Summary:Disclosed is a method for performing tile-based rendering in a graphics processing device, which includes the steps of: receiving a first draw call used for rendering a first tile of a preceding frame; receiving a second draw call used for rendering a second tile of a succeeding frame corresponding to a position of the first tile; generating a signature of the first draw call and a signature of the second draw call; comparing the signature of the first draw call with the signature of the second draw call; and rendering the second tile by using a rendering result of the first tile according to a comparison result. Accordingly, the present invention can improve the performance of the graphics processing device. 선행 프레임(preceding frame)의 제 1 타일의 렌더링에 이용되는 제 1 드로우콜을 수신하고, 제 1 타일의 위치에 대응되는 후속 프레임(succeeding frame)의 제 2 타일의 렌더링에 이용되는 제 2 드로우콜을 수신하고, 제 1 드로우콜의 서명(signature) 및 제 2 드로우콜 서명을 생성하고, 제 1 드로우콜의 서명과 제 2 드로우콜의 서명을 비교하고, 비교 결과에 따라 제 1 타일의 렌더링 결과를 이용하여 제 2 타일을 렌더링하는, 그래픽스 프로세싱 장치에서 타일-기반 렌더링을 수행하는 방법이 개시된다.
