Abstract
본 발명은 동영상 복호기에서 필요로 하는 프레임 메모리로 DRAM을 사용하는 동영상 복호기의 메모리 장치에 관한 것이다. 이에 따라 본 발명은 움직임 보상을 데이타와 전송된 차분 신호를 더하여 현재 프레임의 데이타를 복구하여 출력하는 신호 처리부와, 1 프레임분의 DRAM으로 구성되어 신호 처리부에서 처리된 데이타를 기록하고 기록된 데이타를 출력하는 프레임 메모리와, 프레임 메모리로부터 출력되는 데이타를 일시적으로 기록하며 움직임 보상을 위한 데이타를 신호 처리부로 출력하는 버퍼 메모리와, 프레임 메모리의 읽기, 쓰기 어드레스 및 버퍼 메모리의 읽기, 쓰기 어드레스를 생성하는 어드레스 생성부와, 신호 처리의 기본 단위인 매크로 블럭 단위로 데이타를 모아 소정의 구간동안 해당 매크로 블럭을 프레임 메모리로 출력하여 기록하는 버퍼를 포함하도록 구성된다.The present invention relates to a memory device of a moving picture decoder using DRAM as a frame memory required by a moving picture decoder. Accordingly, the present invention is composed of a signal processing unit for recovering and outputting the data of the current frame by adding the motion compensation data and the difference signal, and a DRAM for one frame to record the data processed by the signal processing unit and write the recorded data The frame memory to be output, the buffer memory for temporarily recording the data output from the frame memory and outputs data for motion compensation to the signal processor, and the read, write address of the frame memory and the read and write addresses of the buffer memory And an address generator and a buffer for collecting data in units of macro blocks, which are basic units of signal processing, and outputting and writing the macro blocks to the frame memory for a predetermined period.
