Abstract
An information processing unit includes at least one cache memory provided between an instruction execution section and a storage section and a control section controlling content of address information based on a result of comparison processing between an address requested by a hardware prefetch request issuing section for memory access and address information held in an address information holding section, wherein when the control section causes the address information holding section to hold address information or address information in the address information holding section is updated, overwrite processing on the address information is inhibited for a predetermined time.
