摘　　要：在微机应用系统中,总是通过总线实现CPU与外部存储器、I/O接口部件进行信息储存和交换。然而, 在系统设计时,人们往往忽视总线的驱动和平衡能力,结果易导致系统整体性能的下降。介绍了总线直流负载 和交流负载的估算办法,也为解决单向总线和双向总线的负载驱动及平衡问题提出了具体的解决方案。In microcomputer application system, the bus is usually used to realize information memory and exchange between CPU and external memory or between CPU and I/O interface. In the design, the ability of bus driving and balancing are usually ignored, so that the performance of the whole system is fallen. The estimate method of DC load and AC load based on the bus in microcomputer application system is introduced. The load driver and the balance of single direction and dual direction bus are focused.
