The recent advances of hardware-based accelerators for machine learning—in particular neural networks—attracted the attention of embedded-systems designers and engineers. Since embedded systems usually operate with strict resource constraints, knowledge about the resource demand (ie, time and power) for executing machine-learning workloads is key. This paper presents Precious, an approach, as well as a practical implementation, of a system that estimates execution time and power draw of convolutional and fully-connected neural networks that execute on a commerciallyavailable off-the-shelf embedded accelerator hardware for neural networks (ie, Google Coral Edge TPU).
