Abstract

PURPOSE: To enable the introduction of disc cash, by the constitution that the data transfer can be made between the disc cash and the main memory and between the disc cash and the input and output channel.
CONSTITUTION: In case the disc cash is used, an input and output processor 12 receives the disc readout instruction from an operation processor 11 to check the presence of the record requested. If present, the record is transferred to the location designated by the main memory unit 14 to complete a series of operation. If absent, the record requested from the disc unit is read out to store it to the disc each memory section 3. If no vacant area is present, the record of the memory section 3 having the lowest priority is expelled for the storage. Next, the record is transferred to the designated memory unit of the main memory unit 14 from the memory section 3 to complete the operation of a series.
