摘要
本文给出了微机存储器扩展和 I/O接口装置中关于地址编码的一种系统化设计方法。该方法的核心是建立一个各 I/O器件和存储器件的地址表 ,并根据地址空间的分配来设定与每一个器件相关的每一根地址线的逻辑电平。地址表使硬件设计人员清楚明了各硬件的地址安排 ,给硬件系统的设计带来很大方便。本文还给出了数据线、控制信号线以及地址编码的设计规则 。
A systematic technique to the design of the address coding for expanding the microprocessor memory and I/O interface devices is given. The core of this method is to build a address table for a variety of I/O devices and memory, then according to the assigned address space, the logic levels on the corresponding each address line for every device are set up. The address table makes designers understood in the address location for a variety of hardware. Also, this paper presents a rule for the designing of data lines, control signal lines and address codings. It brings hardware system design convenience. The technique is also a useful analysis tool.
