ABSTRACT:
A processor equipped with a pre-fetch function comprises: first layer cache memory having a first line size; second layer cache memory that is on the under layer of the first layer cache memory and that has a second line size different from the first line size; and a pre-fetch control unit for issuing a pre-fetch request from the first layer cache memory to the second layer cache memory so as to pre-fetch a block equivalent to the first line size for each second line size.
