This tutorial illustrates these concepts by designing a PFA-1008 transform in Versal using both AI Engine and PL elements working cooperatively. The PFA approach mcan apply here since 1008 = 7 × 9 × ...
A 1D fast Fourier transform (FFT) implements on the AI Engine array using a 2D FFT algorithm with higher efficiency overall. This "divide & conquer" approach provides a better solution because it ...
