Abstract
PURPOSE: To update replacement information by a simple method of increasing the information in an entry position, by providing circuits which determine the entry position for replacement and update the content of a replace information holding part.
CONSTITUTION: The content of the main memory unit is transferred, block by block, onto the buffer memory with several entry positions and at the time of the execution of a process attaining access to this memory, effective bits are provided corresponding to block units transferred to respective entry positions on the buffer and corresponding to entry positions, replacement array 1 is also provided which holds replacement information on the mutual unit of information at each entry position. Further, replacement entry circuit 5 which determines the entry position for replacement on the basis of the content of array 1 and replacement information update processing part 7 which updates the content of array via write register 9 according to the content of array 1 are both provided, and the information is updated with the entry position of the replacement information made higher.
