I'm working on a design, and am stuck on processor choice.  In one case, 
I can use an ARM with MMU and it'll run Linux - no sweat.  The other 
processor, Blackfin, runs uClinux.  The blackfin runs significantly 
faster (starts at 350MHz goes to 750 I think), and has a migration 
path.  The ARM part max's out at 200MHz, but has some useful 
peripherals.  The blackfin has DSP - which is useful to me.  It's a 
tough choice for me feature wise.  But what about the uClinux vs. linux 
tradeoff? 

I guess my biggest question is how well do multiple programs run 
simultaneously?  I know that there's no memory protection, so there's 
always a risk of crashing another program - or the kernel for that 
matter.  How real, or maybe better to ask what are the odds of this 
happening?  Also am interested in running java, possibly.  Not sure how 
well all this stuff plays together.

sorry for the stream of consciousness - sort of scattered thoughts.
