| 术语 | bus driving circuits |
| 释义 | bus driving circuits 总线驱动电路;［汇流排驱动电路］ The special circuits that are added to a computer bus. When information can be supplied to the bus from more than one source, the circuits must be used to select and control the output from each source so that they don't interfere with each other. Basically, the bus drivers are designed to ensure electrical compatibility between each of the sources connected to the bus and to control the connectionsand disconnections of sources from the bus. They also multiplex the information onto the bus. 附加在计算机总线上的一种特殊电路。当来自多个源的信息提供给总线时,该电路必须 对每个源的输出进行选择和控制,以避免它们相互干扰。从原理上讲,总线驱动器的设计应 保证与总线相连的各个源间的电特性兼容,并能控制各个源与总线的连接和断开。它们也能 进行信息的多路选择,以使某一信息送上总线。 |
