Anyone else wishing Darius2006 would show up?


Anyway, one point of slight confusion above is that Nokia added a DSP to handle audio processing which could be done on-die. The DSP is in fact on-die, and part of the SoC; it comes with the CPU whether you use it or not, so if any gains can be realized by shifting stuff to it, that costs only the software development. Not free, but it doesn't take as much gain to justify it as if it was a separate DSP added in.

Also, I believe the DSP was used on the 770 for video decoding, which is now done in the ARM; that's a rather more powerful justification. So it's not clear (to me) at what point they started planning to add A2DP, but the use of an OMAP with DSP on-chip doesn't actually imply anything about it.
