Abstract

Portable systems today are designed with lowering the energy consumption as the primary design metric. This is unfortunate, since maximizing battery lifetime is a more appropriate metric, and lowering energy does not necessarily mean improving battery lifetime. We first show how to design battery-friendly implementations of common signal processing kernels such as FIR filters and FFT. The basic idea is to generate a load profile that results in better battery behavior. Next, we demonstrate how frequency scaling can be used effectively to improve the battery behavior of an application such as MPEG2.
