I just heard from my old buddy Tom Dillon, the president of Dillon Engineering (www.DillonEng.com), that they are announcing the availability of their UltraLong FFT IP Core for Xilinx FPGAs. Apparently this is a pipelined Fast Fourier Transform (FFT) processor targeted specifically to Xilinx FPGAs.
Tom tells me that this UltraLong FFT IP Core uses an efficient Fast Fourier Transform (FFT) algorithm to provide multimillion-point discrete transforms on data frames or continuous data streams. This structure utilizes state-of-the-art off-chip memory technology and N1- and N2-length pipelined radix-2 FFT engines with an additional rotation stage to perform N=N1×N2 transform lengths, up to 64M points. The UltraLong IP Core is easily targeted to current Xilinx FPGA devices and various external memory types.
UltraLong FFT IP features:
- Radix-2 FFT lengths
- IEEE 754 Floating Point or Fixed Point
- Run-time length selection (1K to 64M)
- Run-time selectable Forward or Inverse FFT
- 250 MSamples/seconds
- Natural order I/O
- C/C++ and MATLAB bit accurate models
- Netlist and full source versions available
