- 망동기 장치 내에 클럭발생부의 발진 클럭으로부터 분주한 클럭을 입력하여 밀리세컨드(msec) 단위의 시각 데이터를 직렬로 발생하는 카렌더 칩으로 구성되는 시스템 시각 데이터 발생부가 다중화 구조로 이루어져 시스템 클럭 관리부의 제어에 의해 중앙처리장치로 시각 데이터를 공급하는 교환시스템의 시각정보 정확도 향상방법에 있어서,상기 시스템 클럭 관리부에 시각 데이터 요구가 들어오면 상기 중앙처리장치에 인터럽트를 발생시키는 과정과,상기 인터럽트가 발생되면 상기 중앙처리장치는 상기 시스템 시각 데이터 발생부의 카렌더 칩으로부터 발생되는 시각 데이터를 읽은 후, 상기 시각 데이터를 직렬로 공급받는 과정으로 이루어짐을 특징으로 하는 교환시스템의 시각정보 정확도 향상방법.
- 제 1항에 있어서,상기 다중화 구조로 이루어진 시스템 시각 데이터 발생부는 각각에서 상기 시각 데이터를 직렬로 발생함을 특징으로 하는 교환시스템의 시각정보 정확도 향상방법.
