This directory acts as the bridge for running ML models.

Integrates TensorFlow Lite for Microcontrollers into the SOF audio pipeline. Evaluates pre-trained neural network topologies inline with the audio stream for tasks like wake-word, noise cancellation, or sound classification.

• Kconfig: Enforces requirements for C++17 support and core framework staging logic (COMP_TENSORFLOW).
• CMakeLists.txt: An intricate build specification linking the Tensilica neural network library block computations (nn_hifi_lib) and the TensorFlow Lite micro core engine (tflm_lib). Also hooks the tflm-classify.c SOF adapter via compiler flags explicitly enforcing memory, precision, and XTENSA optimizations.
• tflmcly.toml: Topology definition for the specific TFLM Classifier implementation binding the engine against the UUID UUIDREG_STR_TFLMCLY.
