While the term Super Sample Rate strictly means the processing of more than one sample per clock cycle, in the AIE context it is taken to mean an implementation using parallel kernels to improve performance at the expense of additional resource use.
In the FFT window, SSR operation is controlled by the template parameter TP_SSR. This parameter is intended to improve performance and also allow support of point sizes beyond the limitations of a single tile.
The parameter TP_SSR allows a trade of performance for resource use in the form of tiles used. The tile utilization is quite simply the same as the value of TP_SSR.
