bus driver
总线驱动器;［汇流排驱动器］
Generally refers to a specially designed integrated circuit that is added to the data bus system to facilitate proper drive to the CPU when several memories are tied to the data bus line. Such circuits are required because of capacitive load ing that slows down the data rate and prevents the proper time sequencing of microprocessor operation.
一种专门设计的集成电路,附加在微处理器的数据总线上,为中央处理器提供足够的驱动 能力,使其能通过总线连接多个存储器。如果没有它,电容性负载将降低数据传送速度,并破 坏微处理器的正常操作时序。 |
