This from an Oct 06 ? ARM pr talking about one of their Cortex processors.

< The Cortex-R4F processor runs the ARMv7 ISA making it fully backwards compatible with existing ARM code that powers billions of systems around the world, and is optimized for the Thumb(R)-2 instruction set. Using the Thumb-2 instruction set, together with the ARM RealView Development Suite, allows on-chip memory sizes to be reduced by up to 30 percent, saving significant cost in the system. In addition it can produce a 40 percent performance improvement over the previous Thumb instruction set running on an ARM946E-S(TM) processor. As memory is an increasingly large proportion of a chip, this provides a significant saving in area and cost to chip
makers using the processor for automotive designs.

Comforting to know that. Thank you ARM. Opty
