Zusammenfassung:System and method for prefetching pointer-referenced data. A method embodiment includes: tracking a plurality of load instructions which includes a first load instruction to access a first data that identifies a first memory location; detecting a second load instruction which accesses a second memory location for a second data, the second memory location matching the first memory location identified by the first data; responsive to the detecting, updating a list of pointer load instructions to include information identifying the first load instruction as a pointer load instruction; prefetching a third data for a third load instruction prior to executing the third load instruction; identifying the third load instruction as a pointer load instruction based on information from the list of pointer load instructions and responsively prefetching a fourth data from a fourth memory location, wherein the fourth memory location is identified by the third data.
