It further comprises a command buffer 22 for delivering the binary data stream to the CGI interpreter 23 CGI graphics processing apparatus as ranging. 호스트 CPU로 부터 시스템 버스를 통해 그래픽 명령을 받은 시스템 버스 인터페이스(1), 상기 시스템 버스 인터페이스(1)에 연결된 그래픽 프로세서(2), 상기 그래픽 프로세서(2)에 연결된 원도우 버퍼(4) 및 디스플레이버퍼(6)를 포함하고 있는 CGI 그래픽 처리 장치에 있어서, 초기 상태로 코맨드 버퍼를 엑세스하기 위한 플래그인 액세스 플래그를 오프로 세팅하여 어느 인터프리터의 접근을 방지하기 위한 제1단계, 상기 제1단계후 데이타를 바이너리 데이타 스트림으로 인코딩하여 상기 코맨드 버퍼 출력하는 제2단계, 상기 제2단계후 인코딩이 완료되면 상기 액세스 플래그를 온으로 하여 상기 인터프린터로 하여금 상기 코맨드 버퍼의 접금을 허용해 주고 다음 명령을 기다리는 제3단계, 및 상기 제3단계후 상기 인터플리터로 하여금 상기 코멘드 버퍼로 부터 바이너리 데이타스트림을 읽어서 디코딩을 행하도록 하는 제4단계로 구성된 것을 특징으로 하는 CGI 구현방법.A system bus interface (1) receiving graphics commands from the host CPU via a system bus, a graphics processor (2) connected to the system bus interface (1), a window buffer (4) and a display buffer connected to the graphics processor (2) A CGI graphics processing apparatus comprising (6), comprising: a first step for preventing access of a certain interpreter by setting an access flag, which is a flag for accessing a command buffer in an initial state, to be off, and data after the first step; (B) encoding a binary data stream to output the command buffer, and when the encoding is completed after the second step, turning on the access flag to allow the interprinter to engage the command buffer and wait for the next command. After the third step and after the third step, the interpreter attaches to the command buffer. And a fourth step of reading from the binary data stream to perform decoding. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
