New ContributorFFT IP Latency and obtaining unknown output data at first packet
This is streaming FFT IP parameters. The calculation latency and throughput latency are 1024 cycles.
As shown in screenshot below, one period of input sine wave is 1024 clock cycles. Could you explain the calculation latency and throughput latency in my case? When the output will be available? I am not sure about the definition of these latency.
During the first packet of the output, the values of source_real, source_imag, and source_exp are 'x'. Why is the first packet of output data missing?
