Stride and Pointer Based Prefetching in Chip Multiprocessor
Longbing Zhang · Jisuanji gongcheng · 2009
Based on the analysis of benchmark program’s memory access behavior,this paper proposes stride and pointer based prefetching scheme which can capture regular data access pattern and pointer access pattern,and implements a prefetcher between L2 cache and memory using a global history buffer.Full system simulation shows that this prefetching scheme can improve the commercial benchmark’s performance by 14%,and improve the scientific benchmark’s performance by 34.5%.
