  title = {Energy and Performance Optimization of a Simple Video Encoder on the Jetson--TK1},
  abstract = {This poster analyses the energy consumption of a simple video encoder running on NVIDIA\&$\#$39;s Tegra K1 processor. The total energy consumption of the video encoder is investigated under the influence of different hardware configurations, such as which processors (CPU clusters or GPU) are used, DVFS algorithms, and whether performance optimisations like NEON are implemented. We find that NEON instructions and multithreading generally have positive effects on energy consumption, saving between 25 to 40 \% energy compared to a non\­optimised, naive implementation. GPU offloading is found to be marginally better than CPU execution by an amount of 1.7 \%.},
