Abstract

FIELD: computer engineering. SUBSTANCE: device has shift register, group of comparators, group of multiple-bit delay gates, adder, group of triple-input adders, group of NOT gates. Information input of shift register serves as information input of computing unit. Input of first bit of shift register is connected to first inputs of comparators, second input of i-th comparator is connected to output of (i+1)-th bit of shift register, i = 1, . . ., N-1, where N is amount of numbers to be sorted. Output of i-th comparator is connected to i-th input of adder and to first input of i-th triple input adder through i-th NOT gate. Input of first multiple-bit delay gate is connected to output of adder. Second input of i-th triple-input adder is connected to output of (i-1)-th triple-input adder through i-th multiple input delay gate. Clock pulse input of computing unit is connected to clock inputs of shift register and multiple input delay gates. Outputs of adder and triple-input adders provide outputs of computing unit. In addition device has (N-1) groups of single-bit delay gates, output of i-th NOT gate is connected to input of (N-i)-th group of delay gates, which contains (N-i) single-bit delay gates, which are connected in series. Output of i-th group of single-bit delay gates is connected to third input of i-th triple-input adder. Clock inputs of all single-bit delay gates are connected to clock pulse input of device. EFFECT: introduced (N-1) groups of single-bit delay gates result in simplified design.
