SAN JOSE, Calif., November 23, 1998 -- Xilinx, Inc., (NASDAQ:XLNX) today announced two new AllianceCORE products aimed at enhancing Internet data security and bandwidth. 

The new cores, available immediately from AllianceCORE partners Memec Design Services and CoreEl MicroSystems, include a Data Encryption Standard (DES) engine core and an HDLC controller core designed specifically to support the emerging Point-to-Point Protocol over SONET (POS) communications standard. 

"The Internet is an exciting new arena for programmable logic," said Rich Sevcik, senior vice president of software, cores and support at Xilinx. "Manufacturers embracing Xilinx Internet Reconfigurable Logic technology to upgrade FPGA-based network appliances over the network will need a steady supply of cores to help them implement their Internet equipment designs. To assist this, we have partnered with intellectual property providers to help bolster the Internet infrastructure with new programmable logic cores like these." 

Enhancing Internet Security 
The XF-DES Data Encryption Standard engine core from Memec Design Services is used to establish secure Internet transactions when employed in remote access servers as well as satellite and cable and data modems. The core supports both single- and triple-DES modes of operation. In single-DES mode the core supports data throughput in excess of 155 Mbps (OC-3 speeds). It is one of the only DES cores on the market to be certified by the U.S. National Institute of Standards and Technology (NIST). The core is already in use by several Xilinx customers. 

"We see a bright future for the Internet Reconfigurable Logic concept. Since security is a concern for Internet users, our XF-DES engine core provides an effective solution for Internet applications that require increased levels of security," said Timothy Smith, managing director of Memec Design Services. "Coupled with the low cost and high performance of the new XC4000XLA and SpartanXL FPGAs, this solution is also cost-effective for Internet systems that typically sell in very high volumes." 

Improving Internet Bandwidth 
CoreEl MicroSystems’ PPP8 HDLC core is a critical part of the circuitry used to improve Internet bandwidth by packaging Internet traffic for transport over existing high-speed SONET networks. The core conforms to the RFC1619 Point-to-Point Protocol (PPP) over SONET and 
RFC1662 PPP in the HDLC framing specifications. The core is delivered as two modules, supporting transmit and receive operations separately. 

“The PPP8 HDLC core can operate at speeds of up to 80 MHz on the Xilinx XC4000 FPGA family and at higher speeds on the new Virtex family,” said Chetan Sanghvi, president of CoreEl MicroSystems. “As a result, IRL equipment using this FPGA-based solution can support PPP over SONET/SDH at 155 Mbps as well as 622 Mbps speeds.” 

Availability and Pricing 
Both cores are available today in Xilinx netlist formats. The XF-DES core can be purchased directly from Memec Design Services for $5,000.  The Verilog source code version has a list price of $15,000, which includes a test bench. The PPP8 HDLC core lists for $22,000 and can be purchased directly from CoreEl MicroSystems. Source code for the CoreEl core is available at extra cost.
