METHODS AND DEVICE FOR ENSURING CORRECT PRE-DECODING Russian patent published in 2010 - IPC G06F9/30 

FIELD: information technology.

SUBSTANCE: method involves defining a granule which is equal to the smallest length instruction in the instruction set and defining the number of granules making up the longest length instruction in the instruction denoted MAX. The method also involves determining the end of an embedded data segment, when a program is compiled or assembled into the instruction string and inserting a padding of length MAX-1 into the instruction string to the end of the embedded data. Upon pre-decoding of the padded instruction string, a pre-decoder maintains synchronisation with the instructions in the padded instruction string even if embedded data are randomly encoded to resemble an existing instruction in the variable length instruction set.

EFFECT: ensuring reconstruction during repeated synchronisation owing to reduced errors of synchronising the mechanism for pre-decoding the instruction string.
