FPGA family opmitised for DSP

28 May 2008 Programmable Logic

Xilinx has released its digital signal processing (DSP)-optimised Virtex-5 SXT FPGAs. These devices are part of the Xilinx XtremeDSP portfolio of solutions that includes development kits, design software, IP and reference designs. The Virtex-5 SXT platform of devices is optimised for high performance and can deliver over 350 GMACs of fixed-point performance for many applications including wireless, test and measurement, and defence and up to 82,5 GFLOPS of floating-point DSP performance for applications such as medical imaging.

All three devices in the Virtex-5 SXT family are production-qualified and supported by the XtremeDSP portfolio of development tools and IP including System Generator for DSP, Core Generator, Platform Studio and ISE Foundation. The platform consists of three devices, SX35T, SX50T and SX95T, that offer a range in logic density from 35 000 to 95 000 logic cells and 192 to 640 dedicated DSP48E slices. Each device offers low-power RocketIO GTP serial transceivers, and built-in PCI Express Endpoint and tri-mode Ethernet MAC blocks.

The Virtex-5 family is said to be the industry's first FPGA to use 65 nm triple-oxide technology to reduce overall dynamic power consumption up to 35% while maintaining low static power consumption. The enhanced DSP48E block consumes only 1,4 mW/100 MHz typical at 38% toggle rate, and the RocketIO GTP transceivers consume as little as 100 mW typical at 3,2 Gbps.
