摘要

提出了一种生成正则符号位数的新方法。该方法计算简单，速度快。此外，还提出了CSD数的二进制表示，称为二进制编码CSD (BCSD)数。证明了BCSD数在相同大小的数据字中唯一地表示其等价的2的补码数。此属性允许在不添加额外空间的情况下将数字转换为其本身。提出了一种将2的补数直接转换为等价的BCSD的算法。

A new method for conversion of a 2's complement to canonic signed digit number system and its representation

A new technique is developed to generate canonic sign digit numbers. The technique is shown to be computationally simple and fast. In addition, a binary representation of CSD numbers, known as binary coded CSD (BCSD) number, is also presented. It is shown that a BCSD number uniquely represents its equivalent 2's complement number in the same size data-word. This property allows conversion of the number onto itself with no extra space added. An algorithm is developed to directly convert a 2's complement number to its BCSD equivalent.
