Abstract

본 발명은 정확한 인터럽트, 재시작 및 분기 삭제에 의한 데이타 종속, 데이타 반종속 및 순차성의 보전을 관리하면서 비순서적인 명령어를 실행하기 위한 슈퍼 스칼라 컴퓨터 아키텍춰 및 그 운영 방법에 관한 것이다. 범용레지스터에 참조되는 소오스 및 종착지 어드레스를 리네임하고 재순환하는데 복수개의 레지스터와 표가 사용된다. 범용 레지스터에 있는 종착지 데이타에 대한 엑세스는 데이타와 연관된 명령어가 모두 실행될 때까지 록된다. 소오스 및 종착지 레지스터 모두를 리네이밍시키는 것에 의하여, 입력 명령의 순서와 동일하에 명령어 결과를 소거함으로써 순차성의 보전을 유지하면서 반종속성 문제를 피할 수 있다. 상기 시스템 및 방법은 복수개의 입력 명령과 복수개의 실행 유니트로 동작한다. 소오스 및 종착지 레지스터의 리네이밍에 의해 생성된 상기 제어워드는 초기의 명령과 크게 다르지 않으며, 상태와 시퀀스 정보를 프로세서 제어워드에 부가하는 것을 피할 수 있다.
