One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
The PCIe Root Complex holds a master copy of a 'Type 1 Configuration Table' that defines the host memory space that is accessible from each Endpoint device. In addition, each PCIe Endpoint device holds a master copy of their own memory space map in the host system memory as a 'Type 0 Configuration Table', this configuration table in each device ...
Configuration space may refer to: . Configuration space (physics) Configuration space (mathematics), the space of arrangements of points on a topological space PCI configuration space, the underlying way that the Conventional PCI, PCI-X and PCI Express perform auto configuration of the cards inserted into their bus
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.

A single physical PCI Express bus can be shared in a virtual environment using the SR-IOV specification. [1] [2] The SR-IOV offers different virtual functions to different virtual components (e.g. network adapter) on a physical server machine. SR-IOV uses physical and virtual functions to control or configure PCIe devices.
