A '''synchronous circuit''' is a [[circuit]] in which the parts are synchronized by means of a [[clock]] subcircuit. |
|||
⚫ | |||
In a synchronous circuit, every change in the logical levels of its components is simultaneous. The commutations follow the level change of a special synchro signal, called "clock". No matter how long may be a logical chain, there are no delays between the clock and the other parts' logical transitions, so the behaviour of the whole circuit -in any point- can be foreseen exactly at any speed. |

在实际的电路中,时钟源到达各个寄存器的线网长度不同,因此需要使用一些时钟缓冲器来尽量降低[[时钟偏移]]的影响。 |
