3.4.1.1. Using the Streaming FFT
When the data transfer is complete, the FFT deasserts sink_sop and loads the data samples in natural order.
Figure 11. FFT Streaming Data Flow Simulation Waveform
When the final sample loads, the source asserts sink_eop and sink_valid for the last data transfer.
Figure 12. FFT Streaming Data Flow Input Flow Control
- Deassert the system reset, The data source asserts sink_valid to indicate to the FFT function that valid data is available for input.
- Assert both the sink_valid and the sink_ready for a successful data transfer.
