Abstract
PURPOSE: To make it possible to perform a corresponding control operation even in case of the mixture of use request, while performing the processing in the alternate buffer system when both buffer memories can be reserved in a memory management routine, and executing transfer by using one buffer memory when only one buffer memory can be reserved.
CONSTITUTION: This system is provided with an input/output device such as card reader 16 and a data processing unit consisting of main memory 1 including CPU, and in case of the data read from reader 16 or the data write to reader 16, data is stored in buffer memory 12 temporarily. Here, memory management routine 6 is provided; and in case that the reservation of buffer memories 12-1 and 12-2 is requested to routine 6 by the input/output management system, the processing is performed in the alternate buffer system when both memories 12-1 and 12-2 can be reserved, and transfer is executed with memory 12-1 when only one memory can be reserved. As a result, the corresponding processing operation can be performed even in case of the mixture of use request for buffer memories
