Abstract
본 발명은 본 발명은 피시(PC)의 시스템 메모리 제어장치에 관한 것이다.The present invention relates to a system memory controller of a PC.
종래 PC의 메인메모리 제어장치는 메인 메모리와는 별도로 비디오 메모리를 구비되어야만 디스플레이 할 때마다 비디오 제어부에서 메인 메모리와는 상관없이 비디오 메모리를 액세스 해야하기 때문에 비디오 메모리의 용량을 늘리기 위해서는 또 다른 비디오 램을 추가해야만 하는 문제점이 있었다.In order to increase the capacity of a video memory, a main memory controller of a conventional PC must have a video memory separate from the main memory, and the video controller must access the video memory regardless of the main memory every time it is displayed. There was a problem that had to be added.
따라서 본 발명은 상기한 종래기술의 문제점을 개선코자하여 PC의 시스템 메모리의 가장 상위의 일정한 부분을 비디오 메모리화 하고 비디오 제어기와 시스템 메모리 사이에 다중화기를 설치하여 비디오 신호를 처리하도록 하므로서 비디오 메모리를 제거하도록 한 것이다.Accordingly, the present invention eliminates the video memory by improving the above-mentioned problems of the prior art by converting the upper part of the system memory of the PC into a video memory and installing a multiplexer between the video controller and the system memory to process the video signal. I did it.
