dsp_naturedsp

Overview

The dsp_naturedsp demo application a short self-test of selected NatureDSP functions.

This demo contains two applications:

  • cm33/ is the ARM application for Cortex-M33 core

  • dsp/ is the DSP application for HiFi4 core

The release configurations of the demo will combine both applications into one ARM image. With this, the ARM core will load and start the DSP application on startup. Pre-compiled DSP binary images are provided under dsp/binary/ directory.

The debug configurations will build two separate applications that need to be loaded independently. The ARM application will power and clock the DSP, so it must be loaded prior to loading the DSP application.
