Abstract

본 발명은 ATM 통신 방식의 외부 데이타 전송장치에 관한 것으로, 워크스테이션(10)으로부터 전송된 특정 어드레스신호를 디코딩하여 인에이블신호를 출력하는 어드레스디코더(12)와; 상기 어드레스디코더(12)에서 출력된 인에이블신호에 따라 외부로부터 전송된 데이타를 선택 출력하는 선입선출버퍼(14); 및 상기 선입선출버퍼(14)를 통해 출력된 외부 데이타 또는 상기 워크스테이션(10)의 주 메모리로부터 출력된 데이타를 ATM 셀의 유료 부하 공간에 매핑시켜 출력하는 AAL 처리 전송부(20)를 포함하여 구성되어, 워크스테이션(10)에서 외부데이타를 선택하는 특정 어드레스를 출력하면 외부데이타가 ATM 통신방식으로 BISDN을 통하여 전송되고, 워크스테이션(10)에서 주 메모리 데이타를 선택하는 어드레스 신호를 출력하면 주 메모리의 데이타가 ATM 통신방식으로 BISDN(50)을 통하여 전송됨에 따라, 워크스테이션의 주 메모리 데이타 뿐만 아니라 외부로부터 전송된 데이타를 ATM 통신방식으로 전송할 수 있는 것이다.The present invention relates to an external data transmission apparatus of an ATM communication method, comprising: an address decoder (12) for decoding a specific address signal transmitted from a workstation (10) and outputting an enable signal; A first-in, first-out buffer 14 for selectively outputting data transmitted from the outside according to the enable signal output from the address decoder 12; And an AAL processing transmitter 20 for mapping and outputting external data output through the first-in, first-out buffer 14 or data output from the main memory of the workstation 10 to the payload space of the ATM cell. When the workstation 10 outputs a specific address for selecting external data, the external data is transmitted through the BISDN in the ATM communication method, and when the workstation 10 outputs an address signal for selecting main memory data, As the data in the memory is transmitted through the BISDN 50 in the ATM communication method, not only the main memory data of the workstation but also data transmitted from the outside may be transmitted in the ATM communication method.
