A action in which peripheral controls regulate the transfer of data between the central processor and peripheral devices. Specifically, they reconcile the mechanical speeds of the peripheral devices with the electronic speed of the central processor, and minimize the interruption of central processor activity due to peripheral data transfers.; 外圍控制器調(diào)整中央處理器與外圍設(shè)備之間的數(shù)據(jù)傳送的工作過程。特別是這些控制設(shè)備使 得中央處理器的電子速度與外圍設(shè)備的機械速度協(xié)調(diào)起來,把由于外部數(shù)據(jù)傳輸造成的中央處 理器活動的中斷降低到最少。
