After reading about Bare Metal Framework I'm still not sure if it is possible to use DSP and C/C++ Run-Time library included with CCES 2.8.X within this framework. I would like to implement SDR on SHARC Audio Module and I need FFT and reverse FFT plus many other DSP algorithms included in Run-Time library.
Yes, you can use the DSP and C/C++ run-time libraries in the framework. Some of the audio elements and effects use them so you can check out the zip file found here: https://wiki.analog.com/resources/tools-software/sharc-audio-module/baremetal/audio-elements. Also, you will want to keep our FFT accelerator in mind. Here is a post about it that should get you started: https://ez.analog.com/dsp/sharc-processors/adsp-sc5xxadsp-215xx/f/q-a/64126/adsp-sc58x-2158x-fft-accelerator-example-code.
Thank you for your answer. I can now start my new project.
The case is for me successful and ready to close.
