Abstract

This paper proposes an approach for efficiently deploying neural network (NN) models on highly resource-constrained microcontroller architectures, particularly AURIX TC3xx microcontrollers. Here, compression and optimization techniques of the NN model are required to reduce execution time while maintaining accuracy on the target microcontroller. Furthermore, especially on AURIX TriCores that are frequently used in the automotive domain, there is a lack of support for automatic conversion and deployment of pretrained NN models. In this work, we present an approach that fills this gap, enabling the conversion and deployment of so-called thermal neural networks on AURIX TC3xx microcontrollers for the first time. Experimental results on three different NN types show that, when pruning of convolutional neural networks is applied, we can achieve a speedup of 2.7× compared to state-of-the-art thermal neural networks.
