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 ...

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 ...

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 ...

PCI Express is a technology that consistently makes headlines, with new specifications boasting ever-improving performance regularly appearing in the news. It may come as a surprise, then, to learn ...

No matter what, system architects are always going to have to contend with one – and possibly more – bottlenecks when they design the machines that store and crunch the data that makes the world go ...

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 ...

For more than a decade the PCI bus has been the backbone of personal computers. Other systems, such as telephony and networking, adopted the technology for its cost and performance advantages. But now ...

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 ...
