Abstract

The logical operation of binary input signals can be carried out with a programmable circuit arrangement. It contains a matrix (MA) of crossing data lines (DL) and coupling lines (KL) at whose coupling locations switching elements (KE) are arranged corresponding to a function table to be realized. The switching elements (KE) can assume three statuses: one status corresponds to a binary 1 and the second status corresponds to a binary 0; the third status corresponds to a binary 1 or to a binary 0. Every data line (DL) can be operated as input or as output with the assistance of a control signal (ST) that is supplied to an input circuit and to an output circuit (AG). The input signals coupled from the data lines operated as input onto a coupling line (KL) are subjected to an AND operation on the coupling line. By contrast, the signals coupled from the coupling lines (KL) onto a data line (DL) wired as output are subjected to an OR operation on the data line. Dependent on the statuses set in the switching elements (KE) in accord with a function table, various operations can be executed in that data lines (DL) are operated as input or as output.
