Abstract

PURPOSE: To increase the buffer hit rate by always residing the data at lower addres sections on the buffer memory.
CONSTITUTION: In transferring and storing the data on the main memory on the buffer memory unit in one block unit, the IR information is produced based on the address information of the data block, and the information produced is written in the address information storage areas 3'-0 to 3'-3 at the tag section 1' with the address information at the data block. Further, in data readout processing, when desired data is not in existence on the buffer memory unit, the IR information is referenced. The data block in which the IR information is Science (1), for example, is excluded from the block of the objective of replacement, i.e., replacement objective block so that the data block can be resident on the buffer memory unit. Thus, the buffer hit rate can be increased.
