RF Engines claims performance benchmark for pipeline FFT cores on an FPGA

RF Engines is claiming a new performance benchmark for commercially available pipeline fast fourier transform cores on an FPGA. The company’s HyperSpeed Plus cores process complex data streams in continuous real-time at data rates in excess of 52 Giga samples per second for a 2048 point FFT implemented on a Xilinx Virtex-6 FPGA device.  

The cores are intended for use in applications where extreme processing speed is required within minimum silicon resources, such as wideband surveillance and scientific or test instrumentation. The core can be combined with an ADC to make a real-time spectrum analyser.

The latest HyperSpeed FFT has been architected to run on Xilinx FPGAs, with lengths from 32 to 128K point and with longer lengths available by request.  Bit-widths and internal memory partitioning are adjustable.  All this is backed up by a fully bit-accurate Matlab model that is used to verify operation and tune performance as required.
