I don't know exactly how you are defining a "crossover" part.  But if it 
is "a DSP with microcontroller features", then the answer so far is 
"yes".  Both Grant and I have used TMS320F parts - but I would not 
choose to use one again if I could avoid it.  (I can't answer for Grant 
there.)  I have also used a "DSP with microcontroller features" from 
Freescale (from the MC56000 family, IIRC) - though I hadn't mentioned 
that at all.

And if you mean "a microcontroller with DSP features", then as I said 
almost everyone who works with embedded software has used Cortex-M4 
devices.  I have lost count of the number of different ones I have used 
(plus Cortex-M7, ColdFire, and PPC based microcontrollers that had DSP 
features).

So I don't quite see how you could have interpreted the posts as "no".
