Abstract

Systems and methods that provide directional prefetching are provided. In one embodiment, a method may include one or more of the following: storing a first block and a second block in a prefetch buffer; associating a first block access with a backward prefetch scheme; associating a second block access with a forward prefetch scheme; and, if the first block is accessed before the second block, then performing a backward prefetch with respect to the first block.
