| 术语 | microcomputer bus |
| 释义 | microcomputer bus 微(型计算)机总线;［微电脑汇流排］ An electrical connection that serves as a communication path between the components of a system. Some microcomputer systems use at least three type of buses: local, intersystem, and intrasystem. The local bus connects the microprocessor and support chips, while the intersystem bus provides communication between the complete system and the outside—the peripheral devices or other systems. Between the local and intersystem devices is the intrasystem bus, often called simply the “system bus”, which provides the communication link between the boards that comprise the microcomputer system. 一种为系统各个部件之间提供通信路径的电气连接。有些微机系统至少使用三种总线:局部 的、系统间的和系统内的。局部总线连接微处理机与附属芯片,而系统间总线提供整个 系统与外部即外设或其它系统之间的通信。系统内总线则介于以上二者之间,常简称为系统总线,它提供构 成微机系统的各电路板之间的通信链路。 |
