Xilinx and Integrated Silicon Systems announce stategic development agreement

XILINX AND INTEGRATED SILICON SYSTEMS ANNOUNCE STRATEGIC DEVELOPMENT AGREEMENT

Deal creates one-stop source for multimedia and communication cores for Xilinx FPGAs

SAN JOSE, Calif., June 26, 2000-Xilinx, Inc. (NASDAQ: XLNX) and Integrated Silicon Systems Ltd. (ISS) today announced a strategic development and OEM agreement under which ISS will provide versions of its multimedia and communications cores for Xilinx® FPGAs. The IP cores will be available for purchase as Xilinx LogiCORE^TM products, downloadable from the Xilinx IP Center, and optimized for Xilinx devices and design tools. The agreement strengthens Xilinx leadership in the programmable logic industry by providing a one-stop source for complete system-level solutions.

In an associated announcement, Xilinx and ISS today announced the immediate availability of the first three communications cores resulting from this partnership.

"This agreement broadens our long-term and successful relationship with Xilinx," said Stephen Roddy, vice president of sales and marketing at ISS. "The strength of the Xilinx Virtex architecture coupled with a commitment by Xilinx to partnerships provides a perfect environment to expand the usage of ISS cores in wireless, wired communications, digital video and imaging applications. With this agreement, Xilinx can now fully utilize our expertise in multimedia communications to provide high performance, off-the-shelf design solutions."

The ISS cores under the OEM agreement are designed to operate with the latest Xilinx FPGAs, including Virtex^TM, Virtex-E, Spartan®-II and future FPGA families. Xilinx will deliver these LogiCORE products using the Xilinx CORE Generator tool to smoothly integrate the cores into the Xilinx design flow.

"ISS has achieved industry-wide recognition for solving the needs of the communications and multimedia user community," said Mark Aaldering, senior director for the IP Solutions Division at Xilinx. "By partnering with ISS, Xilinx is able to address the demand for a one-stop source of high-quality, cost-effective, optimized FPGA cores. This agreement expands the successful long-term relationship between ISS and Xilinx which started with membership in the Xilinx AllianceCORE^TM third-party party IP development program and was furthered through the co-development partnership for Reed-Solomon forward error correction LogiCORE products. The agreement reinforces a commitment by Xilinx to provide leading-edge IP for multi-million gate FPGA designs."

The first three cores to result from the Xilinx-ISS agreement are now available and include a 32-channel HDLC controller, a single-channel HDLC controller, and a 32-channel ADPCM codec. Licensing information and instructions for downloading the cores can be found on the Xilinx IP Center. Information on other Xilinx LogiCORE and third-party AllianceCORE products is also available from the IP Center.
