PCI Express (PCIe) has been around since 2003, and in that time it has managed to become the primary data interconnect for not only expansion cards, but also high-speed external devices. What also ...

In another example of superior architecture, the Power Mac G4 optimises PCI performance by connecting the PCI bus directly to the system controller. In a typical PC architecture, PCI devices connect ...

The XIO2001 is a single-function PCI Express to PCI translation bridge that is fully compliant to the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. For downstream traffic, the bridge ...

This Design Idea describes a VHDL implementation of a PCI 2.2-bus arbiter (Figure 1). Any PCI system may have one or more PCI-master devices. Most devices can behave as target hosts, but one must be a ...

A brief timeline of PC graphics bus interfaces. The history of the Peripheral Component Interconnect (PCI) bus. The status of the current industry-standard PCI Express (PCIe) bus. Prior to the PC era, ...

Why the need for PCI Express? As processor clock speeds increase, parallel buses such as PCI become harder to implement. Signal skew and fan-out restrictions restrict the bandwidth achievable on a ...

If rumors floating around the 'Net are true, Intel is set to drop support for the PCI (Peripheral Component Interconnect) bus when it launches its next-generation 6-series of chipsets with support for ...

OPINION: When new PC standards come online there is a danger to assume that the benefit will come from an immediate performance boost. Danger because one of the defining features that sets modern ...

If the datacenter had been taken over by InfiniBand, as was originally intended back in the late 1990s, then PCI-Express peripheral buses and certainly PCI-Express switching – and maybe even Ethernet ...

The early days of home computing were quite a jungle of different standards and convoluted solutions to make one piece of hardware work on as many different platforms as possible. IBM’s PC was an ...

Adopted by the PCI SIG -- the industry group that looks after the bus definitions -- PCI Express aims to be the standard bus for the next ten years or so. PCI Express is similar to classic PCI in the ...

A motherboard's main job is to act as a conduit between the various hardware elements that make up a PC. It needs to be able to link the desired CPU(s), system memory, graphics card, hard drive(s), ...
