FIELD: data processing.
SUBSTANCE: invention relates to digital data processing and can be used for noiseless coding of data with variable correcting capacity in various systems for transmission or reception, as well as storage of data. Device includes adjustable registers configured for storage and distribution of coefficients of generating polynomial, shift registers configured for storage and distribution of control bits, and at least two stages, each having adders in a Galois field and AND elements.
EFFECT: creation of a parallel configurable coder of BCH (Bose-Chaudhuri-Hocquenghem code) codes, which makes it possible to encode under different characteristic of BCH codes during operation, allows adjustment of correcting capacity depending on purpose, and enables to process data coming into encoder in parallel, from a data bus, and to generate control information bits also in parallel form.
