ABSTRACT:
A buffer storage system and method using a page designating address and an intra-page address for information processing according to a logical address is provided. The buffer storage system includes a page designating address for designating a page in a virtual address space, and an intra-page address for indicating an address in a given page. An address supply unit for outputting an address signal comprising a portion of the page designating address and the intra-page address may be included. The buffer storage system also provides a data storage unit for storing a portion of data from a main storage in a storage location corresponding to the portion of the page designating address and the intra-page address. The buffer storage system includes a plurality of address information storage units of a number determined by the portion of the page designating address. The address information storage units store address information concerning the storage location of the part of data in a storage location designated by an address of which only a portion of the page designating address is different. The buffer storage system may also include an invalidation unit for performing, in response to a write instruction to main storage, outputs of the address information storage units and a real address corresponding to the supplied logical address, a replacement of data in the data storage unit based on supplied write data and an invalidation of an address information corresponding to the data to be replaced. Replacement and invalidation may be simultaneously performed.
