二进制补码两位乘算法分析

Analysis of algorithm of binary two -bit based multiplication

在计算机二进制补码一位乘法的基础上，依据校正法和Ｂｏｏｔｈ算法的基本公式，推导出补码两位乘法的两种算法公式，根据公式得到补码两位乘法的操作规则，并且对推导出的两种算法进行了分析．最后给出两种算法的计算举例．

According to the formula of correction and Booth algorithm, two formulas and operation rules of two bit based complement multiplication algorithm on the base of one bit based complement multiplication algorithm is given, and the two algorithms are analyzed. At last an example for the two algorithms is explained.
