Thumb-2 Technology

ARM and Thumb code each execute in their own processor state. Thumb-2 core technology adds a mixed mode capability, defining a new set of 32-bit instructions that execute alongside traditional 16-bit instructions in Thumb state. This reduces, or can remove, the need for balancing ARM and Thumb code in a system, providing ‘ARM levels of performance’ with ‘Thumb code density’.Thumb-2 technology builds on the success of Thumb technology, adding to ARM’s strengths as the leading supplier of low power, high performance processors and systems, supply cost effective and timely solutions across a wide range of market segments.
