Notes to
(1) In the burst I/O data flow architecture, you can specify the number of engines in the FFT MegaWizard interface. You may choose from one to
(2) Transform time is the time frame when the input block is loaded until the first output sample (corresponding to the input block) is output.
(3) Block throughput is defined as the minimum number of cycles between two successive start-of-packet (sink_sop) pulses.
