CFFT is a radix-4 fast Fourier transform (FFT) core with configurable data width and a configurable number of sample points in the FFT. Twiddle factors are implemented using the CORDIC algorithm, causing the gain of the CFFT core to be differen

FFT旋转因子，旋转因子是蝶形运算的组成部分，是数字信号处理FFT算法的基础部分-FFT twiddle factor, rotation factor is an integral part of the butterfly, digital signal processing is a fundamental part of FFT algorithm
