I am wondering if I can use DSP core in OMAP4430 PandaBoard-ES with code running on Linux OS to speed up some processes? I just want to make some processes inside my code via DSP core and the rest via CPU. Along with my search, I cannot find any good information about it. Is there any tutorial that you can propose? If this process is possible, standard multi-threading techniques is enough to make them run in parallel?
You may try distributed codec engine (sources at github). As an example - github again.
Standard threading model can be used in the following way - one thread on ARM is working while second thread at ARM is waiting for completion of DSP job and in the end it reads data from DSP (for example a blocking process call mentioned here in video decoding api).
