Mathematical Analysis of Statistical Sampling for Estimating Computer Cache Performance

Abstract

Computer cache memory simulations consume a lot of resources, both in terms of disk space and CPU time. A statistical approach to this problem is proposed in which program traces are sampled at certain intervals, significantly reducing the required computer resources. Using, both the mathematical analysis and experimentation, we show that this approach can achieve a high accuracy in predicting the hit and miss ratios for cache simulations.
