Study Of A Cordic Based Radix-4 FFT Processor
Abstract-This paper focuses on the study of FFT and IFFT of pipelined based radix-4 algorithm and to proceed this
algorithm it uses a butterfly structure method.Due to the use of radix-4 instead of radix-2 technique, computation speed gets
doubled. To proceed further, Butterfly structure i.e. BFI and BFII can be executed using the DFT algorithm.Twiddle factor
multipliers (TFM) can be implemented using Co-ordinate Rotation Digital Computer (CORDIC) algorithm,there are other
units like delay units and control units for them we use FSM based design.
