Abstract

본 발명은 다중루프를 이용한 어드레스 계산장치로서, 시스템 제어기로부터 입력되는 로드신호에 의해 구동하여 미리 설정되어 있는 초기값에 따라 각각의 루프를 순차적으로 실행시킨 후 제로검출 종료신호를 출력하는 다중루프회로 (100)와 ; 어드레스 오프셋 신호에 의한 상기 다중루프회로 (100)의 제로검출 종료신호를 각각 선택하여 출력하는 멀티플랙서 (200); 상기 멀티플랙서 (200) 에서 선택하여 출력된 신호를 가산한 후 시스템제어기의 램에 출력하여 필요한 어드레스를 계산하게 하는 가산기 (300)로 구성되어 필요한 어드레스를 계산하게 한 것이다.
