The apps tree is apps/mlearning, but documentation lived under the misspelled mlearing path as title-only stubs. TensorFlow Lite Micro and standalone CMSIS-NN had no pages. Rename the directory to mlearning, document each package from the current Kconfig and build files, and add the sim:tflm board configuration.

``cmsis`` CMSIS Libraries
|
|
=========================
|
|
|
|
``apps/mlearning/cmsis`` fetches `CMSIS 5
|
|
<https://github.com/ARM-software/CMSIS_5>`_ and builds CMSIS-DSP and
|
|
CMSIS-NN from that tree. Default version is ``5.8.0``
|
|
(``CONFIG_CMSIS_VER``).
|
|
|
|
This package is aimed at NNABLA and generic DSP use. For TensorFlow Lite
|
|
Micro kernel acceleration, use :doc:`../cmsis-nn/index` instead.
|
|
|
|
Enable ``CONFIG_CMSIS`` from :menuselection:`Application Configuration -->
|
|
Machine Learning Support --> CMSIS Libraries`.
|
|
|
|
``CONFIG_CMSIS_DSP``
|
|
CMSIS-DSP. Optional ``CONFIG_CMSIS_DSP_ARM_MATH_MATRIX_CHECK`` and
|
|
``CONFIG_CMSIS_DSP_ARM_MATH_ROUNDING`` map to ``ARM_MATH_MATRIX_CHECK``
|
|
and ``ARM_MATH_ROUNDING``. ``CONFIG_ARCH_FPU`` defines
|
|
``__FPU_PRESENT``.
|
|
|
|
``CONFIG_CMSIS_NN``
|
|
CMSIS-NN from the CMSIS 5 tree. Depends on ``CONFIG_CMSIS_DSP``. A
|
|
NuttX patch (``cmsis-nn-support_nnabla.patch``) adds CHW convolution
|
|
helpers used by NNABLA.
|
|
|
|
Public headers are added from:
|
|
|
|
- ``CMSIS_5/CMSIS/Core/Include``
|
|
- ``CMSIS_5/CMSIS/DSP/Include`` (when DSP is enabled)
|
|
- ``CMSIS_5/CMSIS/NN/Include`` (when NN is enabled)
|
|
|
