三值光学计算机模拟器的设计与实现

Design and implementation of ternary optical computer simulator

三值光学计算机(ternary optical computer, TOC)作为一种新体系结构的计算机,具有处理器位数众多且易扩展、位功能可重构、位可分组使用等特点,在海量或复杂数据的快速处理方面有很大潜力,但它的应用开发探索尚处于初期。为了扩展其应用范围,提出了一种基于三值光学计算机体系架构的模拟器TOCSim设计方案。该方案通过软件形式模拟TOC的运行过程,并在普通PC机上实现其雏形。TOCSim主要模拟TOC处理器的重构策略、处理器位的分配策略、中间结果解码以及运算效果模拟等过程。通过本模拟器的模拟效果图与TOC原型机上的运行结果光图进行对比,表明该模拟器的设计方案是正确的、可行的。

Ternary optical computer(TOC)is a new architecture computer with a large number of processor bits and the characteristics of easily scaling,reconfigurable bit functions,and groupable bits.It has great potential for fast processing of massive or complex data.However,it is still in the early stage of application development exploration.To expand its application,this paper proposed a TOCSim design scheme for a simulator based on a ternary optical computer architecture.It simulated the TOC operation process in the form of software and implemented its prototype on an ordinary PC.These operation processes mainly included the TOC processor reconfiguration strategy,processor bit allocation strategy,intermediate result decoding,and computing effect simulation.A comparison of the simulation effect graphs derived from the proposed simulator between the light graphs of the operation results on the TOC prototype shows that the design scheme of the simulator is correct and feasible.
