After a discussion of the reasons for choosing to implement logic in array form. a detailed description of the nature of array logic is given. Topics specifically discussed include general array structures and implementation, influence of decoder partitioning, design of logic arrays, output phase, “split” variables, feedback in logic arrays, and reconfiguration. Introduction Although there will...

We demonstrate a scalable and reconfigurable optical directed-logic architecture consisting of a regular array of integrated optical switches based on microring resonators. The switches are controlled by electrical input logic signals through embedded p-i-n junctions. The circuit can be reconfigured to perform any combinational logic operation by thermally tuning the operation modes of the swit...

On the basis of modularization of an optical parallel array logic system (OPALS), a new concept of an optical digital computer is considered. The OPALS is a parallel digital optical computing system using optical array logic capable of executing parallel neighborhood logical operations, or cellular logic. Modularizing functional elements in the OPALS, stability, reliability, and flexibility of ...

The paper describes how Constraint Based Reasoning (CBR) can be performed with two di erent paradigms, Constraint Logic Programming (CLP) and Array Based Logic (ABL). The author describes the operation of Constraint Logic Programming emphasizing CLP techniques for nite domain problems such as search strategies and consistency techniques. An explanation of Array Based Logic is presented includin...
