ARM has introduced the Thumb-2 core technology, which is an instruction set that provides enhanced levels of performance, energy efficiency, and code density for a wide range of embedded applications.

The core technology is built on the foundation of ARM's Thumb code compression technology, retaining all of the compact code qualities and code compatibility with existing ARM solutions. It is a blended instruction set combining both 16-bit and 32-bit instructions designed to deliver the best balance of density and performance enabling new embedded and mobile devices that support feature-rich applications with longer battery life.

Richard Phelan, Embedded CPU Manager, said, "Thumb-2 core technology uses 26 percent less memory than pure 32-bit code to reduce system cost, and at the same time, Thumb-2 core technology delivers 25 percent better performance than 16-bit code alone enabling designers to save power by reducing clock speeds."
