adopted by the PCI Industrial Computer Manufacturers Group PICMG as PICMG CPCI-S.0 CompactPCI Serial in March 2011. Its mechanical concept is based on the proven standards of IEEE 1101-1-1998 and IEEE 1101-10-1996. CompactPCI Serial includes different connectors that permit very high data rates. The new technology standard succeeding parallel CompactPCI comprises another specification called PICMG 2.30 CompactPCI PlusIO. This is why CompactPCI Serial and CompactPCI PlusIO as a whole were also called CompactPCI Plus. PICMG's first working title of CompactPCI Serial was CPLUS.0. CompactPCI Serial backplanes and chassis are developed by Schroff, Elmа, and Pixus Technologies companies, as for the CompactPCI Serial board level electronics – they are developed by MEN Mikro Elektronik, Fastwel, EKF, Emerson Embedded Computing, ADLINK, and Kontron.
PICMG 1.3 is a PICMG specification which is commonly referred to as SHB Express. SHB Express is a modernization of PICMG 1.0 single-board computer specification. SHB Express, or System Host Board – Express, uses the same physical form factor as PICMG 1.0 boards. The board-to-backplane interfaces are PCI Express instead of PCI and ISA, although the use of PCI remains as an option.
PICMG 2.9 is a specification by PICMG that defines an implementation of a system management bus in a CompactPCI system. This system management bus uses an I2C hardware layer, and is based on the Intelligent Platform Management Interface (IPMI) and Intelligent Platform Management Bus (IPMB) specifications.
PICMG 2.2 is a specification by PICMG that standardizes pin assignments for PICMG 2.0 CompactPCI to include VME64 Extensions.
PICMG 2.3 is a specification by PICMG that standardizes user IO pin mappings from IEEE 1386 PMC sites to CompactPCI's J3/P3, J4/P4, and J5/P5 connections on a CompactPCI backplane
PICMG 2.4 is a specification by PICMG that standardizes user IO pin mappings from ANSI/VITA standard IP sites to J3/P3, J4/P4, and J5/P5 on a CompactPCI backplane.
PICMG 2.5 is a specification by PICMG that standardizes the utilization of CompactPCI user definable pins for the computer telephony functions of standard TDM bus, telephony rear IO, 48 VDC and ringing distribution in a 6U chassis environment.
PICMG 2.10 is a specification by PICMG that defines the use of the keying mechanisms defined in IEC 1076-4-101 for the J4/P4 connector and in IEEE 1101.10 for handle and cardguide hardware. Backplanes can be designed for 3.3V VIO or 5V VIO operation. These are differentiated by having 'Cadmium Yellow' colored keys for 3.3V or 'Brilliant Blue' color for 5V operation. If the cPCI card operates on a particular VIO voltage the card shall have the respective colored coding key. If the card is compatible with both voltages then it may not have any coding key. Other coding keys exists for use of backplanes and cards that support PICMG 2.5.
PICMG 2.11 is a specification by PICMG that defines the electrical and mechanical requirements relating to plug-in power modules in CompactPCI systems.
PICMG 2.12 is a specification by PICMG that defines vendor-independent software interfaces for supporting control of the software and hardware connection processes. The specification was updated in May 2002 to add Windows and Linux updates, Redundant System Slot (RSS) API, switched PCI-PCI bridging support, hardware and O/S-independent models of network-connected intelligent nodes, standards-based management of HS- and RSS-capable CompactPCI platforms and IDSEL to global address (GA) mapping.
