Similarly, modify the configuration of the FFT parameters to meet the new design requirements.
The following table shows the modified FFT parameters:
TP_CASC_LEN splits the FFT/iFFT operation over multiple kernels in series, placing each subsequent kernel on an adjacent tile to achieve higher throughput. Per the design requirement, the target is to achieve 2000 MSPS. To get this result, set it to 3.
TP_API is set to stream type interface port.
TP_PARALLEL_POWER is set to 1. If it is greater than 0, TP_CASC_LEN applies to the subframe FFT rather than the FFT as a whole. TP_PARALLEL_POWER improves performance and supports point sizes beyond the limitations of a single tile.
