PROCESSOR, COMPILER AND PROCESSING METHOD FOR DYNAMIC CONDITIONAL BRANCH FOR REDUCING PIPELINE CONTROL HAZARD

摘要

PURPOSE: A processor for reducing pipeline control risk, a compile apparatus, and a dynamic condition branch process method are provided to reduce pipeline control risk without adding hardware by correcting condition branch prediction. CONSTITUTION: A branch prediction code executor(110) predicts condition branch with reference to suggestion information for branch prediction in a branch prediction code. A test code executor(120) evaluates condition branch prediction for an optional branch prediction test. The test code executor records prediction success information.
