谈微机教学中数字电路的处理

Handling of the digital dectronic circuit in microcomputer course

微机类课程需要学生具备数字电路基础,但在许多微机类教材中并没有体现二者的关联。如果在微机课程教学中不能正确处理数字电路相关的内容,就会人为切断知识的延续性,加大学生理解的难度。本文从微机课程中的数字电子器件入手,并以“地址译码器”为例,阐述了数字电路在微机教学中的一个较好的处理方法。

Courses such as Microcomputer Science require students to be equipped with the basic knowledge of digital circuit. However there is no embodiment of the logic extension between the two aspects in all kinds of microcomputer textbooks. So if the contents of digital circuit are not to be flexibly dealt with, the continuing of the knowledge will be cut off, which will surely add to the student＇s difficulties in understanding. This thesis starts with the digital electric components in microcomputer course, and then takes the “sddress coder” as an example to expatiate the importance and necessity of flexible handling of the digital electronic circuit in microcomputer course.
