Having been the engineer responsible for determining the performance
difference between OMAP1510's Thumb and ARM modes,  I can
safely tell you that until the advent of Thumb2, there's no way this
is even close to true.  Restrictions on the available operations (and,
later, on the branch predictor in ARM11) stop Thumb from approaching
the sorts of gains you might hope to see.

Sorry :-)
