2.3 Fast Fourier Transform

Fast Fourier Transform (FFT) is on of the most common signal processing algorithms.Table 2-3 shows a 1024-point single precision floating point complex FFT execution time on Arm-Cortex-A53. The benchmark on Arm-Cortex-A53 uses the implementation from Ne10 library, which leverages the Advanced SIMD or NEON acceleration of Cortex-A53. This library is not included in the SDK but can be downloaded from the official Ne10 repository.
