Hi Wei,

I'm aware of two DSP libraries:

- CMSIS DSP which is not included in S32 Design Studio but you can download official release from ARM web site and use the library in your project:

https://developer.arm.com/tools-and-software/embedded/cmsis

- AMMCLIB which is included in S32 Design Studio. AMMCLIB has many DSP functions and should have better performance than CMSIS  DSP.

Regards,

Lukas
