Hello

We Have Product Designed With S32K11x In Production For One Year But We Still Not Really Familiar With Full Features Of S32K Family. Especially DSP  That Is Built In The S32K148. Does That DSP With Serial Audio Interface Intend For Audio Use Case? For Example Audio Codec Target Application? Where Is The SDK For This Mentioned DSP?

Hi,

DSP extension is a feature of Cortex M4 core for general use, it’s not special feature of S32K14x.

For more details, see:

https://developer.arm.com/architectures/instruction-sets/dsp-extensions/dsp-for-cortex-m

There’s also a link to free CMSIS-DSP library. It’s not included in S32 Design Studio.

There’s our own library AMMCLIB included in S32DS.
