Abstract

본 발명은 전전자 교환기의 프로세서 모듈간 데이타 송수신방법 및 그 장치에 관한 것으로, 버스점유를 알리는 비트 스트림의 인지에 의해 데이타를 송수신하므로 오버헤드의 발생이 없이 데이타 송수신을 고속으로 할 수 있으며, 모듈간 별도의 버스 구성장치가 필요치 않아 소규모의 프로세서 모듈 접속시 경제적으로 데이타 송수신 할 수 있다.The present invention relates to a method and apparatus for transmitting and receiving data between processor modules of an electronic switchgear. Since the data is transmitted and received by recognizing the bit stream indicating the bus occupancy, data transmission and reception can be performed at high speed without generating overhead. There is no need for a separate bus component, so it is possible to send and receive data economically when connecting a small processor module.
