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

FIELD: automation and computer engineering. SUBSTANCE: device may be used for computers and control equipment operating in residual class system. Device has two groups of OR gates, three ring shift registers, size AND gates, differentiating circuit, seven AND gates, four OFF gates, encoder, decoder, unit of OR gates, two NOT gates, two counters, two NOR gates, OR gate, converter of integer into [X/k] code, converter of code of integer X into code of X mod k, converter of integer code to additional modulo code. Goal of invention is achieved by decreasing each operand K times and, when result is calculated, increasing it k times and correction depending on ratio of A mod k and B mod k, where A and B are operands. EFFECT: decreased number of cycles for implementation of modulo calculation operation. 1 dwg
