Abstract

PURPOSE: To enhance the performance by providing a number of data blocks which are not used in the active mode of the processor under execution onto the memory as the objects of replacement in cace no desired data exists in the buffer memory.
CONSTITUTION: Replacement array 6 which generates the replacement information within each entry position is provided in correspondence to each entry position of the buffer memory containing plural entry positions. In this control memory containing plural entry positions. In this control system, data parts 1-1W1-4 containing plural data entries, tag entry parts 2-1W2-4, and replacement circuit 7' including mode decision part 10 and replacement decision part 11 are provided respectively. In addition, mode bits 9-1W9-4 are installed to tag parts 2-1W2-4, and the contents of address register 3 to which the external information is set is compared with the contents read out from parts 2-1W 2-4 through comparators 4-1W4-4. Then the data which is not used in the active mode of the processor under execution is supplied to circuit 7' as the subject of replacement
