| 术语 | bus-organized structure |
| 释义 | bus-organized structure 总线式结构;［汇流排式结构］ Structures used, generally, in microcomputers for the input／output of data and control information. Often in these bus systems, information can flow in both directions and, generally, more than one “talker” and “listener” share a single interconnecting wire. The voltage levels and impedances at the bus interface are set to allow rapid transmission of information to minimize errors due to interjected noise, and to allow a number of units to share the line without excessively loading the signal that is present. 常用于微型计算机中,实现数据和控制信息的输入输出的一种结构。在总线式系统中, 信息通常可以沿两个方向流动,多个发送设备和接收设备可共用一条总线。总线接口的电平 和阻抗应保证信息的高速传送,以尽量减少内部噪声干扰引起的差错,而且还要在不使当前 输出的信号过载的前提下,允许多个设备公用一条总线。 |
