Fast Fourier transform (FFT) is a basic algorithm in digital signal processing and has been widely used in engineering, science and mathematical calculation. With the wide application of ARMv8 processor, it is more and more important to study FFT algorithm to realize high performance on ARMv8 platform. In the current open source FFT library, FFTW packages are mainly suitable for ARMv8 platform, while FFTW and FFTs packages are mainly suitable for ARMv7 platform. This paper implements and optimizes FFTs software package on ARMv8 platform, making it suitable for ARMv8 processor. The experimental results show that the performance of FFTs is improved by about 18% compared with FFTW in ARMv8 platform.
