GROUP STRUCTURE COUNTER WITH PRESERVATION OF NUMBER OF UNITS IN GROUPS Russian patent published in 2020 - IPC H03K23/40 G06F17/00 

FIELD: physics.

SUBSTANCE: invention relates to computer engineering. Technical result is achieved due to that the group structure counter with preservation of the number of units in the groups contains external input N bit data bus DI, external output N bit bus QO, group of G group counters 1₁, 1₂, …, 1_G, first group of G elements AND 2₁, 2₂, …, 2_G, group of G elements OR 3₁, 3₂, …, 3_G, inter-group hyphenation unit 4, external clock input CLK, external input G bit buses for enabling loading into EL groups, parallel counting of EP groups and consecutive counting of EC groups, external output of CO transfer. Each of group counters 1i (where i = 1, …, G) consists of (Ki) digits (where N = K1 + K2 +…+ KG) and contains (Ki) D-flip-flops 5₁, 5₂, …, 5_(Ki), transferring generator 6, group of (Ki) code generators with preservation of number of units 7₁, 7₂, …, 7_(Ki), group of (Ki) MX multiplexers 8₁, 8₂, …, 8_(Ki), OR element 9 and internal (Ki) bit bus of QT outputs of flip-flops.

EFFECT: technical result is reduction of hardware costs, faster operation and possibility of storing a given number of units in sets of consecutive states of the counter.
