Abstract
본 발명은 최종슬롯 상의 보드에서 출력되는 버스사용허가신호(BG0∼BG3)를 논리곱하는 게이트소자와, 상기 게이트소자의 출력에 따라 입력신호가 결정되어 시스템의 에러발생 신호(SYSFAIL)와 사용중신호(BUSY)를 각각 출력하는 게이트소자로 구성되어 임의의 보드에서 버스사용 요구신호가 출력되어 구동된 상태에서 상기 보드가 갑자기 사용요구신호를 취소해도 버스중재동작이 중지되지않는 컴퓨터의 버스중재오동작 방지회로.According to an embodiment of the present invention, a gate element multiplying the bus permission signals BG0 to BG3 output from a board on a final slot, and an input signal is determined according to the output of the gate element to generate an error signal (SYSFAIL) and a busy signal of the system. A bus arbitration prevention circuit of a computer in which a bus arbitration operation is not stopped even when the board abruptly cancels the request signal while the bus use request signal is output and driven from an arbitrary board. .
