PARALLEL UNIT COUNTER Russian patent published in 2021 - IPC G06F7/38 

FIELD: computing technology.

SUBSTANCE: invention relates to a parallel counter. The counter is comprised of seven EXCLUSIVE-OR elements and two AND elements, wherein the first, second inputs of the i^th and the output of the j^th EXCLUSIVE-OR elements are connected with the first, second inputs of the i^th AND element and the second input of the (j+1)^th EXCLUSIVE-OR element, respectively, and the first input of the fourth EXCLUSIVE-OR element is connected with the fifth input of the parallel unit counter, wherein additionally introduced thereto are five majority elements, the (j-2)^th input of the k^th majority element, the second input and the output of the first AND element are connected with the (j-2)^th input of the (k+2)^th, the input of the seventh and the first input of the second EXCLUSIVE-OR elements, respectively, and the output of the (j-2)^th, the output of the (i+3)^th majority elements and the outputs of the sixth, i^th EXCLUSIVE-OR elements are connected with the (6-j)^th input of the seventh, the i^th input of the i^th EXCLUSIVE-OR elements and the first, (i+1)^th outputs of the parallel unit counter, respectively, the (j-2)^th, fourth, sixth, seventh, eighth, ninth and fourth inputs whereof are connected with the (6-j)^th input of the third, the third input of the fourth, the third, first inputs of the fifth, the third, first inputs of the sixth EXCLUSIVE-OR elements and the output of the second AND element, respectively.

EFFECT: simplified configuration of a parallel unit counter.
