Abstract
Description
Claims (1)
- 두 개 이상의 프로세서를 구비한 컴퓨터 시스템에 있어서, 프로세서의 어드레스 신호를 논리조합하여 듀얼 포트 메모리의 플래그 바이트 억세스시 플래그 어드레스 발생 신호를 발생하는 제1수단과, 버스 승인신호(BGACK)와 메모리 칩 선택신호(CS)에 의해 오프 보드 및 온 보드 프로세서로 상기 제1수단의 출력 행선지를 결정하고, 이 신호에 의해 인에이블되어 인터럽트 제어데이터가 제1상태일시 정보교환을 알리는 인터럽트를 발생하기 위한 제1 및 제2제어신호와 인터럽트 제어데이터가 제2상태일시 현재 수행중인 인터럽트를 해제하기 위한 제3 및 제4제어신호를 디코딩 출력하는 제2수단과, 상기 제2수단의 제1 및 제2 제어신호에 의해 온 보드 및 오프 보드의 프로세서로 정보교환을 알리는 인터럽트 신호를 발생하며, 제3 및 제4 제어신호에 의해 인터럽트 해제신호를 발생하는 제3수단으로 구성함을 특징으로 하는 회로.
