STn8815 overview

The convergence of computing, multimedia and mobile communications is well underway.

Already the familiar voice phone is being transformed into a personal device with a wide

range of multimedia capabilities. Soon mobile users will be able to benefit from a broad

spectrum of multimedia features and services, to include capturing, sending and receiving

images, videos and music. To deliver such data-heavy, processing-intensive services,

portable handheld systems must be optimized for high performance but low power, space

and cost.

In response to this need, the STn8815 processor platform from STMicroelectronics is a

culmination of breakthroughs in video coding efficiency, inventive algorithms and chip

implementation schemes. It will enable smart phones, wireless PDAs, internet appliances

and car entertainment systems to play back media content, record pictures and video clips,

and perform bidirectional audio-visual communication with other systems in real time.

The STn8815 focuses on the essential features to meet the future needs of mobile products

and services: a high-performance multimedia capability coupled with low power

consumption, and based on an open platform strategy.
