Abstract

PURPOSE:To realize a response to the interruption request of an input/output device with an optional priority and at the same time carry out the processes of many interruption factors, by providing the signal lines for read of interruption requests. CONSTITUTION:When an interruption request occurs from input/output devices 2-1-2-n, a CPU1 detects this request via a signal line 4 and delivers the interruption reception signal to a signal line 5 when the reception is possible. On the contrary, an input/output device makes each proper bit position significant after detecting the reception of interruption and transmits the bit position to the line 4. The CPU1 reads the data of signal line to identify the input/output device that gave an interrpution request. When detecting plural significant bits, the CPU performs a decision of priority to one of input/output devices and at the same time makes a signal line significant. In response to the significant signal of the line 6, the input/ output device received a priority transmits the significant signal to a signal line 3. The CPU1 reads the data of the line 3 to start an interruption process in accordance with the interruption factor.
