Mixed Radix FFT
Overview
Radix-2 or -4 FFT algorithms lend themselves nicely to parallel FPGA or ASIC logic implementation. However, real-world processing often requires non power-of-2 or -4 FFT lengths for spacing into the desired frequency bin size, called mixed-radix FFTs.
Key Features
- 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
- Mixed radix-2, 3, 5, and 7 lengths available
