But these frameworks cannot be converted to each other. ONNX acts as a bridge between them. One framework can convert its model to ONNX and then convert ONNX model to the other framework model. text/html 2024-03-12T05:26:36+00:00 Anonymous (anonymous@undisclosed.example.com) Application Source Code https://docs.khadas.com/products/sbc/vim3/npu/npu-app?rev=1710235596&do=diff vim3 vim3l amlogic npu opencv Application Source Code Guide to compiling the NPU application on the VIM3/3L.

We can make use of the available computation power for running TFLite models directly using TIM-VX Libraries by leveraging TFLite interpreter Delegate. The Delegate is provided by VeriSilicon as VeriSilicon/tflite-vx-delegate and the provided examples are made to make use of it.
