摘　　要：针对三值光计算机进行逻辑运算时处理器的数据位与像素位在数量对应关系上的差别,提出了一种新的典型光路结构——双旋光器结构来提高光学处理器的重构速度,减少数据位数的管理难度。利用提出的结构实现了以行为单位的运算单元——行运算器,讨论了行运算器的重构特性、重构电路以及重构指令。在此基础上,设计并实现了可以降低处理器管理软件复杂度的双旋光三值光学处理器,并阐述了双旋光三值光学处理器的重构过程。最后,进行了行运算器重构指令的验证实验。验证结果表明:双旋光三值光学处理器原理正确,81个重构指令全部有效;在具有3个分区的双旋光三值光学处理器中,可并行实现任意千位量级的二元三值逻辑运算。To eliminate the difference between data bits and pixel bits of the processors in a Ternary Optical Computer（TOC） in the logic operation, a new typical optical structure, Double Rotator Struc- ture（DRS）, was proposed to improve the reconfiguration speeds of the optical processors and reduce the difficulty of managing a large number of data bits. The operation unit based on the DRS was used to achieve one line＇s function of the truth table in the logic operation, and it was called Line Calculator （LC）. The reconfigurable features, circuit implementations, and reconfigurable commands for the LC were discussed in detail. Then, the DRS Ternary Optical Processor（TOP） was designed and achieved to reduce the complexity of the processor management software. Finally, a verified experiment of reconfigurable LC was performed, which shows that the principles of DRS TOP are correct, and all 81 commands for the reconfiguration are effective. Moreover, each of the two input, three-valued logic opera- tions with thousands of data bits can be concurrently achieved in the DRS TOP with three partitions.
