A Machine Learning Methodology for Cache Memory Design Based on Dynamic Instructions

Cache memories are an essential component of modern processors and consume a large percentage of their power consumption. Its efficacy depends heavily on the memory demands of the software. Thus, finding the optimal cache for a particular program is not a trivial task and usually involves exhaustive simulation. In this article, we propose a machine learning-based methodology that predicts the optimal cache reconfiguration for any given application, based on its dynamic instructions. Our evaluation shows that our methodology reaches 91.1% accuracy. Moreover, an additional experiment shows that only a small portion of the dynamic instructions (10%) suffices to reach 89.71% accuracy.
