This AI Engine kernel implements the DFT-9 using a similar approach to the DFT-7 kernel above. This kernel requires 3 compute tiles and 1 combiner tiles and operates in a manner very similar to the DFT-7 kernel. I/O transforms are transmitted in alternating fashion over two streams as above. The first two compute kernels are 100% efficient, whereas the third tile is only 25% efficient. The graph for this AI Engine kernel is shown below.
