A circuit for the synchronization of the operating cycles of a digital arrangement with an external clock signal which arrangement includes a calculating unit and a circulating store which must produce a sequence of coefficients in a predetermined order at each cycle. The circuit has switching means for circulating the coefficients in the store either in series or word-by-word, means for producing a word clock, means for forming operating cycles synchronous with the word clock and for starting each operating cycle at each characteristic transition of the external clock signal appearing after the end of each cycle. The switching means are controlled to have the sequence of coefficients circulate in series once in each cycle and for having the coefficients circulate word-by-word for the remaining period of time. |
