| 摘 要： | 从两个二进制补码数相加和的符号和溢出性的判断方法入手，针对多个二进制数同步超前进位加法，定义了模2^k M补码编码方案，提出了判断其加法和的符号和溢出性的方法，并进行了相应的证明．最后，就模2^k M补码编码方案的实施进行了论述．该方案的提出为开发利用同步超前进位加法、转变微处理器的传统运算设计方案和提高计算机的计算速度提供了重要的理论依据．

| Abstract: | Referring to the method of judging the sum symbol and overflow of two binary complement code numbers ' addition, a mod 2k+M complement code scheme, and is defined a method of judging the symbol and overflow of the result about several binary numbers' synchronous look-ahead carry addition, is brought forward which is proved. Finally how the scheme is applied is discussed. The scheme provides an important theory to develop and make use of the synchronous look-ahead carry addition, transform the traditional operation design scheme of processor,and heighten the computing velocity of computer on it. |
