Automated energy/performance macromodeling of embedded software

Efficient energy and performance estimation of embedded software is a critical part of any system-level design flow. Macromodeling based estimation is an attempt to speed up estimation by exploiting reuse that is inherent in the design process. Macromodeling involves pre-characterizing reusable software components to construct high-level models, which express the execution time or energy consumption of a sub-program as a function of suitable parameters. During simulation, macromodels can be used instead of detailed hardware models, resulting in orders of magnitude simulation speedup. However, in order to realize this potential, significant challenges need to be overcome in both the generation and use of macromodels-- including how to identify the parameters to be used in the macromodel, how to define the template function to which the macromodel is fitted, etc. This paper presents an automatic methodology to perform characterization-based high-level software macromodeling, which addre...
