TDA4AL-Q1: Inquiry Regarding Resource Utilization Measurement for C7x and C7+MMA Accelerator on TDA4AL with QNX

Part Number: TDA4AL-Q1

Tool/software:

Dear TI Support Team,

I am currently working with the TDA4AL chip running QNX OS, and I need to measure the resource utilization of the C7x and C7+MMA deep learning accelerator, checking this NPU's 8 TOPs are enough or not.

We are already using perf analyzer, monitoring only CPU(A72) resources. Given this setup, I would like to confirm the following:

  1. Are there any specific libraries or binaries that must be installed to accurately measure the resource usage of the C7+MMA accelerator?
  2. Is it possible to obtain resource utilization data via sysfs or procfs interfaces on QNX for the TDA4AL platform? If so, could you please provide the relevant file paths or usage instructions?
  3. Alternatively, are there APIs or sample codes available within the TI SDK that allow for direct measurement of C7+MMA usage? If so, I would appreciate detailed guidance or references to documentation.

I would be grateful if you could confirm whether the approaches I described above are correct, and advise on the recommended method for resource monitoring in this environment.

Thank you for your support.

Best regards,

    If you're using Vision Apps, the framework includes APIs that expose performance statistics. Please refer to the following documentation: Performance statistics reporting APIs

    Additionally, you may find memory usage-related APIs here: Memory APIs

    For sample code and usage reference, please refer to: <PSDK>\vision_apps\apps\utilities

    You can check the vision_apps\apps\utilities\app_load_test directory.

    For documentation, please check: Utility Applications & Tests
