Abstract

본 발명은 멀티플렉서를 이용하여 영상의 프레임 데이타를 보다 정확하고 연속적으로 리드 및 라이트되는 동작을 수행하는 어드레스 선택장치에 관한 것으로, 이를 해결하기 위하여 매프레임 반전신호에 의해 동작되어 어드레스 생성부로부터 제공되는 각각의 리드 및 라이트용 어드레스 데이타 중 어느 한 어드레스 데이타를 선택하는 선택수단과, 이 선택수단에 의해 출력되는 라이트 및 리드용 어드레스 데이타에 따라 입력되는 프레임 데이타를 라이트하거나, 라이트된 프레임 데이타를 리드하여 디스플레이 장치로 제공하는 메모리 수단으로 이루어진다.The present invention relates to an address selection device for performing an operation of reading and writing frame data of an image more accurately and continuously using a multiplexer. Selection means for selecting any one of the read and write address data of each of the read and write address data, and write the frame data input in accordance with the write and read address data outputted by the select means, or read the written frame data. Memory means provided to the display device.
