Pointer Data Prefetching Method Based on CMP
Song Bao-wei · Jisuanji gongcheng · 2011
This paper proposes a pointer data prefetching method for the memory wall problem——pure traversal push mechanism.It utilizes multi-threading technology based on CMP,and dispatches a helper thread when the program runs which prefetches the demanded data into the shared cache in advance to hide the long memory access latency.Experimental results show that the pure traversal push mechanism improves the performance of pointer-chasing and memory intensive applications apparently.
