A high-precision, hybrid GPU, CPU and RAM power model for generic multimedia workloads

Kristoffer Robin Stokke, +3 more
TL;DR: This work introduces a modelling methodology which can be used to build a generic, high-precision power model for the Tegra K1's GPU and memory, which achieves an average accuracy above 99 % over all operating frequencies, and has been rigorously tested on several multimedia workloads.
Journal ArticleDOI
