FIELD: turbo-multipliers/inverted multipliers for radio communications. SUBSTANCE: first counter of address generator functions to count plurality of clock pulses, to generate first group count that initiates one of group addresses of multiplication block at each clock pulse, and to generate carry upon counting desired number of clock pulses; second counter receives carry from first counter, counts it, generates position count initiating one of position addresses in each group. Controller functions to control first and second counters. Operating device computes group count and position count using recursion formula and generates resultant bits. Buffer memorizes valid addresses formed from inverted bits received from bit inversion block and resultant bits accepted from operating device. EFFECT: provision for address generation during each desired period for turbo-multiplier/inverted multiplier. 12 cl, 7 dwg, 1 tbl
