A New Hardware Prefetch Method and Its Effect on System Performance
Deng Rang · Computer Engineering and Science · 2001
The large latency of memory access is a key obstacle to achieving high processor utilization.Prefetch is one way to hide memory access latency,it is normally performed by explicitly executing instructions to move data close to the processor before they are actually needed,but this kind of prefetch will add burden on the programmers.In this paper,a new technology,which is realized by a VPFB in memory controller design,is presented,and its efficiency is analyzed by simulation.
