Elements of a Digital Photonic Computer

The paper covers a variant of architecture development of digital photonic computers. Along with quantum computers, they are one of the possible ways to overcome the crisis of computing performance. The data processing implementation in digital photonic computers at terahertz frequencies potentially provides the performance exceeding by two or more decimal orders of magnitude the performance of the most modern computing systems. The elements of digital photonic computer architecture described in the paper are focused on solving a wide class of computationally time-consuming problems in the paradigm of structural calculations. The problems of ensuring the performance and accuracy at solving problems on the developed digital photonic computer, as the processing rate should correspond to the data receipt rate, are considered. The synchronization and switching subsystem was designed and analyzed by the authors. At the synthesis (programming) stage, it forms a computational structure and provides both static and dynamic coordination of data flows in calculations.
