发明名称 MODULO ADDITION AND SUBTRACTING DEVICE
摘要 FIELD: automatics, computer engineering. SUBSTANCE: modulo addition and subtraction device is inserted with second 15, third 16, fourth 28 and fifth 29 units of AND gates, converter 17 of code of number to additional modulo code, first 26 and second 22 converter of code of number Xto code X, converter 21 of code of number x to code [X/x], second ring shift register 27, second 25 and third 23 decoders, table computer 24, OR gate 37, second counter 35, second NOT-OR gate 36, second inhibition gate 34, third AND gate 32, differentiating network 33 to increase speed of response. Characteristic feature of invention lies in decrease of each operand by K times and after determination of result it is increased by K times with subsequent correction depending on ratio Ato B(A, B are operands). Thanks to it number of cycles necessary for realization of modulo operation decreases. EFFECT: increased speed of response. 1 cl, 1 dwg
