Abstract

PURPOSE:To decide the task executing form of an arithmetic processor based on the priority level of the task by designating the reinterruption frequency to a field in a reinterruption permission command code which is produced to an input/output controller from the arithmetic processor. CONSTITUTION:A peripheral input/output controller IOC 4 performs the transfer of data between a main memory MEM 3 and an input/output device according to an action command code given from an arithmetic processor EPU 2. An interruption is applied to the EPU 2 as an action end report for the transfer of data, etc., by an interruption command code. Thus the EPU 2 produces a reinterruption permission command code including a field showing the reinterruption frequency to the IOC 4. Thus the IOC 4 kept under an interruption holding state performs the reinterruptions to the EPU 2 based on the reinterruption frequency and accepts the reinterruptions according to the priority level of a task. As a result, the task executing form of the EPU 2 is decided based on the task priority level.
