Abstract

본 발명은 디스플레이 화면상에 VGA 영상을 윈도우화하는 장치 및 방법을 제공한다. 이 장치는 VGA 제어기와, 래스터라이저 엔진(rasterizer engine)과, 디스플레이용 메모리(displayable memory) 및 비디스플레이어용 메모리(non-dispayable memory)를 갖는 프레임 버퍼를 포함하는 그래픽 어댑터이다. VGA 제어기는 프레임 버퍼의 비디스플레이용 메모리로부터 VGA 데이터를 저장, 처리, 검색하고 디스플레이 화면상에 VGA 영상을 윈도우화하는 등의 처리를 행하기 위해 이 데이터를 래스터라이저 엔진에 제공한다. 처리를 거친 후, 래스터라이저 엔진의 가속화 그래픽 프로세서는 나중에 디스플레이될 수 있도록 프레임 버퍼의 디스플레이용 메모리내에 있는 다른 그래픽 데이터 뿐 아니라 VGA 데이터도 저장한다.The present invention provides an apparatus and method for windowing a VGA image on a display screen. The device is a graphics adapter including a VGA controller, a rasterizer engine, and a frame buffer having a displayable memory and a non-dispayable memory. The VGA controller provides this data to the rasterizer engine for processing such as storing, processing, retrieving VGA data from the non-display memory of the frame buffer, windowing the VGA image on the display screen, and the like. After processing, the rasterizer engine's accelerated graphics processor stores the VGA data as well as other graphics data in the display buffer's memory for display later.
