Xilinx Spartan-3 And Virtex-II Pro FPGAs Win Multiple Designs In Mangrove MPLS Platforms

Mangrove first to market with end-to-end MPLS networking solutionusing Xilinx low cost, high performance silicon and design tools

SAN JOSE, Calif., February 22, 2005 Xilinx, Inc., (NASDAQ: XLNX), the world's leading programmable logic supplier, today announced that Mangrove Systems, a leading provider of metro and access network infrastructure, has selected Xilinx 90nm cost-optimized Spartan-3™ and industry-leading Virtex-II Pro FPGA devices for use in its latest Piranha and Barracuda MetroMPLS (Multiprotocol Label Switching) Platforms. Combining Metro Ethernet Forum services, MPLS pseudowires, multi-service support and new efficient data-over-transport standards, the Mangrove product family enable carriers to transform existing SONET and SDH infrastructure into efficient, packet-aware metro and access networks.

Mangrove selected Spartan-3 FPGAs based on an exhaustive evaluation that covered price, performance, packaging that included high I/O count and density along with vendor commitment. Mangrove also chose Xilinx Virtex-II Pro FPGAs with embedded PowerPC processor and Multi Gigabit Transceivers (MGTs) for control plane functions and backplane interconnect.

Mangrove engineers optimized the use of a single design platform, Xilinx ISE (Integrated Software Environment) 6.3i, allowing easy portability of projects between their various design teams. Xilinx ISE design tools are optimized to make very efficient use of internal device features, significantly reducing overall development costs and time-to-market.

"The incorporation of Xilinx technology into our MetroMPLS platforms has enabled Mangrove to raise the bar on performance and define a new level of integration for the Metro and Access infrastructure," said Jonathan Reeves, Mangrove president and CEO. "The deployment of Fiber to the Home and migration to 3G wireless infrastructures requires higher bandwidth solutions at lower price points both of which the Xilinx technology helps us to achieve."

About Xilinx FPGAs
The 90nm Spartan-3 platform is the world's lowest-cost FPGA offering unrivaled price points with more density and performance features than any other device in its class. Spartan-3 devices feature an industry-leading combination of block and distributed RAM, up to 784 I/Os, MicroBlaze 32-bit RISC soft processors and XtremeDSP functionality with dedicated 18x18 multipliers that deliver up to 330 billion multiply and accumulates (MACs) per second.

Xilinx Virtex-II Pro and Virtex-4 devices are the only FPGAs in the industry to offer integrated PowerPC embedded technology and 3.125 Gbps serial transceivers. Announced Fall 2004, the Xilinx Virtex-4 family delivers more options, higher performance and lower power than any other FPGA family available today.
