Some questions about X-Cube-Ai

[PYL4869]

Hi

Regarding X-Cube-Ai, it seems to be closed source, I wonder if its underlying implementation relies on the api provided in CMSIS-NN? Or did ST implement it all by itself ?

Hi,

The implementation of the kernels is partially based on the CMSIS-NN, there is a mix to address efficiently (in term of performance and memory peak usage) the different STM32 series in relation to the targeted ARM toolchains. Usage of the CMS-NN is regularly evaluated and can be used case-by-case to address the new Cortex-m architecture or/and to upgrade legacy kernel implementations.
