Parallel Butterfly FFT
Parallel butterfly structure for multiple point (rank-at-a-time) processing performance
The Parallel Butterfly FFT IP Core provides efficient continuous data FFT calculations at the rate of multiple points per clock cycle. A bank of parallel butterflies executes the FFT one rank at a time on multiple I/O streams.

Additional Information
Our FFT core is based on radix-2 reduction, which results in a very efficient implementation capable of any power-of-2 length FFT or IFFT (see also our FFT Datasheet or our Floating Point FFT Factsheet).
