| 摘 要： | 计算机采用补码运算,速度快效率高,但其递推公式推导复杂。补码乘法也是《计算机组成原理》课程的难点。文章从补码与真值的关系出发,首先推导出补码的右移公式,最终给出了二进制补码一位乘法规则的较全面的推导过程。

| Abstract: | The computer using two's complement is faster and more efficient,but the derivation of the rules about two's complement multiplication is Complex.Two's complement multiplication is also a difficulty of the course Principles of Computer Organization.This article starts from the relations of two's complement and the true value.First,it deduces a formula about the shifting to right of two's complement. Finally,it gives the detailed rules about two's complement multiplication. |
