Description
Claims (3)
- 마이크로 프로세서의 클럭주파수가 시스템 클럭 주파수의 내부 분할에 의하여 얻어지는 컴퓨우터 시스템의 제1 및 제2마이크로 프로세서(6,7)의 병렬 동기운전을 제공하기 위한 장치에 있어서, 장치는 제2마이크로 프로세서(7)의 클럭입력에 시스템클럭 신호통로를 개폐하기 위한 스위치(4)와 스위치(4)를 제어하는 논리회로(3)를 가지고, 회로(3)의 두개의 입력이 마이크로 프로세서(6,7)의 클럭출력에 접속되고, 그들의 입력간의 신호차에 대하여 논리회로는 스위치(4)가 시스템 클럭 신호통로를 끊게 하고, 한편으로 클럭출력의 동일한 신호에 대하여 그것은 스위치가 상기 통로를 만들게 하여, 한걸음씩 병렬동기성에 위상을 맞추는 것이 얻어지는 것을 특징으로 하는 병렬 동기 운전장치.
- 제1항에 있어서, 논리회로(3)는 부가 배타적인 OR회로를 가지고 그것에서 스위치(4)는 AND회로를 가지는 장치.
- 제1항에 있어서, 스위치(4)는 분할 산술회로(5)에 포함되고, 각각의 플립플롭에 할당된 마이크로 프로세서의 클럭입력과 시스템 클럭간에 접속된 제1 및 제2의 JK플립플롭을 가지고, 제2 JK플립플롭은 제2마이크로 프로세서(7)의 입력에 접속되고, 그의 J 및 K입력은 논리회로(3)의 출력에 접속되고, 이 JK플립플롭은 스위치(4)의 기능을 수행하는 장치.
