The FFT Library is a computational library for Renesas MCUs.
FFT (Fast Fourier Transform) is a fast algorithm for implementing discrete Fourier transform. This FFT library also uses assembler tuning to realize highly efficient processing for Renesas MCUs.
The FFT enables the user to measure the frequency characteristics of the input data. For example, by executing the FFT on voice data, you can measure the amplitude (volume) of each frequency that comprises the sound.
