Fast Fourier Transform (FFT) is a multiply accumulate heavy building block in many applications. Table 3-4 shows a 1024-point single precision floating point complex FFT execution time. The Arm Cortex-A53 benchmark uses the implementation from Ne10 library, which leverages the Advanced SIMD or NEON acceleration of Cortex A53.
