FORAY-GEN: Automatic Generation of Affine Functions for Memory Optimizations
In today’s embedded applications a significant portion of energy is spent in the memory subsystem. Several approaches have been proposed to minimize this energy, including the use of scratch pad memories, with many based on static analysis of a program. However, often it is not possible to perform static analysis and optimization of a program’s memory access behavior unless the program is specifically written for this purpose. In this paper we introduce the FORAY model of a program that permits aggressive analysis of the application’s memory behavior that further enables such optimizations since it consists of ‘for’ loops and array accesses which are easily analyzable. We present FORAY-GEN: an automated profilebased approach for extraction of the FORAY model from the original program. We also demonstrate how FORAY-GEN enhances applicability of other memory subsystem optimization approaches, resulting in an average of two times increase in the number of memory references that...
