DEVICE FOR MODULO ADDITION AND SUBTRACTION OF NUMBERS Russian patent published in 2000 - IPC

FIELD: automation and computer engineering, in particular, for computers operating in multiple-stage residual classes. SUBSTANCE: goal of invention is achieved by introduced first tabular automaton, second tabular automaton, third tabular automaton, first binary adder, first AND gate, second AND gate, OR gate, NOT gate, second binary adder and second decoder. Device provides comparison of parity of input operands and subsequent analysis of parity of additive modulo operation result. EFFECT: increased functional capabilities due to possibility to implement modulo taking operations for m<m1m2, where m is device modulo, m1 and m2 are two modulo factors of device. 1 dwg, 5 tbl
