Abstract
PURPOSE: To increase the high speed and reliability of computer, by preventing the occurrence of system down so that the response signal can not be returned to the control unit if the response signal is produced in error from the input and output unit.
CONSTITUTION: The data are received and given between the control unit 12 of the computer 12 and the input and output unit, and the response of it can be confirmed at the response signal line 28. When the unit 12 designates the sixth input and output unit and it is stored in the address FF24, the response signal is returned from the unit 11 only when the unit 12 outputs the address signal and the sixth address number. With the unit 12 not outputted, if the response signal is produced in error, the response signal is not returned to the unit 12. Thus, the high speed and reliability of computer can be increased with the prevention of the production of system down.
