BTB를 이용한 분지명령어처리

Abstract

BTB(Branch Target Buffer)가 파이프라인 프로세서에서 분지예측을 행함으로써 분지명령어의 성능저하를 줄이는데 효율적으로 사용될 수 있음은 여러 논문에서 확인되었다. 이 논문에서는 그러한 단점을 줄이기 위해 상호보완적인 기법을 제시함으로써 BTB를 최적으로 활용할 수 있도록 하였다.

A Branch Target Buffer(BTB) can reduce the performance penalty of branches in pipelined processors by predicting the path of the branch and caching informations used by the branch. Currently several branch prediction strategies based on the BTB are proposed, but each strategy has some defects. Thus we propose a combined technique using BTB information.
