.. _tflm_ethosu: Arm(R) Ethos(TM)-U Tensorflow Lite for Microcontrollers test application ######################################################################## A sample application that demonstrates how to run an inference using the TFLM framework and the Arm Ethos-U NPU. The sample application runs a model that has been downloaded from the `Arm model zoo `_. This model has then been optimized using the `Vela compiler `_. Vela takes a tflite file as input and produces another tflite file as output, where the operators supported by Ethos-U have been replaced by an Ethos-U custom operator. In an ideal case the complete network would be replaced by a single Ethos-U custom operator. Building and running ******************** This application can be built and run on any Arm Ethos-U capable platform, for example Corstone(TM)-300. A reference implementation of Corstone-300 can be downloaded either as a FPGA bitfile for the `MPS3 FPGA prototyping board `_, or as a `Fixed Virtual Platform `_ that can be emulated on a host machine. Assuming that the Corstone-300 FVP has been downloaded, installed and added to the ``PATH`` variable, then building and testing can be done with following commands. .. code-block:: bash $ west build -b mps3_an547 zephyr/samples/modules/tflite-micro/tflm_ethosu $ FVP_Corstone_SSE-300_Ethos-U55 build/zephyr/zephyr.elf
