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.
PCI eXtensions for Instrumentation (PXI) is a modular instrumentation platform originally introduced in 1997 by National Instruments.PXI is promoted by the 69-member PXI Systems Alliance (PXISA), whose sponsor members are (in alphabetical order) ADLINK, Cobham Wireless, Keysight Technologies, Marvin Test Solutions, National Instruments, Pickering Interfaces and Teradyne.
The virtual or physical functions available to the hypervisor or guest operating system depend on the PCIe device. [3] The SR-IOV allows different virtual machines (VMs) in a virtual environment to share a single PCI Express hardware interface. In contrast, MR-IOV allows I/O PCI Express to share resources among different VMs on different ...
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 ...
Being message-based (at the PCI Express layer), this mechanism provides some, but not all, of the advantages of the PCI layer MSI mechanism: the 4 virtual pins per device are no longer shared on the bus (although PCI Express controllers may still combine legacy interrupts internally), and interrupt changes no longer inherently suffer from race ...
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
The PCI-X standard was developed jointly by IBM, HP, and Compaq and submitted for approval in 1998. It was an effort to codify proprietary server extensions to the PCI local bus to address several shortcomings in PCI, and increase performance of high bandwidth devices, such as Gigabit Ethernet, Fibre Channel, and Ultra3 SCSI cards, and allow processors to be interconnected in clusters.
Related standards include CompactPCI Express and CompactPXI, which follow a similar concept, but substitute the protocols and signaling of PCI Express and PXI respectively. The abbreviations cPCI, CPCI, cPCIe, and CPCIe are colloquial terms and are not officially used by PICMG.
