A Context-Aware Library for Mathematical Approximations

Abstract

We have built a mathematical library that includes a series of functions with different implementations with varying precision. We couple this library with a system service that monitors the computer context, including energy consumption, and according to this context, using specified rules, dynamically changes the implementations used by the target applications. Our case studies show that our library can trade-off at most of 4% degradation in application quality up to 40% savings in energy consumption.
