Prefetch degree and prefetch distance of a single hardware …
WebLosses can also be reduced by tuning the prefetching degree or distance. Sequential prefetching with adaptive degree was first proposed in Dhalgren et al. [10], on multiprocessors, focusing on prefetching usefulness. Adaptive stream prefetching is explored in Srinath et al. [11], balancing usefulness, timeliness and pollution. WebThe prefetch distance and prefetch position are important factors that affect the prefetch effect. If an accurate judgment cannot be given at compile time, some prefetch operations that do not benefit will occur. In addition, pre-fetch instructions lack accurate cost-benefit evaluation before WebPrefetching is a central element in most microarchitectures. Many different algorithms have been proposed with varying degrees of complexity and effectiveness. There is a tradeoff among various aspects of coverage, accuracy, ... we can control prefetch distance. Specifically, the appropriate prefetch distance is d = AMAT+m Titer jb blade\u0027s
