ARM Makes the MOVE on Multimedia Acceleration

ARM has begun licensing its MOVE multimedia acceleration technology. MOVE technology is targeted at MPEG-4 and other video coding schemes for wireless applications. The technology combines memory and power efficient software and hardware components that enable video encoding and decoding at up to twice the speed of existing codecs. This improves the performance and battery life of future video-enabled devices such as smart phones and PDAs.

MOVE technology components, which have been designed to work efficiently with any ARM core-based processor, are comprised of a set of encoders and decoders. In addition, there is an encode acceleration coprocessor.

Implementations of digital audio standards such as MPEG-4 AAC are part of ARM's overall MOVE offering. MOVE with software can enable video to be supported without additional hardware. Alternatively, MOVE hardware acceleration can be incorporated for greater performance, reducing the load on the main processor.

MOVE technology has been tested with multimedia solutions, including PacketVideo. The MOVE technology components feature pre-processing functions such as color conversion and scaling, motion estimation, motion compensation, DCT/iDCT (discrete cosine transform), and bitstream pack/unpack and post-processing filters for deblocking/deringing.

The components can be licensed separately or as a complete package. The technology currently addresses MPEG-4 Simple Profile video. Additional MOVE components will be introduce to target further video and audio functionality in wireless applications. These components are currently under development.
