Part of the gap can even be eliminated with sophisticated programmer- and compiler-directed software-prefetching mechanisms [2, 4, 30, 41].

Webb31 dec. 2016 · CPU Hardware Prefetch is a BIOS feature specific to processors based on the Intel NetBurst microarchitecture (e.g. Intel Pentium 4 and Intel Pentium 4 Xeon). These processors have a hardware prefetcher that automatically analyzes the processor’s requirements and prefetches data and instructions from the memory into the Level 2 … WebbPrefetching, i.e., exploiting the overlap of processor com-putations with data accesses, is one of several approaches for tolerating memory latencies. Prefetching can be ei-ther hardware-based or software-directed or a combination of both. Hardware-based prefetching, requiring some sup-port unit connected to the cache, can dynamically han-
