6.2.5. Floating-Point FFT

This design example implements a floating-point, 512 point, radix 22 FFT. This design example accepts natural order data at the input and produces natural order data at the output. The design example includes a BitReverseCoreC block, which converts the input data stream from natural order to bit-reversed order, and an FFT_Float block, which performs an FFT on bit-reversed data and produces its output in natural order.

The model file is demo_fpfft.mdl.
