==Introduction==
This Technical Note (TN for short) belongs to the series introduced [[ML-TN-001_-_AI_at_the_edge:_comparison_of_different_embedded_platforms_-_Part_1|here]].
Specifically, it illustrates the execution of [[ML-TN-001_-_AI_at_the_edge:_comparison_of_different_embedded_platforms_-_Part_1#Reference_application_.231:_fruit_classifier|this inference application (fruit classifier)]] when executed on the [[:Category:Mito8M|Mito8M SoM]], a system-on-module based on the NXP [https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-8-processors/i-mx-8m-family-armcortex-a53-cortex-m4-audio-voice-video:i.MX8M i.MX8M SoC].

The following images show the graphs of the models after conversion (click to enlarge):

|Four threads are created beside the main process (supposedly, this quantity is set accordingly to the number of physical cores available). Nevertheless, they seem to be constantly in sleep state.

The same tests were repeated using a network file system (NFS) over an Ethernet connection, too. No significant variations in the prediction times were observed.
In conclusion, to maximize the performance in terms of execution time, the model has to be fully-quantized and the number of threads has to be specified explicitly.
