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.
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.
WHEA "builds on the PCI Express Advanced Reporting to provide more detailed information about system errors and a common reporting structure." [4] WHEA allows third-party software to interact with the operating system and react to certain hardware events.
Originally developed by the Personal Computer Memory Card International Association (), the ExpressCard standard is maintained by the USB Implementers Forum ().The host device supports PCI Express, USB 2.0 (including Hi-Speed), and USB 3.0 (SuperSpeed) [2] (ExpressCard 2.0 only) connectivity through the ExpressCard slot; cards can be designed to use any of these modes.
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 ...
1U 1-slot 32-Bit PCI Riser Card 2U 3-slot 32-Bit PCI Riser Card. A riser is usually connected to the mainboard's slot through an edge connector, though some, such as NLX and Next Unit of Computing Extreme, instead are plugged into an edge connector on the mainboard itself.
The preferred interface for video cards then became Accelerated Graphics Port (AGP), a superset of PCI, before giving way to PCI Express. [5] The first version of PCI found in retail desktop computers was a 32-bit bus using a 33 MHz bus clock and 5 V signaling, although the PCI 1.0 standard provided for a 64-bit variant as well. [6]
The PCI/104-Express specification establishes a standard to use the high-speed PCI Express bus in embedded applications. [1] It was developed by the PC/104 Consortium and adopted by member vote in March 2008. PCI Express was chosen because of its market adoption, performance, scalability, and growing silicon availability worldwide.
