Quality Supplier of Semiconductor Intellectual Property

Integrated Silicon Systems (ISS), The Multimedia ASVC Company(TM), announced today a strategic development and OEM agreement with Xilinx, Inc. Under the agreement, ISS will provide Application Specific Virtual Components (ASVCs), a form of licensable semiconductor intellectual property (IP), to Xilinx, Inc. In this first phase of the agreement, ISS delivered Adaptive Differential Pulse Code Modulation (ADPCM) codecs and High-Level Data Link Control (HDLC) protocol controllers optimized for Xilinx products.

ISS provided the ADPCM codecs and HDLC protocol controllers in pre-implemented, pre-optimized netlists for each supported Xilinx technology family. Xilinx will sell these cores to its customers for use in Xilinx devices. By using ISS' off-the-shelf products, Xilinx is able to offer greater value to their communications customers by providing a one-stop source to integrate IP solutions into Xilinx FPGAs.

"This multi-phase agreement with Xilinx expands the success of ISS' ASVCs and further validates the firm IP paradigm," said James G. Doherty, CEO of ISS. "This OEM agreement with Xilinx enables us to take advantage of the rapid expansion of IP use in FPGAs. These products address high growth communications applications ranging from Internet routers and switches to VoIP gateways. We will continue to leverage our expertise in multimedia communications to provide the highest-performance, off-the-shelf-design solutions available in the market today."

ISS delivers its market leading ASVCs in targeted netlist, or firm, format. By offering solutions as firm IP, ISS provides the full benefits of IP portability and reusability; the silicon optimization needed to meet the performance, power, and device area requirements of today's leading semiconductor designs; and the time-to-market advantage needed to compete in fast moving markets.

"The FPGA market is growing rapidly, particularly in the dynamic communications market segment. In order to meet fast paced time-to-market requirements, communications OEMs are relying more and more on semiconductor IP providers, such as ISS, for easy implementation and reuse," commented Stephen Roddy, vice president of sales and marketing for ISS. "As a member of the AllianceCORE program we have been delivering solutions to Xilinx's broad customer base for more than three years. This new OEM arrangement will accelerate the adoption of our products by FPGA customers."
