A Phased Prefetching Scheme for Irregular Data References
Ya Huang · Journal of Henan University · 2015
When dealing with the structurally complex irregular data applications,the effectiveness of conventional data prefetching techniques reduces.To solve this problem,a new phased prefetching technique for irregular data is presented based on memory access stream.Phased prefetching mechanism recognizes data access phases and prefetching phases by profiling programs at runtime,and adjusts prefetch operations accordingly.Experimental results show that phased prefetching mechanism can decrease useless prefetches and improve system performance of irregular data applications more effectively compared with conventional data prefetching techniques.
