Abstract

PURPOSE:To improve the input/output processing throughput by inhibiting the input/output processing start for a certain period of time from the time point when the release of the busy mode conditions is reported from an input/output device or an input/output controller. CONSTITUTION:A controller tape of a main memory MSU 108 stores the time point when the release of the busy mode conditions is reported via an input/ output device DEV 107 which is controlled by a microprogram or an input/ output controller CU 105. When a channel processor CHP 102 starts the input/ output actions to the CU 105, a register is selected out of the contents of a control table of the MSU 108 and the inhibited time is recognized. Then it is decided whether the input/output actions can be started or not to the CU 105 based on the difference between the present time point and the time point when the busy mode conditions are released. As a result, the proper input/output processes can be started to both the CU 105 and the DEV 107.
