摘要

Hardware-accelerated multicore clusters have recently emerged as a viable approach to deploy advanced digital signal processing (DSP) capabilities in ultra-low-power extreme edge nodes. As a critical basic block for DSP, Fast Fourier Transforms (FFTs) are one of the best candidates for implementation on a dedicated accelerator core; however, their peculiar memory access patterns make direct integr...
