Abstract
In this paper we introduce a novel approach for measuring
and estimating effect of performance scaling for user
interface latency and power consumption. Growing demand
for higher performance in battery powered devices such
laptop PC's has spawned techniques for dynamically
decreasing performance in order to save energy and yet
preserve high peak performance. For the evaluation of
this approach we analyse system that uses dynamic voltage
and frequency scaling technology for reducing power
consumption based on CPU load. We focus on analysing
effect of different parameters of the dynamic performance
scaling such as length of time between load predictions.
By using this measurement approach we were able to
distinguish clear differences in energy consumption as
well as in user interface performance.
