FIELD: computer equipment.
SUBSTANCE: invention relates to the field of computer equipment, in particular to data processing devices, and can be used for construction of automation equipment and functional units of control systems, as well as for processing results of physical experiments. Device for detecting boundaries of on-bit range contains N-bit input bus D, output bit QR of LSB number and output bus QL of number of high-order bits, containing M bits, where M=]log2 (N+1)[(greater integer), a group of (N-1) OR elements 11, 12, …, 1(N-1), a group of (N-1) elements NOR 21, 22, …, 2(N-1), first 31 and second 32 counters of lower ordered units, as well as internal shift bus SR to the right and internal shift bus SL to the left, which contain N digits.
EFFECT: technical result of the invention is broader functional capabilities in terms of determining boundaries of a on-bit range.
