Abstract: The complexity of mobile devices is continuously growing due to the
increasing requirements on performance. In portable systems such as smart
cards, not only performance is an important attribute, but also the power and
energy consumed by a given application. It is mandatory to accomplish software
power optimizations based on accurate power consumption models characterized
for the processor. Both the optimization and the characterization are carried
out mostly manually and are thus very time consuming processes. This paper
presents an environment for automated instruction set characterization, based
on physical power measurements. Further, an optimization system is presented
that allows an automated reduction of power peaks based on a compiler
optimization.
Keywords: Power characterization, software power optimization, peak reduction, iterative compiling, smart card systems, power profile analysis
