How to use fft in matlab hdl code to generate hdl code

Dear sir,

I am student of IIT Bombay.I am using Matlab R2012b and working for Image processing.

Sir I am working on matlab hdl coder to generate hdl code and implement on FPGA for SAR Image processing.SAR Image processing requires more fft computation.

Plz help me for how to generate HDL code for fft from matlab function file.

There are FFT and IFFT examples in the shipping documentation. For example, take a look at "HDL Implementation of LTE OFDM Modulator and Detector". This may not provide a drop in solution for you, but it will provide a demonstration of modeling a FFT using MATLAB code in Simulink.

From R2014b and later versions, 'FFT HDL Optimized' System Object is supported that you can generate HDL code from it.

Can we generate hdl code for a function containing subfunctions,like FFT and IFFT. Iam using dsp.HDLFFT and dsp.HDLIFFT objects. Please help
