FIELD: information technologies. ^ SUBSTANCE: method is carried out by development of a multi-channel serial Viterbi decoder, comprising the following functional units, interrelated to each other: an input buffer, a generator of a data word reading signal from the input buffer, a decoder of a data word command field, a unit of channel parameter registers, a unit to process a command "path metrics nullification", a unit to process a command "setting a value of the specified path metric", a unit to process a command "reading a bit from a path with the specified number", a unit to process a command "processing of input counts", a main memory of decoding paths and path metrics, a unit to generate a basic address of the main memory area of decoding paths and path metrics for the current decoding channel, a unit to generate an address of the main memory cell of decoding paths and path metrics and a unit of registers of decoding channels output data. ^ EFFECT: provision of the possibility to treat coded units of the final length for designs of the following types - terminated, truncated, circular ones. ^ 3 cl, 3 dwg |
