Sample Zephyr Tracing Report

This section contains a sample performance report with Zephyr tracing section, generated by Kenning using Zephelin.

The CI is set up as follows:

  • Environment: Github Actions

  • Task: Anomaly Detection on CATS dataset

  • Tracing tool: Zephelin

  • Compiler framework: TFLite

  • Platform: stm32f746g_disco board
