DATA DECOMPRESSION DEVICE Russian patent published in 2018 - IPC H03M7/30 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer technology and is intended for use in information processing systems. Device comprises input data register 2, multi-output prioritizer 3, group of N data switches 4₁, 4₂, …, 4_N, group of L registers 5₁, 5₂, …, 5_L, output buffer 6, NOR element 7, first OR element 8, second OR element 9, D flip-flop 10, as well as input data bus 1, external outputs 13, external synchronization input 11, external synchronous unit input, zero state 12, internal data bus D, symbol mask bus M and symbol group indicator bus U and w groups of N digit indicators of most significant unit S1, S2, Sw. Wherein data input bus 1 comprises ID data input digits, which consist of w symbols of k digits, input N digits of symbol mask IM and input L digits of IU symbol group indicators (L is number of groups of w symbols from k digits, where N=L*w).

EFFECT: broader functional capabilities in terms of the ability to restore compressed data and easy implementation.
