Design And Implementation Of Ternary Optical Processor Control Circuit

In2000the Ternary Optical Computer (TOC), a new kind of computer, is proposed by our research team in China. With the supports of the National Science Foundation of China and the211Leading Academic Discipline Project, a lot of achievements which all with self-owned intellectual property have been gained. Now, the research of our team is in a leading place in the world by more than a decade of hard work. In2005the first TOC experiment system which proved the TOC principles was built and in2007the second system which proved the structures was built too in Shanghai University, China. Since2010a new experiment system, SD11(abbreviation for Shanghai Daxue2011, Daxue is the Chinese pronunciation of University), has being developed in Shanghai University. SD11will offer an experimental platform to researchers who are interested in application software and algorithm, and it will be the first optical-electronic hybrid computer which can be programmed by using high level program language. In SD11, a key subsystem is the ternary optical processor control circuit. This subsystem is intensively investigated in this dissertation.The design goals of the optical processor control circuit are to control thousands of data bits of TOC in parallel and to reconstruct each data bit into a specific processor through hardware. Based on the first two experiment systems and the decrease-radix design principle, with the help of the existing data bits management theories, the author has investigated the hardware technique of reconfigurable optical processors, designed the corresponding control circuit and achieved the basic hardware of managing and addressing the many data bits. The results of author’s research are focused on that an integrated control circuit of TOC’s optical processor is implemented. Soon afterwards some experiments have been done to reveal the effectiveness of the design schemes, and to illustrate the validness of the circuit.The main contributions in this paper are as follows: 1) A layer control policy is proposed for the SD11’s optical processor.By the policy, the complexity of hardware design of the TOC’s optical processor which has many data bits is efficiently reduced. So, the layer policy is the key factor to complete this research work, and is the cornerstone to build further TOC’s optical processor.2) Hardware of reconfigurable ternary optical processor is developed successfully.This achievement has improved the hardware-based reconstruction theory and technology of TOC’s optical processor and advanced the TOC to a new stage of application research.3) A hardware support for the many data bits management theory is achieved.This achievement has provided a practice circumstance for improving and founding the data bits management theory.
