Xilinx Virtex-5 FXT FPGA

The Virtex(R)-5 FXT FPGA, from Xilinx, Inc. (Nasdaq: XLNX), is the industry’s first FPGA with embedded PowerPC(R) 440 processor blocks, high-speed RocketIO(TM) GTX transceivers and dedicated XtremeDSP(TM) processing capabilities. Virtex-5 FXT devices deliver high performance while enabling designers to reduce system costs, board space and component count. With support from Xilinx and providers of logic, embedded and DSP development tools, and IP cores, Virtex-5 FXT FPGAs deliver the ideal system integration platform for applications in: wired and wireless communications, audio/video broadcast equipment, military, aerospace, industrial systems, and many others.

Virtex-5 FXT FPGA samples are now shipping for the FX30T and FX70T devices. The remaining FX100T, FX130T and FX200T devices will be available over the next six months with the first production devices scheduled to be made available in the third quarter of 2008. The FX30T device will list for US$159 in 1,000 unit volumes by the second half of 2009. The Virtex(R)-5 EasyPath(TM) program supports Virtex-5 FXT devices for high-volume cost reductions.

The Virtex-5 FXT platform offers the first FPGAs to provide up to two industry-standard PowerPC 440 processor blocks. Each processor, with integrated 32KB instruction and 32KB data caches, delivers up to 1,100 DMIPS at 550 MHz. Tightly coupled to the PowerPC440 blocks is a new integrated 5×2 cross bar processor interconnect architecture that provides simultaneous access to I/O and memory. Highly integrated, this innovative interconnect architecture includes dedicated master and slave processor local bus interfaces, four DMA ports with separate transmit and receive channels, and a dedicated memory bus interface enabling high-performance, low latency point-to-point connectivity.

Designers can rapidly and easily implement advanced scalable embedded processing applications using the PowerPC 440 embedded processor blocks. The advanced PLB architecture maximizes data transfers between the processor, crossbar and soft IP logic with high-throughput 128-bit interfaces to help minimize system bottlenecks. Also, the enhanced high-performance Auxiliary Processor Control Unit (APU) provides added connectivity for dedicated co-processing engines or custom user defined instructions in applications such as video processing, 3D data processing and floating-point math.

With the release of EDK 10.1, the PowerPC440 block in Virtex-5 FXT is supported by industry standard operating systems including Wind River Systems, Green Hills, and other key embedded OS providers. Linux support is provided through MontaVista, Wind River Systems with others soon to be added. In addition, Xilinx is actively engaged in the open source Linux community.

To address the growing demand for higher I/O bandwidth, the Virtex-5 FXT platform includes high-performance, low-power RocketIO GTX transceivers capable of supporting data rates from 500 Mbps to 6.5Gbps. Customers can design applications supporting standards such as XAUI, Fibre Channel, SONET, Serial RapidIO, PCI Express(R) 1.1 and 2.0, Interlaken, and others. Consuming less than 200mW typical power per channel at 6.5Gbps, the GTX transceivers come with many advanced features such as 4-tap DFE receiver equalization in addition to linear equalization and transmit pre-emphasis to improve signal integrity at higher line rates. The new transceiver blocks also include a unique multi-code physical coding sublayer to support both 64B/66B and 64B/67B encoding/decoding schemes saving thousands of logic cells for each channel. In addition, cross-platform pin compatibility enables customers who have designs targeting Virtex-5 LXT and SXT devices to migrate their designs to Virtex-5 FXT devices in order to take advantage of the higher-performance embedded processing and serial connectivity.

The Virtex-5 FXT platform includes up to 384 DSP slices and 16.5 Mb of internal memory that can be configured to provide over 190 GMACs of DSP processing performance and 92 tera-bits/sec of memory bandwidth respectively at 500 MHz. This balance of hardware resources maximizes the performance for computation-intensive applications typical of DSP and video applications. The DSP48E slice, available in all XtremeDSP(TM) Virtex(R)-5 devices, enables higher levels of DSP integration and lower power consumption than previous-generation Virtex devices. Over 40 dynamically controlled operating modes are supported including: multiplier, multiplier-accumulator, multipler-adder/subtractor, tree input adder, barrel shifter, wide counters and comparators.
