how to deal with stream data to HDLFFT?

Hi.

When I run the example of CreateanFFTforHDLGenerationExample then I found 3*N,

Do I need 3*N for using HDLFFT? if I use HDLFFT8 then Do I need 24 loop?

How to deal with stream data to HDLFFT?

Implement FFT Algorithm for FPGA

HDL Coder, DSP HDL Toolbox, Simulink

This example shows how to implement a hardware-targeted FFT by using DSP HDL Toolbox™ blocks.

This post also has several examples on how to stream data to a design function including an FFT.
