The quantization type of all operators is symmetric quantization. Now ESP-DL supports both 8-bit and 16-bit. The rounding for ESP32-S3 is rounding half up. The rounding for ESP32-P4 is rounding half to even.
The ESP-DL operator interface is aligned with ONNX. The opset 13 is recommended to export ONNX. Currently, the following 32 operators have been implemented and tested. Some operators do not implement all functionalities and attributes. Please refer to the description of each operator or test cases for details.
