PRESENTATION OF CYCLE TRANSITIONS IN TRANSITIONS PREHISTORY REGISTER USING MULTIPLE BITS

摘要

FIELD: information technology.;SUBSTANCE: method involves: determination that conditional branch instruction is the branch instruction of cycle termination; counting total number of cycle iterations, which cycle has been terminated by means of cycle termination branch instruction; saving multidigit value in branch history register (BHR), where this value specifies total number of cycle iterations, after cycle termination; and indexing the table of branch prediction unit (BPT) using at least BHR after cycle termination to obtain branch prediction for cycle termination branch instruction. In this method branch prediction is based at least partially on history of branches.;EFFECT: improvement of processor performance and saving power.;27 cl, 4 dwg
