Abstract: A device and a method for FFT(Fast Fourier Transform) are provided to offer a simple binary reverse output order, reduce complexity, and minimize the number of hardware elements by using a structure formed with only the adders without any multiplier, as a mixed radix 4-2 butterfly structure is used. The first butterfly operation module(130) generates four first output data by performing a radix-4 butterfly operation from input data and data received from the first feedback memory(120). The first multiplexer(140) outputs the data from the first feedback memory or the first output data to the first output port. The second multiplexer(150) stores the input data or the data excluding the data output from the first multiplexer among the first output data. A controller(190) makes the first and second multiplexer provide the first output data to the first output part according to the simple binary reverse output order.
