Webb1 mars 1999 · A prefetching architecture using such a mechanism is defined and evaluated with respect to its accuracy, the impact of the instruction prefetching on performance, and its interaction with sequential prefetching. Both PC-based and history-based predictors are used to perform a single-lookup prediction. Webb31 okt. 2024 · Instruction prefetching is a latency hiding method that allows the LLC to send instructions to the L1-I cache. In order to design a high-performance cache architecture, prefetching instructions in the L1-I cache is a fundamental approach.
