	From: http://www.arm.com/products/processors/technologies/instruction-set-architectures.php

	Thumb-2 technology is the instruction set underlying the ARM Cortex
	architecture which provides enhanced levels of performance, energy
	efficiency, and code density for a wide range of embedded
	applications.

	Thumb-2 technology builds on the success of Thumb, the innovative
	high code density instruction set for ARM microprocessor cores, to
	increase the power of the ARM microprocessor core available to
	developers of low cost, high performance systems.

	The technology is backwards compatible with existing ARM and Thumb
	solutions, while significantly extending the features available to
	the Thumb instructions set. This allows more of the application to
	benefit from the best in class code density of Thumb.

	For performance optimised code Thumb-2 technology uses 31 percent
	less memory to reduce system cost, while providing up to 38 percent
	higher performance than existing high density code, which can be used
	to prolong battery-life or to enrich the product feature set. Thumb-2
	technology is featured in the  processor, and in all ARMv7
	architecture-based processors.
