+## Performance 
+
+There are many articles compared NNoM with other famous MCU AI tools, such as TensorFlow LiteSTM32Cube.AI .etc. 
+
+**Raphael Zingg etc** from Zurich University of Applied Sciences compare nnom with tflite, cube, and e-Ai in their paper  ["Artificial Intelligence on Microcontrollers"](https://github.com/InES-HPMM/Artificial_Intelligence_on_Microcontrollers/blob/master/Artificial_Intelligence_on_Microcontrollers.pdf) blog https://blog.zhaw.ch/high-performance/2020/05/14/artificial-intelligence-on-microcontrollers/

+
+Both articles shows that NNoM is not only comparable with other popular NN framework but with faster inference time and sometime less memory footprint.
