FOR IMMEDIATE RELEASE

XILINX JOINS FELLOW INDUSTRY LEADERS ON ADVANCED SWITCHING INTERCONNECT SPECIAL INTEREST GROUP BOARD OF DIRECTORS
New Advanced Switching Specification to Accelerate the Convergence of Computing and Communications Platform Architectures

SAN JOSE, Calif., September 30, 2003 - Xilinx, Inc. (NASDAQ:XLNX), the world's leading programmable logic supplier, today announced that it will serve on the Advanced Switching Interconnect Special Interest Group (ASI-SIG) Board of Directors. The newly created ASI-SIG was formed to oversee the development of an Advanced Switching* specification - the communications oriented complement to the PCI Express* interconnect standard - and accelerate its industry-wide adoption. Fellow Board member representation includes Agere, Alcatel, Huawei, Intel, Siemens, and Vitesse.

Today's news represents a key milestone in the movement toward an Advanced Switching specification. As members of the ASI-SIG Board of Directors, Xilinx and other industry-leading companies will work to identify, promote and establish open, standard fabric technology interfaces that will complement and maximize the PCI Express foundation. Together, the complementary PCI Express and Advanced Switching technologies ensure mainstream, broadly available building blocks and tools that enable component and equipment makers to reuse technology across multiple products, reduce design costs and shorten the time it takes to get products to market.

"It's an honor for Xilinx to have been invited to serve on the ASI-SIG Board of Directors," Mark Aaldering, senior director of the IP Solutions Division at Xilinx. "Xilinx was the first to deliver PCI Express IP core technology to the industry and our participation in the ASI-SIG reaffirms our commitment to deliver industry-leading PCI Express solutions. Together, the members will help drive the adoption of an industry-wide standard. Xilinx is excited to be part of a concerted industry effort that will have far reaching effects."

"Xilinx's plans to develop Advanced Switching technology in communications and embedded markets segments will help accelerate the adoption the specification," said Rajeev Kumar, president of the ASI-SIG and advanced switching technology manager at Intel. "Programmable logic from companies like Xilinx will help accelerate the proliferation of Advanced Switching and allow the industry to benefit from the investments made in PCI Express technology."

The Advanced Switching Specification
The Advanced Switching specification is a switched interconnect and data fabric technology based on the PCI Express architecture for joining components and system boards in low-to-midrange communications and embedded applications. The PCI Express architecture builds on the highly successful PCI standard, and was designed as the general-purpose chip-to-chip interconnect technology for the next decade.

Advanced Switching uses the same physical and link layers as the PCI Express architecture to achieve widespread interoperability and availability of technology. However, at the transaction layer, Advanced Switching is optimized to provide an array of specialized communications features, including high-availability functions, peer-to-peer and multicast networking, congestion and system management, scalability, and support for virtually any networking protocol. The optimized transaction layer provides the equipment developer extensive flexibility for designing value-added features into communications and embedded solutions.
