Abstract

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 Structure(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 operations with thousands of data bits can be concurrently achieved in the DRS TOP with three partitions.
