Download the latest firmware version from Downloads.

Sample Vision and Sensing Application(Previously called AI Post Processing Layer (PPL))

The most important updates are:

  • AI Post Processing Layer (PPL) is now called Vision and Sensing Application.
  • Analysis of the inference data and transmission of the analysis results are more flexible.

The new Vision and Sensing Application is described in the important notice Discontinuation of Base AI models and changes in Vision and Sensing Application data processing methods.

Download the latest sample applications from Downloads.

Note: To use the new Vision and Sensing Application, the edge AI device SZP123S-001 firmware must be updated to the latest version.

Console

The main updates are:

  • Added a feature to remove an AI model from an edge AI device. Previously, it was only possible to replace AI models. Note: The edge AI device SZP123S-001 firmware must be updated to the latest version.
  • AI model converter enhancements
    • Added support for new layers:
      • sqrt
      • Rsqrt
      • Abs
      • gather
      • top_k
      • Unstack
    • Updated tflite Conv2DTranspose layer requirements.
  • Discontinued Base AI Model. For more information, see the important notice Discontinuation of Base AI models and changes in Vision and Sensing Application data processing methods.
    The types of model Console can handle are:
    • Custom Vision Object Detection via Create menu.
    • tflite import via Create menu.
    • Purchase Neurala Brain Builder for AITRIOS (On-Premises) via Portal Marketplace and train/generate classification tflite models that can be imported to Console.
