BACKUP COUNTER FOR GENERATING TIME MARKS Russian patent published in 2010 - IPC H03K21/40 

FIELD: physics; computer engineering.

SUBSTANCE: invention relates to computer and pulse engineering and can be used in designing highly reliable backup systems for counting and processing digital information. The device consists of m channels, each with a control unit, an n-bit counter, a unit of n majority decision elements, a majority decision element, a monostable multivibrator, a multiplexer, a digital comparator, a first, second and m^th shift register, a slave counter, programmable memory, first and second decoders. A random failure occurring during operation in any channel of the backup counter will be countered in time T (input pulse period) by restoring correct information in each of the n-bit counters (5). The device is significantly simplified due to cutting on the number of elements providing inter-channel communication and amount of converted information.

EFFECT: simple circuit design of the device.
