<p>PURPOSE:To use only one timer even when a large amount of data are provided by registering a processing time corresponding to the processing of the forefront of a time waiting queue sequentially on the timer at every completion of a series of processing. CONSTITUTION:The time waiting queue 23 chained in order at the time of supplying corresponding to the data provided for terminal equipments (41-43) is generated. And the time is registered on a supplying time timer 22 corresponding to the forefront data of the queue 23, then, the arrival of the supplying time is waited. When the time arrives, the data to be provided is checked from the forefront of the queue 23 one by one, and corresponding data is read out from a magnetic disk device 2 to a main memory device 2, then, it is outputted to the equipments (41-43). When a series of processing is completed, the supplying time at the next time is counted, and it is registered on the queue 23 again, and registration on the timer is performed at the supplying time of the forefront data of the queue 23. Therefore, it is enough to perform the registration on the timer only for one time, thereby, no overhead in the timer is generated even when the number of processing to be handled is increased.</p> |
