Claims (2)
- 한번에 어느 하나만이 유효하게 되도록 각각 리셋트입력(R)을 갖춘 적어도 2개의 프로세서장치(1,2)가 버스(4)를 매개하여 공통으로 접속되어 구성된 시스템에 있어서, 상기 각각의 프로세서장치(1,2)에 의해 셋트/리셋트되는 적어도 한 개의 모우드설정용 플립플롭(31)을 갖추고, 이 모우드설정용 플립플롭(31)이 지시하는 동작모우드에 따라 대응하는 오직 한 개의 프로세서장치(1 또는 2)이 리셋트를 해제하고, 이 리셋트가 해제된 오직 한 개의 상기 프로세서장치가 다른 프로세서장치와 공통으로 사용하고 있는 상기 버스(4)를 전용으로 사용하도록 하는 것을 특징으로 하는 프로세서간 결합방식.
- 제 1 항에 있어서, 상기 모우드설정용 플립플롭(31)이 지시하는 내용에 따라 대응하는 오직 한 개의 프로세서장치의 리셋트를 해제하도록 된 게이트 회로수단(32,33)과, 상기 프로세서장치에 의해 모우드가 절환될 때 상기 모우드설정용 플립플롭(31)에서 발생되는 상태변화를 검출하는 회로수단(35,36) 및, 이 회로수단(35,36)에 의해 검출된 출력을 근거로 하드웨어 자원에 대해 일정시간동안 초기화신호를 발생시켜 출력하도록 된 플립플롭 회로수단(37)을 갖추어, 상기 프로세서장치에 의한 모우드절환시에 리셋트를 해제시켜 해당 프로세서장치를 초기상태로부터 활성상태로 할 때는 상기 공통 하드웨어자원도 함께 초기와시키는 것을 특징으로 하는 프로세서간 결합방식.
