Abstract
Array of pointers prefetching is described. In accordance with described techniques, a pointer target instruction is detected by identifying that a destination location of a load instruction is used in an address compute for a memory operation and the load instruction is included in a sequence of load instructions having addresses separated by a step size. An instruction for fetching data of a future load instruction is injected in an instruction stream of a processor. The data of the future load instruction is stored in a temporary register. An additional instruction is injected in the instruction stream for prefetching a pointer target based on an address of the memory operation and the data of the future load instruction.
