What is the difference between aDSP and cDSP. I've seen these terms be overloaded quite a bit.
In the Qualcomm DSP user guide it says:
"The processing units include a Kryo CPU, an Adreno 640, and four separate DSPs, each devoted to a specific application space: sensor (sDSP), modem (mDSP), audio (aDSP), and compute (cDSP)."
However, other sources use the acronym aDSP for "application DSP".
When I check through the adsprpc driver which DSP is being used, I only see communication through the Linux file /dev/cdsprpc-smd (although I only see /dev/adsprpc-smd when not running any application)
Is there a definitive source for the differences between these?
