The DSPLib contains one FFT/iFFT solution. This is a single channel, decimation in time (DIT) implementation. It has configurable point size, data type, forward/reverse direction, scaling (as a shift), cascade length, static/dynamic point size, window size, interface api (stream/window) and parallelism factor. Table Header Format lists the template parameters used to configure the top level graph of the fft_ifft_dit_1ch_graph class.
