    Fast Fourier transform (FFT) is used in various applications such as signal processings and developing a high-speed FFT processor is quite required. In this paper, we propose a high-speed FFT processor based on selector logics. The selector-based FFT processor is constructed by focusing on the subtract-multiplication operations and partly applying selector logics to them. Furthermore, we implement the selector-based FFT processor on a Xilinx FPGA. Experimental results show that our proposed FFT processor can improve the processing speed by up to 21% and also reduce the number of LUTs by up to 33% compared with a naive FFT processor.
