FIELD: automatic control and computer engineering; modular arithmetic. SUBSTANCE: device has five-table computer, second and third OR gate units 6 and 7, first second, third, and fourth AND gate units 14, 11, 15, and 12, modulo-constant adding units group 21, first and second residue code determining units 2 and 9, complementary residue code determining unit 17, first and second operand index determining units 3 and 10, operant index inversion determining unit 8. Functionally completed part of full arithmetic table is used to find intermediate result of modular operation followed by its correction by using extended meaning of operand index. EFFECT: reduced hardware quantity. 1 dwg, 5 tbl øøø1
