ADAPTIVE DATA PREFETCHING

A system and method for adaptive data prefetching in a processor enables adaptive modification of parameters associated with a prefetch operation. A stride pattern in successive addresses of a memory operation may be detected, including determining a stride length (L). Prefetching of memory operations may be based on a prefetch address determined from a base memory address, the stride length L, and a prefetch distance (D). A number of prefetch misses may be counted at a miss prefetch count (C). Based on the value of the miss prefetch count C, the prefetch distance D may be modified. As a result of adaptive modification of the prefetch distance D, an improved rate of cache hits may be realized.
