PICMG

PICMG is a standards development organization in the embedded computing industry. Members work collaboratively to develop new specifications and enhancements to existing ones. The members benefit from participating in standards development, gain early access to leading-edge technology, and forging relationships with thought leaders and suppliers in the industry.

The original PICMG mission was to provide extensions to the PCI standard developed by PCI-SIG for a range of applications. The organization's collaborations eventually expanded to include a variety of interconnect technologies for industrial computing and telecommunications.[2] PICMG's specifications are used in a wide variety of industries including industrial automation, military, aerospace, telecommunications, medical, gaming, transportation, physics/research, test and measurement, energy, drone/robotics, and general embedded computing.

In 2011, PICMG completed its transfer of assets from the Communications Platforms Trade Association (CP-TA). Since 2006, CP-TA had been a collaboration of communications vendors, developing interoperability testing requirements, methodologies, and procedures based on open specifications from PICMG, The Linux Foundation, and the Service Availability Forum. PICMG has continued the educational and marketing outreach formerly conducted by members of the CP-TA marketing work group.[3]

the benefits of open specifications and standards include multiple sources, scalability and upgrades, a large ecosystem of interoperable products, proven and tested designs, etc. But they should not be confused with open source. Open source groups tend to focus on specific product designs where even the Gerber files, schematics, and mechanical drawings are included. This lends itself to monochrome, commodity products with little differentiation. Open specification/open standard groups on the other hand define focus on common interfaces for interoperable products rather than finished products. Multiple vendors contribute to the base definitions and interfaces, but the implementation varies greatly. The result is a variety of interoperable products with a wide range of applications.

For many years, PICMG used a numerical naming convention with specification being referred to as “PICMG X.YY”. Where X was used denoted differing form factors ("1" for slot card based single board computers, "2" for CompactPCI and "3" for AdvancedTCA) while YY was used to indicate incremental changes, option definitions or slight variation of a specification form its core specification. In 2003, PICMG added an acronym-based naming convention for its specifications to yield better results from internet search engines. Specifications are now often named ABCD.X where ABCD is an acronym of the specification. In this naming convention, base or main specification are denote with X=0 (i.e. ABCD.0) and PICMG subsidiary specifications are denoted X>0. PICMG subsidiary specifications represent how various options or variations of a based specification should be handled.
