S32k144 uses DSP module

[zhangchun]

Hello, currently I need to use the S32k144 DSP module in my project.

May I ask how to operate S32k144 to use DSP instructions? Can the DSP module improve its performance for simple addition, subtraction, multiplication, and division operations?

Finally, how should I check and confirm that the DSP module has been used in the current project

Hi @zhangchun 
you can use either CMSIS library:
https://www.arm.com/products/processors/cortex-m/cortex-microcontroller-software-interface-standard....
It is not included in S32 Design Studio.
Or you can use AMMCLIB which is included in S32 Design Studio. AMMCLIB has many DSP functions and have better performance than CMSIS.
