Power and Thermal Characteristics of a Pentium M System

چکیده
In this work, we characterize the power and thermal characteristics of a Pentium M system in response to a widely available power-management mechanism, DVFS (dynamic voltage and frequency scaling) and cooling capacity. We observe transient and steady-state responses to changing the DVFS state with custom microbenchmarks and develop a model that captures the power-thermal relationship for this system. We also record the power and thermal response to the SPEC CPU2000 benchmark suite executing at 2 GHz to determine the effects of a realistic workload with fluctuating power consumption. The measured data from live hardware illustrate the complex interaction between CPU and ambient temperatures and provides insight for power and temperature management by identifying the magnitude and timescale of power and thermal responses to control settings.
