Title: Information processor
Inventor: YAMAMOTO SADANORI
IPC: G06F13/24
Filed: 1990-03-27
Abstract: PURPOSE:To ensure the effective operation of a bus by attaining a constitution where an input/output controller discontinues the retransmission of an interruption request before the estimated waiting time shown in the statistic information elapses at reception of the report of the statistic information. CONSTITUTION:When an interruption request is transmitted to an arithmetic processor 20 from an input/output control part 30 via a common bus 10, the processor 20 reads the statistic information out of an internal storage part 22 via an informing part 23 when the acceptance of the interruption request is impossible. The statistic information shows the arithmetic processing information on that time point, i.e., the waiting time corresponding to the scale of an unprocessed program of a logic arithmetic part 21. The processor 20 sends the statistic information and the negative answer to the part 30. Then a reinterruption discontinuing part 31 of the part 30 starts to discontinue to discontinue the retransmission of the interruption request before the waiting time reported as the statistic information elapses. When the waiting time elapsed, the working of the part 31 stops. When the waiting time elapsed, the working of the part 31 stops. Then an interruption request is transmitted again to the processor 20 from the part 30.
