INTRODUCTION Hardware prefetching is an important feature of modern high-performance processors. When the application working set is too large to ﬁt in on-chip caches, disabling hardware prefetchers may result in severe performance loss.

WebbHardware Data stored in general reg-isters If the traversal decisions depend on some external value stored outside the data structure (e.g., a value being searched), this could provide a useful breakdown between traversal paths. Hardware Previously loaded data Data acquired in previous accesses (globally or within the same partial context) Hardware WebbGenerally, prefetching can be implemented in hardware or software. The software prefetching is normally implemented as an instruction in processors instruction (like fetch instruction). The purpose of this project is to discuss the hardware prefetching. Moreover, we present three different hardware prefetching techniques. clutch license plateWebbHardware prefetching.
