Control Bus

定义 Definition

control bus:在计算机体系结构与数字电路中,控制总线指用于在 CPU、内存和外设之间传递控制信号的一组线路/通道,用来协调读写、时序与设备状态(如 Read/Write、中断请求、时钟、复位、使能等)。常与 data bus(数据总线)address bus(地址总线)并列讨论。

发音 Pronunciation (IPA)

/kntrol bs/

例句 Examples

The control bus tells the memory when to read or write.
控制总线告诉内存何时进行读或写。

During an I/O operation, the CPU uses the control bus to assert signals such as interrupt acknowledge and bus request, ensuring devices communicate in the correct sequence.
在一次输入/输出操作中,CPU 会通过控制总线发出诸如“中断响应”和“总线请求”等信号,以确保各设备按正确顺序通信。

词源 Etymology

control 来自法语 contrle,原指“核对、监管”,引申为“控制”。busomnibus(拉丁语“给所有人的”)的缩略,在工程语境中表示“多部件共享的一组公共传输通道”。合起来 control us 即“用于监管/协调系统动作的共享信号通道”。
