XionLogic's open source FFT processor cores with configurable FFT lengths and I/O widths are available for download for free under BSD license. The RTL designs are provided in Verilog-2001 with appropriate test-benches and test vectors. All FFT cores are functionally verified in simulation and synthesised for Xilinx Spartan-6 devices.

• Radix-2 decimation in frequency FFT core
• Radix-2 constant-geometry structure FFT core
• Radix-2² single-path delay feedback FFT core
