Abstract
A digital controlling device in which arithmetic operations are executed under control of a predetermined program on the basis of an input signal obtained from at least one detector in a section to be controlled to generate a driving signal, said driving signal being sent to actuating means in said controlling section. Said digital controlling device comprises a plurality of calculation specification tables for respectively describing therein an operation type for each arithmetic element, storage addresses of input/output data for said each arithmetic element, and storage addresses of operation parameters for the each arithmetic element; a calculation sequence table for describing therein the number of arithmetic blocks and addresses used for reading-out of associated said calculation specification tables corresponding to said arithmetic elements in an order that arithmetic operations are to be executed in said digital controlling device, said calculation sequence also being a total arithmetic element number at its leading address; data tables for respectively describing therein data in the corresponding address zones specified in said calculation specification tables; and a processing program section for executing said operation elements in said order described in said calculation sequence table and reading data necessary for said execution from said data tables on the basis of associated said calculation specification tables.
