Uncovering Detailed Power Characterizations of GPUs on Edge Platforms

GPUs in edge platforms operate on a tight energy budget.Although power characterization of server GPUs has been studied, there has been a lack of systematic study of the power and thermal characteristics of edge GPUs.In this paper, we provide a detailed characterization of the power, energy, and temperature of edge GPUs by designing micro-kernels for instruction-level power analysis and executing a real-world application for application-level power characterization.From the observations, we discuss the limitations of existing power simulators and also suggest power optimization methods.
