Virtex-5 SXT FPGAs for High Performance DSP Applications - Xilinx

Xilinx released 65nm Virtex-5 SXT FPGAs, optimized for high-performance DSP (digital signal processing) applications. The SXT platform supports 352 GMACs at 550MHz, consuming 35%  less power compared to the 90nm generations. Virtex-5 SXT FPGAs is the third of four Virtex-5 FPGA platforms, and ii is the first Xilinx’s DSP-optimized FPGA family to integrate serial transceivers.

The Xilix Virtex-5 SXT platform offers three new device options that meet the ultra-high bandwidth DSP  for tomorrow video and wireless applications.

The Virtex-5 SXT platform is suitable for high-performance digital signal processing applications, such as HD video and WIMAX. The enhanced DSP slice (DSP48E) includes a 25×18-bit multiplier, a 48-bit second stage for accumulation and arithmetic operations, and a 48-bit output that can be expanded to 96-bits.

The DSP slice, DSP48E, includes integrated cascade routing enabling parallel processing at full 550-MHz,  delivering an industry-leading 352 GMACs of DSP performance using the 640 DSP48E blocks available in the largest Virtex-5 SXT device. Additional capabilities include an independent C register and an expanded second stage with support for SIMD operations and pattern detection for more efficient DSP implementation.

The SXT meets the ever-increasing I/O bandwidth requirements of high-performance DSP applications with up to 16 low-power 3.2 Gbps RocketIO serial transceivers that support industry-standard protocols such as CPRI/OBSAI, HD/SDI, Serial RapidIO, PCI Express and Gigabit Ethernet specifications among others. PCI Express and Gigabit Ethernet standards are supported with built-in protocol blocks and interfaces.

Virtex-5 SXT devices are supported by C/C++, VHDL, MATLAB, Simulink, and Verilog development tools.

The SXT logic density is 35,000 to 95,000 logic cells and have 192 to 640 dedicated DSP48E slices. It  enables developers to select the right mix of features to optimize overall system cost. Virtex-5 SXT also offer the high memory-to-logic ratio to accommodate memory-intensive requirement in video processing and imaging applications.

The SX50T device expected to be available in second half of 2008. Price is US$299 (1K unit). Sample is available now.
