Abstract

본 발명은 퍼스널 컴퓨터에서의 한글처리장치에 관한 것이다. 본 발명은 한글 처리시 폰트 데이타 비디오 메모리에 기록하는 경우 CPU를 경유하지 않고 직접 비디오 메모리에 기록하므로, CPU에 걸리는 부하를 감소시킬 수 있어 퍼스널 컴퓨터의 성능을 향상 시킬 수 있다. 또한, 한글 폰트 출력속도를 종래보다 10배 정도 향상 시킬 수 있으므로 한글 처리를 고속으로 수행 할 수 있다.The present invention relates to a Hangul processing apparatus in a personal computer. In the present invention, when writing to the font data video memory during Hangul processing, the data is written directly to the video memory without passing through the CPU, thereby reducing the load on the CPU and improving the performance of the personal computer. In addition, the Hangul font output speed can be improved by about 10 times compared to the conventional one, it is possible to perform Hangul processing at high speed.
