Detailed Description

lbuild module: modm:cmsis:dsp

This module provides the CMSIS-DSP library. Please see the API documentation for details.

Note:

• The library should be accessed through the arm_math.h and arm_math_f16.h headers, as these include necessary configuration options.
• This module splits up the library into submodules to speed up compilation by only including the math functions you really need.
• You can enable 16-bit floating point support via the option with_f16.

Configuration

You can define your own configuration in the <arm_math_local.h> file which will automatically be included at the beginning of the arm_math.h and arm_math_f16.h files. This way changes to your CMSIS-DSP configuration will only affect its source files and not recompile your whole project.

Example <arm_math_local.h> configuration:

Module Options

modm:cmsis:dsp:with_f16: Include f16 format functions

16-bit floating point is only used for storage, since the Cortex-M FPU does not support the format in hardware.
