Abstract
본 발명은 병렬 공통 버스형 고속 패킷 교환 시스템의 가입자 노드 입출력 정합 장치에 관한 것으로서, 가입자 입출력 장치를 비교적 저가인 동축 케이블을 사용하여 수백 미터 반경의 성형망을 구축하여 근거리 통신망이나 대형 통신시스템의 내부 연동망으로 활용할 수 있고, 폴링에 의해 중재하고 공통 병렬 버스를 통해 데이터 전달 교환을 이루는 비교적 간단한 매체 접근 프로토콜을 가지면서 320Mbps급의 고속의 성능을 내며 브로드캐스팅, 멀티캐스팅이 지원되며, 확장을 통해 192개까지 입출력이 가능한 병렬 공통 버스형 고속 패킷 교환 시스템의 가입자 노드 입출력 정합 장치를 제공하기 위하여, 시스템 버스 인터페이스부(10), 송신 패킷 메모리(11), 중앙 처리 장치(12), 메모리(13), 송신 DMA부(14), 태그 발생부(15), CRC 생성부(16), 다중화부(17), 송신 타이밍 제어부(18), 직렬 통신 송신부(19), 직렬 통신 수신부(20), 수신 타이밍 제어부(21), 역다중화부(22), 태그 분석부(23), 수신 DMA부(24), CRC 검출부(25), 수신 패킷 메모리(26)로 구성되어 비교적 저속의 저가격의 소자 및 메모리를 이용할 수 있는 장점이 있고, 병렬 공통 버스 기반의 패킷 교환 시스템을 통해 성형의 근거리 통신망이나 대형 통신 시스템의 내부 고속 연동망으로 활용할시 상호 일대일 통신, 멀티캐스팅, 브로드 캐스팅이 가입자 노드 상호간에 가능하며, 가입자 노드(3)의 통신처리 부하를 전용 가입자 입출력 정합 장치(9)에서 처리함으로 주제어 장치(7)의 부하를 경감하고 처리속도를 높일 수 있는 효과가 있다.The present invention relates to a subscriber node input / output matching device of a parallel common bus type high-speed packet switching system. It can be used as an interworking network, has a relatively simple media access protocol that mediates by polling and exchanges data transfers through a common parallel bus, delivering high speed performance of 320 Mbps, and supports broadcasting and multicasting. The system bus interface unit 10, the transmission packet memory 11, the central processing unit 12, and the memory 13 are provided in order to provide a subscriber node input / output matching device for a parallel common bus type high speed packet switching system capable of inputting / outputting up to Transmission DMA unit 14, tag generation unit 15, CRC generation unit 16, multiplexing unit 17, transmission other EMM control unit 18, serial communication transmitter 19, serial communication receiver 20, reception timing controller 21, demultiplexer 22, tag analyzer 23, receive DMA unit 24, CRC detector (25), the received packet memory (26) has the advantage of being able to use a relatively low-cost low-cost device and memory, and the internal high-speed of the local area network or large communication system through a parallel common bus-based packet switching system When utilized as interworking network, one-to-one communication, multicasting, and broadcasting can be performed between subscriber nodes, and the processing load of subscriber node 3 is handled by dedicated subscriber I / O matching device 9 so that the load of main controller 7 can be reduced. It can reduce the effects and speed up the processing.
