The top-level HLS/DSP kernel, fft_2d, contains two sub-functions: fft_rows and fft_cols. Each sub-function contains the individual HLS/DSP kernels which perform MAT_COLS and MAT_ROWS point FFT respectively.

The PL-based data movers consist of the dma_hls kernel, which generates impulse input and checks the output of each FFT stage for the expected pattern.
