Although the ability to expand a home computer with more RAM, storage and other features has been around for as long as home computers exist, it wasn’t until the IBM PC that the concept of a fully ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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), ...
