为了提高三值光学计算机的存储与转换效率,该文提出1种把N位改进的有符号数(MSD)转换成N位标准二进制数的串并混合转换方法。基于此转换方法利用偏振片、液晶、分光器、反射镜、译码器和光电管等光电器件设计了硬件转换器逻辑结构。使用转换器SD11可以直接以标准二进制形式输出结果,从而使存储效率提高50%,同时实现MSD数据转换硬件化。
In order to improve the storage and conversion efficiency of ternary optical computers , a serial and parallel hybrid method is presented for converting N bits modified signed digit (MSD) into N bits standard binary data .The logic structure of a hardware converter is designed using polarizers , liquid crystals ,optical splitters , mirrors, decoders and photoelectric tubes and so on based on the conversion method proposed here .The result can be output in standard binary data using a converter SD11a,nd the storage efficiency is improved by 50%,and the hardware implementation of MSD trans -formation is realized .
