Method and apparatus for interrupt processing in a computer system having peripheral units connected in a daisy chain

摘要: An interrupt processing method and an apparatus provides end indicative information storing unit for of a daisy chain at least one plurality peripheral units, the receiving when receives acknowledge signal but does not output request signal, outputs specific state to central unit, so that is returned from response waiting state. Therefore, error produced by noise, etc., delay reduced. Further, connection cut optional portion irrevelant ignored, efficiency improved.
