Abstract

본 발명에 따른 그래픽 처리장치는 픽셀 데이타를 저장하고 있는 메모리(41); 지(z)값을 저장하고 있는 지-버퍼(43); 소정의 분할된 화면데이타를 저장하고 있는 데이타 스택 메모리(44); 디스플레이를 위한 데이타를 저장하고 있는 비디오 메모리(45); 상기 비디오 메모리(45)의 데이타에 따라 디스플레이하는 디스플레이하는 디스플레이장치(46); 및 상기 메모리(41)로부터 화면 데이타를 입력받아 소정 수의 화면으로 분할한 후 상기 데이타 스택(44)에 저장하고, 상기 데이타 스택(44)에 저장된 분할된 화면 각각에 대해 지(z)값을 비교한 후 최소의 지(z)값을 갖는 지(z) 데이타를 상기 지-버퍼(43)에 저장함과 아울러 각 픽셀에 대한 디스플레이 데이타를 형성하여 상기 비디오 버퍼(45)로 출력하는 그래픽 프로세서(CPU:42)로 구성되어 분할된 각 화면에 대해 지-버퍼 알고리즘을 적용하므로써 에일리에이징을 줄일 수 있어 화질이 개선되는 효과가 있다.The graphic processing apparatus according to the present invention includes a memory 41 for storing pixel data; A Z-buffer 43 which stores a Z value; A data stack memory 44 which stores predetermined divided screen data; Video memory 45 which stores data for display; A display device for displaying according to the data of the video memory 45; And receiving screen data from the memory 41, dividing the screen data into a predetermined number of screens, storing the screen data in the data stack 44, and assigning a z value to each divided screen stored in the data stack 44. After the comparison, the graphics processor which stores the Z data having the minimum Z value in the G-buffer 43 and forms the display data for each pixel and outputs it to the video buffer 45. By applying the Buffer algorithm to each divided screen composed of CPU: 42), it is possible to reduce the ageing, thereby improving the image quality.
