摘要
计算机补码表示法是计算机相关原理的重要知识点,更是计算机运算方法乃至运算器设计的基础.采用类比法,结合日常生活中的实例和计算机硬件特点,从"模"的概念入手,依次从补码概念的引入、补码的性质、由补码求真值的方法和引入补码的真正意义四个方面对计算机补码的概念进行了探究.
Complement code is not only the important knowledge of computer related course teaching,but also is the foundation of computing methods and designs.In this paper,using the analogy method,combining with the daily life examples and computer hardware characteristics,start off with the concept of ＂mode＂,vividly analyzed from four perspectives of introduction of complement code in computer,the property of the complement number,the method of getting truth-value from complement number and the true meaning of introducing the concept of complement code in a computer to further explored.
