ABSTRACT:
A multi-level priority interrupt system is used for controlling the access of input/output control devices to a host computer which is connected to the devices and controls their operation. The input/output control devices each of which is contained on a different LSI chip, output different levels of interrupt requests to the host computer. During operation, each input/output control device outputs an interrupt signal of a frequency determined by a level of an interrupt to be sent to the host computer. The interrupt signal is supplied from one external terminal of the input/output control device. Upon receipt of the interrupt signals, the host computer determines a priority of the interrupt from the frequency of the signal and then executes a corresponding interrupt routine.
