The considered case study for this tutorial is a real-time system comprising:
128 parallel signals, at a
125 MSa/s sample rate each, with
CINT16 datatype (16 bits for the real part and 16 bits for the imaginary part) for both twiddle factors and data.
The total required I/O bandwidth, thus minimum throughput, is thus 16 GSa/s or 64 GByte/s.
