I need some resources about the FFT/IFFT optimization, especially the implementation using FPGA/Altera.
Hi Montardar Abas Taher, here is the optimized 2-point FFT model. We can use this to implement n-point FFT.

appreciated, thank you very much. If you have more, please provide to me.
This IFFT/FFT (link below) was written in VHDL (I used it for Xilinx-FPGA but without using IP-Cores or Xilinx specific components so you can also use it for Altera).
Goal was to reach a high data throughput/data rate with some limitations in computation accuracy. So a parallelized structure was used. If speed is no problem but computation accuracy more important you can use "in-place" calculations with radix-2.
