Include the DSP (Digital Signal Processing) subsystem as a part of the
Zephyr build. This enables applications to include and call into the
<zephyr/dsp/dsp.h> header.

help
Implement the various zephyr DSP functions using the CMSIS-DSP library. This feature
requires the CMSIS module to be selected.
config DSP_BACKEND_CUSTOM
bool "Do not use any Zephyr backends for DSP"
help
Rely on the application to provide a custom DSP backend. The implementation should be
added to the 'zdsp' build target by the application or one of its modules.
