Programmable digital unit on semiconductor base - has logic system in arithmetic unit and instruction store and two result stores

摘要

The digital unit has a logic system(LV) which has two logic inputs(R,S), each of which is supplied by the output of an exclusive OR gate(EXOR I, EXOR II) with electrical digital pulses. Either one of the two logic inputs of the exclusive OR gates is loaded with control pulses by the central control unit(ST). The other input of the one gate is connected alternately to the data input(E) and to the output of a second result store(AKKU II) via a multiplexer(E-MUX). The output of the first result store(AKKU I) is connected to the other input of the second gate.
