Hi All
It's good to see AVR users aren't one eyed re processors. 

I used 8051's from Cygnal (Silicon Laboratories) a while ago and was 
very surprised. They are nothing like the 8051's of old. They are 
Code compatible with the old ones but they are genuine one clock for 
one operation; not divided by 12 as they used to be. 

They do have a couple of irritating things (like a crossbar register 
that doesn't deliver what you initially expect and register/bit 
differences between the family). But speed wise they are pretty good 
for a low end processor (suggested on the site at 25 >> 100 mips) and 
from playing with them they aren't that far off.

You'll have to follow the links as the final link is too long for 
this post. (General Purpose microcontrollers)
