PURPOSE:To reduce the hardware quantity of an information processor by providing both a main memory sweep-out function and a buffer memory sweep-out function to one store buffer. CONSTITUTION:A store request is outputted from an arithmetic processor 1, and a store address is stored to a store register 8 via a selector 10. At the same time, the store data is stored to a store register 7. An address array 5 is indexed by the output of the register 8. A comparator 14 checks whether or not the corresponding block exists at a data array 6. The information on this check is stored in an entry of a display buffer for buffer memory sweep-out which is designated by a writing pointer. At the same time, the store address and the store data are stored to the entries of a store address buffer and a store data buffer from registers 8 and 7. |
