Memory Hierarchy Optimization Based on Empirical Search
Zhenghua Wang · Computer Engineering and Applications Journal · 2006
Memory wall is an important factor that effects program performance optimization.And its alleviation relies on memory optimization of the program.We propose the approach of Memory Hierarchy Optimization based on Empirical Search.It turns the problem of optimizing across multiple levels of the memory hierarchy to an empirical search to optimization parameter problem,and selects the best overall solution.Experiments show that this approach can greatly decrease time on memory access and memory access factor to performance,therefore,effectively alleviate the problem of memory wall,moreover,it can automatically adapt different programs.
