- 영상신호 처리장치의 어드레스 발생회로에 있어서, 외부 메모리의 영역에 각각의 시작 어드레스를 저장하는 인덱스 레지스터부와, 미 복원된 영상 데이타를 상기 외부 메모리에 저장하고 저장된 영상 데이타를 상기 메모리로부터 리드하기 위한 어드레스를 발생하는 입력신호 처리부와, 움직임 보상시 사용되는 참조 어드레스에 대한 정보를 발생하며 움직임 보상이 완료된 영상 데이타를 상기 외부 메모리에 라이팅하기 위한 어드레스를 발생하는 움직임 보상처리부와, 복원된 영상데이타에 따라 화면상에 디스플레이할 데이타를 리드하기위한 어드레스를 발생 디스플레이 처리부와, 상기 입력신호 처리부 및 움직임 보상 처리부와 디스플레이 처리부로부터 발생되는 각각의 어드레스를 인가되는 선택신호에 따라 다중화하는 멀티플렉서와, 상기 멀티플렉서로부터 출력되는 선택된 어드레스를 수신하여 최종 어드레스 및 상기 외부 메모리에 영상 데이타를 리드 및 라이트하기 위한 메모리 제어신호들을 생성하는 메모리 인터페이스를 가짐을 특징으로 하는 회로.
- 제1항에 있어서, 상기 메모리 제어신호들은 행 및 열 스트로브 신호를 포함하는 것을 특징으로 하는 회로.
