An HLS/DSP kernel comprises the Fast Fourier Transform LogiCORE IP instantiated in the HLS kernel using the HLS FFT library. Additionally, the kernel has the input and output wrappers for reading and writing data into and out of the FFT core. You can view the function call graph in the Vitis HLS GUI, as shown in the following figure.
