The PCI-SIG is distinct from the similarly named and adjacently-focused PCI Industrial Computer Manufacturers Group. It has produced the PCI , PCI-X and PCI Express specifications. As of 2024, the board of directors of the PCI-SIG has representatives from: AMD , ARM , Dell EMC , IBM , Intel , Synopsys , Keysight , NVIDIA , and Qualcomm .
The Payment Card Industry Data Security Standard (PCI DSS) is an information security standard used to handle credit cards from major card brands.The standard is administered by the Payment Card Industry Security Standards Council, and its use is mandated by the card brands.
PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, Mini PCI-E, mPCIe, and PEM), based on PCI Express, is a replacement for the Mini PCI form factor. It is developed by the PCI-SIG . The host device supports both PCI Express and USB 2.0 connectivity, and each card may use either standard.
Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor upgrades.
PICMG, or PCI Industrial Computer Manufacturers Group, is a consortium of over 140 companies in the fields of computer science and engineering. [1] 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.
This traditional form of interrupt signalling is an out-of-band form of control signalling since it uses a dedicated path to send such control information, separately from the main data path. MSI replaces those dedicated interrupt lines with in-band signalling, by exchanging special messages that indicate interrupts through the main data path.
The PCI SIG strongly encourages 3.3 V PCI signaling, [16] requiring support for it since standard revision 2.3, [18] but most PC motherboards use the 5 V variant. Thus, while many currently available PCI cards support both, and have two key notches to indicate that, there are still a large number of 5 V-only cards on the market.
A peripheral using the PCI-SIG PCIe Address Translation Services (ATS) Page Request Interface (PRI) extension can detect and signal the need for memory manager services. For system architectures in which port I/O is a distinct address space from the memory address space, an IOMMU is not used when the CPU communicates with devices via I/O ports .
