Abstract
본 발명은 어드레스 확장 장치에 관한 것으로, 종래에는 데이타버스를 이용하는 시스템에서 엠버스와 에스버스 및 시스템버스로 사용하는 브이엠이버스등으로 구성되어 에스버스를 접속할 때 버스 넓이의 차이로 제어영역의 제한이 발생하여 시스템의 성능을 저하시키는 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an address expansion device. In the related art, an address expansion device is conventionally composed of an embus, an esbus, and a vbus used as a system bus. There was a problem that the limitation caused the performance of the system.
본 발명은 상기와 같은 문제점을 감안하여 데이타버스를 사용하는 시스템에서 에스버스와 브인엠이버스를 직접 접속할 때 에스버스의 어드레스를 확장 레지스터의 사용으로 확장하여 어드레스버스로의 액세스할 때 아양한 제어영역 확보로 시스템의 성능을 향상하는 효과가 있다.SUMMARY OF THE INVENTION In view of the above problems, the present invention provides various controls when accessing an address bus by extending the address of the bus with an extension register when directly connecting the bus and the bus bus in a system using the data bus. Securing the area has the effect of improving the performance of the system.
