I would like to know how many clocks cycles the FFTv4_1 require? Does anyone know how to determine the required clock cycles? I am using the System Generator 9.2i version.
Thank you so much!

calculating the FFT is not a "FIXED" clock cycle operation. It depends largely on the sample block size and the number of Add/Multiply/Address Fetches are calculated. the FFT algorithm takes care of the ADD/Mutliple/Address Fetching optimization. However, you need to specify the number of samples this is being applied to.
