Abstract
The present application describes some embodiments of a prefetcher that tracks multiple stride sequences for prefetching. Some embodiments of the prefetcher implement a method including generating a sum-of-strides for each of a plurality of stride lengths that are larger than one by summing a number of previous strides that is equal to the stride length. Some embodiments of the method also include prefetching data in response to repetition of one or more of the sum-of-strides for one or more of the plurality of stride lengths.
