ARM NEON Multimedia Instruction Set, To Compete With WMMX?
ARM, the company who has been hugely successful in designing and licensing an instruction set to companies like Intel and Samsung, is now setting its sights on handheld multimedia solutions.
"ARM today launched its new NEON� technology, a media and signal processing solution designed to accelerate a broad range of applications. The ARM� NEON technology is targeted for mobile and consumer products that need the flexibility to implement multiple combinations of video encode/decode, 3-D graphics, speech processing, audio decoding, image processing, and baseband functionality. NEON technology will be implemented in future ARM processors, and will be supported by ARM and third-party tool chains enabling broad industry adoption."
For the architecture folks amongst you, this is another SIMD instruction set -- geared towards mobile devices. It presumably will compete head-on with Intel's WMMX (Wireless MMX). It'll be interesting to see how long these take to hit the market and what effect they'll have -- as it is, battery life is a huge constraint -- but it's cool to see an increased focus on mobile media solutions.

�Intel raised some eyebrows by announcing a new, additional set of instructions for its RISC-based processor architecture, dubbed XScale. The so-called Wireless MMX technology, drawn mainly from Intel's established MMX multimedia extension instructions for PC processors, is intended to enhance multimedia and graphics running on XScale, a processor family geared for mobile devices. The Wireless MMX extensions are expected to let graphics and multimedia routines written for the Intel desktop machines to run on future XScale processors.
David Rogers, marketing manager for Intel, acknowledged that there are some compatibility issues between an XScale processor running MMX instructions and an ARM-based processor from a third party. The XScale processor running MMX �will run all ARM instructions,� he said. �The ARM compatibility is not broken.�
On the other hand, Intel's Wireless MMX technology is proprietary and software written for it will not run on ARM-based chips from third parties, Rogers said. �MMX will not run an ARM chip from Motorola or TI,� he said. � "
