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

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering and is intended for use in information processing systems. Said result is achieved by the fact that device comprises N D1, D2, ..., DN input symbols by k bits connected to input data register 1, first group of N OR elements 2₁, 2₂, …, 2_N, first group of N AND elements 3₁, 3₂, …, 3_N, multi-output priority unit 4, NOR element 8, synchronous D-trigger 9, (N-W) bit register 10, data switches unit 11, output buffer 12, as well as external input C of synchronization 15, external input CLR of asynchronous setting to zero state 14, external outputs Q of device 16, as well as an internal data bus DD of N symbols with k digits, a group of W internal buses of high symbol indicators U1, U2, …, UW, internal N bit mask bus M and internal N bit bus BR, wherein the data switch unit includes W switches 11₁, 11₂, …, 11_w, and multi-output priority unit includes W cascades 4₁, 4₂, …, 4_w, wherein each i-th cascade 4_i (i=1, 2, …, W, where W is the number of output symbols), contains a group of (N-1-i) OR elements 5_i1, 5_i2, …, 5_{i (N-i-1)}, group of (N-i) inhibition elements AND with one inverse input 6_i1, 6_i2, …, 6_{i (N-i)} and group of (N-i) AND elements 7_i1, 7_i2, …, 7_{i (N-i)}.

EFFECT: wider range of tools for the same purpose.
