PICMG
The PCI Industrial Computer Manufacturers Group (PICMG) is a consortium of over 227 companies. 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 now grown to include newer technologies. PICMG is distinct from the similarly named and adjacently-focused PCI Special Interest Group (PCI-SIG).
PICMG currently focuses on developing and implementing specifications and guidelines for open standards-based computer architectures from a wide variety of interconnects.
