Abstract
시스템 보드의 종수를 줄일 수 있음은 물론, 간단한 구조를 가지면서도 하드웨어 디버깅을 쉽게할수 있는 교환 시스템의 프로세서 보드 이중화를 위한 듀얼 쓰기장치 및 방법이 개시된다. 그러한 장치 및 방법은 주 프로세서 모듈의 MPS버스와는 별도로 이중화 버스를 설치하고 그 이중화 버스를 통해 듀얼 쓰기를 행함에 의해 주 프로세서의 성능 저하를 방지하는 장치적 구조가 마련되며, 방법적으로 프로세서로부터 제공되는 데이타가 듀얼 쓰기이면 어드레스 및 데이타를 래치한 후 듀얼쓰기 시작신호를 버퍼를 통해 출력하는 단계와, 자기측의 듀얼쓰기가 완료시 상대측의 듀얼쓰기 완료인가를 체크하는 단계와, 상대측의 쓰기가 미완료시 다른작업을 수행하는 단계를 동작측에서 가지며, 상대측은 상기 듀열 쓰기 시작신호에 응답하여 상기 버퍼로부터 어드레스 및 데이타를 억셉트하고 메모리 요구신호를 발생하는 단계와, 메모리 쓰기작업의 완료 후 완료신호를 발생하여 전송하는 단계를 가진다.Disclosed are a dual writing apparatus and method for processor board duplication of an exchange system that can reduce the number of system boards, as well as simplify hardware debugging. Such an apparatus and method is provided with a device structure that prevents the performance degradation of the main processor by installing a redundant bus separately from the MPS bus of the main processor module and performing dual writes through the redundant bus. If the data to be provided is a dual write, outputting a dual write start signal through a buffer after latching the address and data; checking whether the dual write is completed on the other side when the dual write on the own side is completed; Has an operation of performing another operation when the operation is not completed, and the other side accepts an address and data from the buffer and generates a memory request signal in response to the duplication write start signal, and after completion of the memory write operation. Generating and transmitting a completion signal.
