Abstract

끼워넣기 처리중에도 수정을 할 수 있도록 한다.
전자장치(10)에는 CPU1,RON2, RAM3 및 입력수단(4), 다시 데이타 버스(5) 및 어드레스 버스(6)가 설치된다. 또한 수정할 곳의 어드레스의 레지스터(7)와 수정 끼워넣기 벡터의 레지스터(8)가 설치되어, 이들이 데이타 버스(5)에 접속된다.
다시 이 레지스터(7)에 기억된 어드레스와 어드레스 버스(6)의 어드레스와 일치를 검출하는 비교기(9)의 출력부가 CPU1의 끼워넣기 제어부 X에 접속된다. CPU1에는, 다른 처리로부터의 끼워넣기 제어부 A,B,C...로 설치되어 있다, 다시 입력수단(4)에는 외부기억장치(20)가 접속되어, 이 외부기억장치(20)로 부터의 주프로그램의 불비를 수정하기 위한 정보는 입력수단(4)을 통해서 RAM3에 기억됨과 함께, 이 RAM3에 레지스터(7및 8)에 기입된 데이타를 퇴피시키는 스택 에어리어(32)가 설치된다.
