What is the difference between aDSP and cDSP. I've seen these terms be overloaded quite a bit.

In the 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, such as the HVX presentation and paper use the acronym aDSP for "application DSP".

Also when I look at the adsprpc driver, it looks like the cDSP is a DSP that can be communicated with using a secure channel only.

Is there a definitive source for the differences between these?
