3, but completes a DFT computation a factor of b times slower ... Note as well the Altera core doesn’t offer a 1296-point transform option and the outputs are not in normal order. Adding buffer ...

The synchronizer circuit will generate 1 value on Launch_pulse_en[0] and Capture_pulse_en[1] in such a way that the output of Wave Shaping Circuit is 1 for two functional clock cycles. As SCAN_EN=0, ...
