AMD has announced three new discrete media chips to respond to growing demand for advanced multimedia features in mobile phones.

The AMD Imageon 2298, 2294 and 2192 processors, unveiled at the 3GSM World Congress in Barcelona, are designed with a number of media-rich features, including processing of images up to 12Mp, image stabilisation and multichannel audio playback.

AMD will be licensing the technology to other chip manufacturers, including STMicroelectronics, according to AMD marketing director Andy Thompson.

The media processor is separate from the phone's core processor, enabling manufacturers to introduce new multimedia functions more quickly, according to Thompson. The separate architecture also helps reduce power consumption for longer device battery life.

The new media chips will support full DVD resolutions or "five times what was available in earlier generations," said AMD product manager Philippe Decotignie. "Consumers can turn their phones into camcorders and mobile TVs with a very high, very fast resolution," he said.

In addition, the chips will support simultaneous audio and video encoding and decoding, acoustic echo cancellation and video stabilisation. Their TV output function allows viewing of videos and photos on any TV or projector.

Several handset manufacturers are currently testing the new media chips.

AMD has supplied earlier-generation media chips to a number of mobile phone makers, including Motorola and Samsung Electronics.
