ARM vs Thumb performance on iPhone 3GS, non floating point code

Question

I was wondering if anyone had any hard numbers on ARM vs Thumb code performance on iPhone 3GS. Specifically for non-floating point (VFP or NEON) code - I\'m aware of the issues

Answer 1

See this PDF from ARM/Thumb for performance/code size/power consumption trade offs.
