The discrete Fourier transform (DFT) converts N complex values from the time domain to the frequency domain. The fast Fourier transform (FFT) is an optimized algorithm designed to compute the DFT efficiently. The STM32F10x DSP library provides a complex radix-4, with decimation-in-time, linear-order FFT. Let x[N] be the time signal samples. 0. The 32k limit is the binary limit as opposed to the RAM limit - there is no guarantee that the binary for performing the real FFT will be smaller than the complex FFT. In reality it could be a more optimized algorithm that is more complex, so that it might require less ram / CPU cycles to compute but could still require more (cheaper.
