FOR IMMEDIATE RELEASE

XILINX AND ACCELIGHT TEAM TO DELIVER HIGH PERFORMANCE AGILE SERVICE AGGREGATION SOLUTIONS

Industry's fastest Virtex-II FPGAs are key enabler for the industry's first Photonic Service Switch

SAN JOSE, Calif., September 10, 2002 - Xilinx, Inc. (NASDAQ:XLNX) today announced a collaboration with AcceLight Networks, a leading aggregation switching and cross connect company, in the delivery of AcceLight's PXS 540 family of Photonic Service Switches (PSS). AcceLight's unique architecture, enabled by Xilinx's high-density, high-speed Virtex-II Platform FPGAs, delivers an integrated system for SONET/SDH STS-1 grooming, optical path and MPLS label switching from 80G to 1.28 terabits in capacity. Today's service providers can benefit from the agile service configurations of the PXS 540 to deliver inter-city TDM, optical, and MPLS switched services for the wavelength core.

AcceLight Networks is among a growing number of companies using Xilinx's leading-edge FPGAs to gain a competitive advantage. AcceLight selected Xilinx Platform FPGAs over competitive devices based upon the unprecedented logic, memory, and I/O capacity of the Virtex-II line.

"The advanced architecture and flexibility of the Xilinx Platform FPGAs helped us to shorten our development cycle and achieve the breakthrough performance offered in our PXS 540," said Paul Chow, director of ASIC technology at AcceLight Networks. "FPGAs are key to rapidly delivering the emerging technologies needed to build a flexible multi-services system that allows service providers to drive their costs down by up to 70%."

"AcceLight's innovative application of Xilinx FPGAs represents our ability to make a significant impact with enabling technologies for our customers," said Robert Bielby, senior director of Strategic Solutions at Xilinx. "AcceLight's patented architecture will have a significant impact in reducing operational costs for global service providers while providing a more efficient network."
