FIELD: information technologies.
SUBSTANCE: method includes the following: detecting in the first stage of the branch forecasting system that BTAC record complies with instruction of conditional branching; detecting in the first stage of branching direction on the basis of the specified record in BTAC; detecting in the second stage of branch forecasting system that the record complies with the specified instruction of conditional branching; modification of status information complying with the specified record, corresponding to the specified instruction of conditional branching, after call of instruction of conditional branching and prior to permit of the conditional branching instruction; and control of record into BTAC on the basis of the modified status information.
EFFECT: increased efficiency due to reduced probability of problem occurrence in several cycles of cleaning.
