Energy efficiency of multimedia processing is a hot topic in modern, mobile computing where the lifetime of battery-powered devices is low. Authors often use power models as tools to evaluate the energy-efficiency of multimedia workloads and processing schemes. A challenge with these models is that they are built without sufficiently deep hardware knowledge(More)
Energy consumption is an important concern for mobile devices, where the evolution in battery storage capacity has not followed the power usage requirements of modern hardware. However, innovative and flexible hardware platforms give developers better means of optimising the energy consumption of their software. For example, the Tegra K1 System-on-Chip(More)
Energy consumption is an important issue for mobile devices, as the technological development in battery technology has not kept pace with the power requirements of mobile hardware. In this paper, we use a video rotation filter to study the effects of CPU and GPU frequency scaling in terms of performance and energy. Our platform is the Tegra K1 mobile(More)
