Analysis and Optimization Strategy of Big Memory Access Performance Based on the XScale Architecture
Yao Guo-liang · Dianzi qijian · 2008
The paper investigates how the system design and its software implemention effect the big memory access performance based on the Intel Xscale architecture.Through expriment and analysis in memory access implemented by DMA and CPU core,some general optimization strategy is presented.A preferable experimental result in the YUV to RGB transversion is achieved based on this strategy.
