Integrate Google's upstream TFLite Micro microfrontend library (under Apache-2.0 with patent grant protection) to support PCAN (Per-Channel Automatic Gain Control Normalization) in SOF: - west.yml: add tensorflow remote and tflite-micro project definition - src/math/pcan: compile Google's upstream pcan_gain_control.c/util.c and noise_reduction.c/util.c directly into SOF math library - src/include/sof/math/pcan.h: expose PCAN math API and wrapper helpers - src/audio/mfcc: integrate PCAN into MFCC audio processing pipeline - src/audio/mfcc/tune/setup_mfcc.m: add PCAN configuration preset - test/cmocka/src/math/pcan: 5-phase CMocka test suite validating LUT generation, WideDynamicFunction, PcanShrink, streaming IIR estimation, and numerical corner cases against Octave reference models - src/math/pcan/pcan_hifi4.c: add HiFi DSP SIMD optimizations Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
…ure documentation Document: - Dependencies: West manifest, tflite-micro upstream repo, CMake, GNU Octave, CMocka, DSP toolchains - Build instructions for host CMocka unit tests and Zephyr target firmware - Topology configuration generation via Octave setup_mfcc.m - Mathematical formulation and pipeline data flow for MFCC and PCAN Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com>
