PLX Offers Webcast to Explain Reverse Bridging for PCI-X to PCI Express

3/4/2004 - PLX Technology (NASDAQ: PLXT,, the leading supplier of standard I/O interconnect silicon to the communications, server, storage and embedded-control industries, announced the next seminar in its series of TechOnline ( Webcasts on PCI ExpressTM technology. The Wednesday, March 10 (10:00 a.m. PST) PLX® Webcast, "Enabling Reverse Bridging in PCI-X-to-PCI Express Applications," will explain the newly developed concept of PCI Express-to-PCI/PCI-X reverse-mode bridging and highlight why bridges that lack this feature will not function in important applications.

The Webcast, PLX's sixth PCI Express seminar on TechOnline, is targeted at system architects and hardware/software engineers involved in PCI Express board and system development. It will provide them with background material on PCI Express, discuss various PCI Express applications for both forward and reverse bridging, address specific requirements to take advantage of this feature, and examine the essential functions delivered by a PCI Express bridge capable of reverse mode.

PLX recently demonstrated for the first time a forward/reverse PCI-X-to-PCI Express bridging device. The demonstration, unveiled at the Intel Developer Forum, transferred real-time captured digital images over a PCI Express link.

"TechOnline is a perfect forum to enlighten the engineering and design communities on the rich technical features of PCI Express and on the significant role those features will play in mainstream products when these systems are introduced this year," said Chris Youman, senior product marketing manager at PLX, who will be presenting next week's TechOnline seminar. "Because reverse bridging is a necessary feature for most of the PCI Express-based systems being considered at this time, we're structuring "Enabling Reverse Bridging in PCI-X-to-PCI Express Applications" as a comprehensive discussion on how this feature works and, when implemented, what it will do for the common applications PCI Express was developed to enhance. More importantly, we will explain why not having these features will significantly restrict the types of systems that can be built."

Leveraging Expertise, Driving
As with PLX's previous TechOnline Webcasts, the March 10 event leverages the company's long, successful history in the I/O interconnect market as a worldwide provider of PCI-based solutions to an array of industries. This experience is being applied to the development of the company's PCI Express products, scheduled for introduction the first half of this year and to be designed into systems expected to follow shortly thereafter. Through its PCI Express efforts, PLX also is streamlining the migration of designs using PCI to those based on PCI Express technology by working closely with board and system manufacturers to enhance their products.

PLX has been developing I/O interconnect solutions since 1986.
