Summary: This paper systematically elaborates the key theories and technologies of parallel computing for the Ternary Optical Computer (TOC). Through a programming platform, experiments are carried out to show the effectiveness and feasibility of the present theories and technologies. The results demonstrate the significant advantages of TOC over traditional computers in terms of clock cycles and computing resources.

Summary: In this paper, a fine-grained fast parallel genetic algorithm based on a ternary optical computer is proposed. The algorithm, demonstrated by solving the traveling salesman problem, takes advantage of the parallelizability and power-efficient characteristics of ternary optical computers. The theoretical analysis and experimental results show that the proposed algorithm performs efficiently as the size of the problem increases, providing a theoretical foundation for the application of ternary optical computers in data-intensive computing.

Summary: The study proposes bitwise square rooting of MSD numbers and floating numbers on a parallel carry-free modified signed digit (MSD) adder. It presents parallel square rooting for single and multiple MSD integers on a ternary optical computer (TOC) processor, showing that the efficiency of square rooting for big data can be greatly improved.

Summary: In this paper, a novel radix-2 Montgomery modular multiplier and architecture for high speed and low ATP implementation are proposed. The use of SSDA and a detecting and skipping mechanism effectively reduce the number of addition rounds, leading to higher speed and lower hardware cost.

Summary: In addition to word-level weight pruning, recent studies have shown that bit-level weight pruning is highly effective in accelerating neural network computation without sacrificing accuracy. This work proposes a transformation technique, a shortest path problem formulation, and a novel acceleration architecture to overcome the limitations of bit-level weight pruning. Experimental results demonstrate significant reductions in essential bits and inference computation time.
