Xilinx Virtex-4 FX
The Xilinx Virtex-4 family is revolutionizing the fundamentals of FPGA economics. The Virtex-4FX FPGAs delivers breakthrough performance at the lowest cost and offers a compelling alternative to ASICs and ASSPs. The high-performance Virtex-4FX processor provides fully featured solution for embedded platform application that want to take advantage of an FPGA.
Reference boards/OEM boards enabled:
The Virtex-4FX LinuxLink can also be used as a starting point for Linux development for designs derived from:
Notes:
Complete peripheral support for Virtex-4FX derived integrated processors, or board support for other reference designs, might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
Virtex-4FX devices are user-programmable gate arrays with various configurable elements and embedded cores optimized for high-density and high-performance system designs. Combining Advanced Silicon Modular Block (ASMBL™) architecture with a wide variety of flexible features, the Virtex™-4FX family from Xilinx greatly enhances programmable logic design capabilities, making it a powerful alternative to ASIC technology.
The wide array of Virtex-4FX hard-IP core blocks includes the PowerPC™ processors (with a new APU interface), tri-mode Ethernet MACs, 622 Mb/s to 6.5 Gb/s serial transceivers, dedicated DSP slices, high-speed clock management circuitry, and source-synchronous interface blocks. The basic Virtex-4 building blocks are enhancements of those found in the popular Virtex, Virtex-E, Virtex-II, Virtex-II Pro, and Virtex-II Pro X product families, Virtex-4FX devices are produced on a state-of-the-art 90-nm copper process using 300-mm (12-inch) wafer technology.
