8253定时/计数器计数过程的实验研究
EXPERIMENTAL STUDIES ON THE COUNTING PROCESS OF 8253T/C
【摘要】 基于清华大学计算机工厂生产的TPC— 1型微机实验系统 ,提出一个探究 82 53计数过程的实验方案 .通过实验结果分析 ,指出了部分教材在对 82 53方式 3计算过程的表述中所存在的问题
【Abstract】 Based on the experimental system of TPC-1 manufactured by the computer plant of Qinghua University,the article raises an experimental plan which aims to make an exploration into the counting process of 8253 T?C.Experimental results analyses indicate that,in some textbooks intended for students of computer science,problems are existent in the expression of the third method of the counting process of 8253 T?C.
