ACCESS SYSTEM OF CACHE PRECEDING - NIPPON TELEGRAPH & TELEPHONE

Title:

ACCESS SYSTEM OF CACHE PRECEDING

Document Type and Number:

Japanese Patent JPS6031664

Kind Code:

A

Abstract:

PURPOSE: To prevent the deterioration of a system by limiting a block to be fixed on a cache to an area specified by an address in accessing and the address of preceding access.

CONSTITUTION: Sequential access already accessed the copy of a block A in a main storage buffer 30, i.e. a block (a) in the cache 2 and is accessing the copy of a block B, i.e. a block (b). The copy of a block C is stored in the cache 2 as a block (c) by block transfer from a main storage 3 to the cache 2 on the basis of the preceding access. Under said state, a fixed flag obtains "0" because sequential access passed the whole area of the block (a) indicating the fixing is released to be an object to be replaced.
