Abstract
본 발명은 ATM스위치의 자원을 공유하기 위하여 셀 다중화기를 두어 여러개의 프로세서가 동시에 한개의 ATM스위치 링크를 공유하여 ATM셀을 다중화하여 전송하는 ATM 셀 다중화 제어장치에 관한 것으로서, 각각의 프로세서 링크로 부터 수신된 ATM셀이 저장된 프로세서 송신 FIFO(303)와, 저장되는 셀 데이타를 제어하는 FIFO 콘트롤러(302)와, 각각의 프로세서 송신 FIFO(303)에 셀 데이타가 몇개 유효한지를 나타내는 셀 카운터(304), 셀 카운터로 부터 그 값이 1이상이면 셀 전송부로 셀이 유효되었음을 알리는 셀 전송 중재기(305), 셀 전송 중재기(305)로 부터 유효화된 프로세서 송신 FIFO(303)의 번호를 부여 받아서 셀을 전송하며, 셀 전송시 셀 간격 에러 발생시 프로세서 송신 FIFO(303)를 리셋하는 셀 전송부(306)을 구비한다.The present invention relates to an ATM cell multiplexing control device having multiple cell multiplexers simultaneously sharing one ATM switch link in order to share resources of an ATM switch, and multiplexing and transmitting ATM cells. A processor transmission FIFO 303 in which the received ATM cell is stored, a FIFO controller 302 controlling cell data to be stored, a cell counter 304 indicating how many cell data are valid for each processor transmission FIFO 303, If the value is greater than or equal to 1 from the cell counter, the cell transmission arbiter 305 and the cell transmission arbiter 305 receive the number of the valid processor transmission FIFO 303 from the cell transmission arbiter 305. And a cell transmitter 306 for resetting the processor transmission FIFO 303 when a cell interval error occurs during cell transmission.
