CLEANING OF SEGMENTED CONVEYOR FOR WRONGLY PREDICTED TRANSITIONS

摘要

FIELD: information technologies.;SUBSTANCE: processor conveyor is segmented into an upper part, prior to commands that follow not in a program order, and one or more lower parts downstream the upper part. The upper conveyor is cleaned after detection of the fact that the transition command was wrongly predicted, minimising delay in selection of commands from a target address of the right transition. Lower conveyors may continue execution until the command of the wrongly predicted transition is confirmed, besides, at this moment of time all non-fixed commands are cleaned from the lower conveyors. Existing mechanisms of conveyor cleaning elimination may be used with the help of adding the identifier of the wrongly predicted transition, at the same time complexity and cost of hardware for lower conveyors cleaning are less.;EFFECT: increased efficiency of processor.;16 cl, 2 dwg
