DEVICE FOR GENERATION OF MODULO-FIVE REMAINDER Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device has four units for calculation of basic symmetric boolean functions, twelve OR gates, two modulo-five adders, modulo-five subtracter, n inputs and three outputs. Inputs of device receives bits of input n-bit binary word X. Outputs of device output three-bit binary modulo-five convolution R = 4r₁+2r₉+r_s of input word X, where R X mod 5, , m 1, 3, and R (0, 1, 2, 3, 4} EFFECT: increased speed. 1 dwg, 4 tbl
