PURPOSE:To speed up accessing, by providing a comparison circuit which collates a part of content and a part of address information, when the address information performing replacement processing of a part of content comes, while actual write is executed after checking. CONSTITUTION:In reading out the content of a high speed buffer storage device and processing write, when an execution address is set to a register 1, the content of a tag section 2 is read out and when the corresponding address exists, a block number is set to a block number register 5 for actual write processing. When the replacement processing is inserted during this time, the execution address and write address information are compared with a line address comparison circuit 7. When the comparison circuit generates a coincident output, the write processing is done after checking is again performed. Thus, the delay of processing can be avoided. |
