The NuMicro® Cortex-M4 series BSP (Board Support Package) includes the Cortex®-M4 DSP library which is comprehensive and easy to use and develop directly. Besides, the calculation algorithms in the library have been optimized to effectively reduce the operation time.

To enable DSP with Keil:

After starting Keil, select Target Options, go to the C/C++ tab page, and enter “ARM_MATH_CM4=1” in the Define field.
Add “arm_cortexM4lf_math.lib” to the Library (\Library\CMSIS\Lib\ARM).
Include the arm_math.h file to the main.c. After that, user can call the DSP library in the main.c.

To enable DSP with IAR:

After starting IAR, select Options, go to the General Options page, and enable the Use CMSIS and DSP library under the Library Configuration page.
Add “arm_cortexM4lf_math.lib” to the Library (\Library\CMSIS\Lib\ARM).
Include the arm_math.h file to the main.c. After that, user can call the DSP library in the main.c.

Note: arm_cortexM4lf_math.lib includes the Cortex®-M4 DSP library.
