Revenchuk I. Аlgebro - logic methods of description of arithmetical ratios and their application for creation of rational structures of calculators.

The thesis solves the problem of development of аlgebro - logic methods of description of arithmetical ratios which are used for creating rational structures of calculators. New methods of mathematical description of arithmetical operations of m-digital codes with the use of systems of equations of finite predicates algebra are developed. A parallel combinational logical substructure for solving arithmetic problem of finite-predicate algebra which is used to create structure of a "widely parallel combinational logical structure + satellite processors + an operator machine" is created on the basis of these method. A computer variant of a computational-reference programme which permits to quicker realize any mathematical calculations of any complexity is created and implemented on the basis of algebro-logic methods and algorithmical system developed.
