A method and hardware apparatus for data prefetching. In one embodiment, the method of the present invention comprises first calculating a local stride value by computing the value between two address references of a first load instruction. The local stride value of the first load instruction is used as a global stride value for address prefetching for a second load instruction, where the second load instruction is different from the first load instruction. An appropriate global stride value is added to a previous address value associated with a previous occurrence of the second load instruction, producing an address location for prefetching a block of data.
