3. Choose the Transform length, Data precision, and Twiddle precision.
4. Click the Architecture tab

5. Choose the FFT engine architecture, number of parallel FFT engines, and the I/O
1
data flow.
If you select the Streaming I/O data flow, the FFT MegaCore function
automatically generates a design with a Quad Output FFT engine architecture and
the minimum number of parallel FFT engines for the required throughput.
1
The twiddle factor precision must be less than or equal to the data
precision.
A single FFT engine architecture provides enough performance for up to a
1,024-point streaming I/O data flow FFT.
