Industries,Microarchitecture,Prefetching,Hardware,Software,Performance analysis,HistoryInstruction prefetching can play a pivotal role in improving the performance of workloads with large instruction footprints and frequent, costly frontend stalls. In particular, Fetch Directed Prefetching (FDP) is an effective ...
Finally, we model the use of idle instruction cache ports to filter prefetch requests, thereby saving bus bandwidth to the L2 cache 展开 关键词: instruction sets parallel architectures performance evaluation L2 cache fetch directed instruction prefetching instruction cache misses instruction cache ports ...

This allows the branch predictor to run far in advance of the address currently being fetched by the instruction cache. The decoupling enables a number of architectural optimizations including multi-level branch predictor design and fetch directed instruction prefetching.; A multi-level branch predictor...
