DEVICE FOR UNPACKING DATA Russian patent published in 2020 - IPC H03M7/30 

FIELD: computer equipment.

SUBSTANCE: invention relates to computer engineering and is intended for use in information processing systems, as well as in compression and decompression units without losses in systems for rational use of storage and transmission devices, processing of physical experiment data. Device comprises an input data register RD, a multiple-output priority unit FU, a group of N data switches with k digits, group of N registers by k digits with synchronous input R of setting to zero state, output buffer BQ, element NOR, N groups of k elements 2AND, register of common mask RM1, D-trigger with synchronous input R of setting to zero state, switch of KM mask, register of current mask RM2.

EFFECT: reduced bit depth of input data and ease of implementation with simultaneous increase of information capacity without loss of information due to reduction of required amount of memory for storage of sequence of groups of input data of binary symbols and corresponding symbols masks.
