Hi Bob,

Almost! You're describing the Cortex-M3 processor well. However, other
processor cores will appear in the Cortex range which will support ARM
and Thumb instructions. The M3 is designed for deeply embedded
processors; because of the need to keep chip costs down in this market
it only supports Thumb-2, which means the design can be smaller so take
up less area.

There's a short introduction to the Cortex family at
http://www.arm.com/products/CPUs/families/CortexFamily.html

I also hope this helps clear things up!

Cheers,
Tim
