BRANCH PREDICTOR FOR SETTING PREDICATE FLAG TO SKIP PREDICATED BRANCH INSTRUCTION EXECUTION IN LAST ITERATION OF LOOP PROCESSING

摘要

A processor simultaneously issues instructions to multiple threads in a same instruction execution cycle. An instruction issuer controls issuance of an instruction for each of the multiple threads. A detector detects, for each of the multiple threads, whether a loop processing is currently being executed. A unit causes the instruction issuer to increase a number of instructions to be issued when the detector detects that the loop processing is currently being executed.
