These FFT stages are really no different than any other decimation in |
frequency FFT, save only that the coefficients are alternated between the |
434,7 → 441,7
line high in addition to the output values {\tt o\_left} |
(the first of two), and {\tt o\_right} (the second of the two). |
\item Ever after, whenever {\tt i\_ce} is high, the FFT core will clock |
two samples in and two samples out. On any valiid first |
two samples in and two samples out. On any valid first |
pair of samples coming out of the transform, |
{\tt o\_sync} will be high. Otherwise {\tt o\_sync} will |
remain low. |
