Abstract
In a programmable digital arithmetic circuit, each input/output terminal of the necessary elemental circuit is connected via a matrix switches.in order to selectively constitute multiple types of basic digital arithmetic circuits that differ from each other. By turning on and off each switching element of the matrix switches, any one of the above-mentioned desired basic digital arithmetic circuits can be selectively constituted. Changing the functions is realized by a matrix switches and during the setting of the coefficients a purely physical coefficient value can be chosen so that a programmable digital arithmetic circuit that can be easily understand and handled by users will be constituted.
