S32k144 uses DSP module

zhangchun — Wed, 25 Oct 2023 08:16:12 GMT

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.php
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.
