Memory binding for performance optimization of control-flow intensive behaviors
Kamal S. Khouri, Ganesh Lakshminarayana, Niraj Kumar Jha · 1999
This paper presents a memory binding algorithm for behaviors that are characterized by the presence of conditionals and deeply-nested loops that access memory extensively through arrays. Unlike previous works, this algorithm examines the effects of branch probabilities and allocation constraints. First, we demonstrate, through examples, the importance of incorporating branch probabilities and allocation constraint information when searching for a performance-efficient memory binding. We also show the interdependence of these two factors and how varying one without considering the other may greatly affect the performance of the behavior. Second, we introduce a memory binding algorithm that has the ability to examine numerous bindings by employing an efficient performance estimation procedure. The estimation procedure exploits locality of execution, which is an inherent characteristic of target behaviors. This enables the performance estimation technique to look at the global impact of t...
