ARM updates chip architecture with more code density

Chip designer ARM introduced a new instruction set for its ARM architecture that will give consumers longer battery life, better performance and lower memory costs from their mobile devices.

The company's Thumb-2 core technology offers a blend of 16-bit and 32-bit chip instructions which provide both code density for embedded software applications and more efficient use of memory.

By offering higher code density, Thumb-2 will allow ARM's partners to build and support more feature-rich applications for mobile phones, PDAs and other embedded systems, ARM said.

The Thumb-2 technology uses 26% less memory than pure 32-bit code to reduce systems costs and offers 25% better performance than 16-bit code alone, allowing designers to save power by reducing clock speed.

ARM does not manufacture chips itself, but designs chip architectures which are licensed to third party manufacturers including IBM, Motorola and Intel for use in mobile phones and PDAs.

The technology is built on the foundation of ARM's Thumb-2 code compression technology, protecting existing software investments and development efforts.
