For a more detailed description of the build graph with all major components, see Building.
There are source files in the repository that form the core of the Machine Leaning flow for all the use cases. These are exposed as APIs that the examples can use and even be combined to form chained use cases. The API sources are designed to be portable across platforms and provide functionality for preprocessing of data, running an inference, and postprocessing of results. These allow a common flow for all use cases with minor differences in how each of these blocks are instantiated.
As an independent CMake project, these APIs can be used by or integrated into other projects easily. We also produce CMSIS Packs with these sources, so they could be used in all tools/IDEs (for example, Arm® Development Studio and Keil® µVision®) that support the use of CMSIS Packs.
To run an ML application on the Cortex-M and Ethos-U NPU, please, follow these steps:
NOTE: A Docker image built from the
Dockerfileprovided will have all the required packages installed.
To get familiar with these steps, you can follow the quick start guide.
Note: The default flow assumes Arm® Ethos™-U55 NPU usage, configured to use 128 Multiply-Accumulate units and is sharing SRAM with the Arm® Cortex®-M55.
Ml embedded evaluation kit supports:
Ethos™-U NPU Default MACs/cc Other MACs/cc supported Default Memory Mode Other Memory Modes supported Ethos™-U55 128 32, 64, 256 Shared_Sram Sram_Only Ethos™-U65 256 512 Dedicated_Sram Shared_Sram
