High-performance Low-memory Mixed Radix FFT
- Real or Complex valued IFFT/FFT options
- Per transform selection of FFT size from 8 to 32768 points
- Per transform selection of FFT or IFFT
- Efficient mixed radix 4/2 dragonfly for low cycle count
Mixed Radix FFT
- lengths other than radix-2 possible (i.e. 768, 256 x 3)
- Parallel FFT structures to increase performance
- Fixed or floating point math
- wide range of performance options
FFT Intel® FPGA IP Core
- The Fast Fourier transform (FFT) Intel FPGA intellectual property (IP) core is a high-performance, highly parameterizable FFT processor
- The FFT function implements a radix-2/4 decimation-in-frequency (DIF) FFT algorithm for transform lengths of 2m where 6 ≤ m ≤ 14, internally using a block-floating-point architecture to maximize signal dynamic range in the transform calculation.
