Abstract. In this paper, we focus on the M-k -B addition of the form M þ B 1 þ B 2 þ : : : þ B k based on an optical approach, where M is a modified signed-digit number and B i 's are the binary numbers. We present three transforms C, P, and R and an algorithm of carry-free parallel addition of M and B. Based on these transforms, the accumulation computing M-k-B is proposed which indicates that it requires only 2k steps to complete the addition in parallel. Then, the optical structures for C, P, and R transforms as well as the adder realizing M þ B are designed. Moreover, a photoelectric implementation of the ternary optical adder to realize M-1-B structure using the reconfiguration method is presented. Additionally, an optical experiment for 2-bit M-2-B ternary adder is carried out to demonstrate the feasibility of M-k-B adder. The work indicates that the parallel carry-free addition in form M 0 þ B 1 þ B 2 þ : : : þ B k is easily completed.

“…In 2000, Jin et al [1] proposed the concept of and structures for a ternary optical computer (TOC), in which information is represented using three optical states-two polarization directions of the light that are orthogonal to each other plus a third state denoting total darkness, and optical processors can be constructed using basic elements such as liquid crystal and polarizers. In 2007, the decrease-radix design principle was proposed by Yan et al [2] during the construction of a 360-bit experimental TOC system.…”

This paper discusses the principles, structures, and implementation procedures for reconfiguring a ternary optical processor (TOP). Typical structures, classifications, and naming of the TOP and basic operation units (BOUs) are described in this paper. The circuit implementations, commands, and processes for the reconfiguration are also discussed in detail. A simple analysis of the high performance and low power consumption of ternary optical computers is presented. Finally, an experiment is performed on reconfiguring a 1-bit BOU, which shows that the principles of reconfigurable TOPs are valid, and that the implementations and commands for the reconfiguration are effective.Keywords ternary optical processors (TOPs), reconfigurable processors, decrease-radix design principle, basic operation units (BOUs) CitationJin Y, Wang H J, Ouyang S, et al.

“…As we have seen in recent reports, most experimental devices proposed possess only a few bits with singleton design for each arithmetic unit, therefore, the way of designing would always be at designer's will what is called as informality or randomness. Up to now, since the year of 2000, we have had a number of years of experiences in studying the ternary optical computers [6][7][8][9] , and have not only designed a dozen of ternary logic optical arithmetic units but also implemented some parts of them [10][11][12][13][14][15] . Similarly, in the design of these units we met the same issues of informality which became a big obstacle to prevent us from constructing a practical hundreds-bit of ternary optical computer.…”

In this paper a new theory referred to as the decrease-radix design (DRD) is proposed, which is found in the research of logic units of ternary (tri-valued) optical computer. Based on the theory proposed, the principles and the regulations of the DRD for making operation units of multi-valued operation with carrying/borrowing free are also presented. The research work has come to the following important conclusion: let D be a special state contained in n physical informative states, then one may figure out any multi-valued processors within n (n×n) carrying/borrowing free n-valued units by the composition some of n×n×(n−1) simplest basic operating units according to the regulations of DRD proposed in this paper. The detailed systematic way of our design regulations is highlighted step by step in the paper with an example of design of a tri-valued logic optical operating unit. The real architecture, the procedure, and the experimental results of our sample in tri-valued logic operating unit are given. Finally, a re-constructible model of ternary logical optical processor is introduced. The theory proposed in the paper has laid down a solid foundation for the design of re-constructible carrying/borrowing free operating units in ternary optical computers and can be widely used as the designing reference in a variety of multi-valued logic operating units.carrying/borrowing free operating units, decrease-radix design, re-constructible, ternary optical computer
