Abstract
An apparatus includes memory circuitry including a first data structure and prefetch circuitry that is coupled to the memory circuitry. The prefetch circuitry is to store, in the first data structure, a first subregion entry corresponding to a first subregion of a memory region allocated to a program. The first subregion entry is to include a plurality of delta values. A first delta value of the plurality of delta values represents a first distance between two cache lines associated with consecutive memory accesses within a second subregion of the memory region. The prefetch circuitry is further to detect a first memory access of a first cache line in the first subregion, identify prefetch candidates based on the first cache line and the plurality of delta values, and issue at least one prefetch request based on at least two of the prefetch candidates to be prefetched into a cache.
