They provide a multimedia experience for an Information Appliance (IA) user that cannot typically be achieved on a PC. By implementing a dedicated coprocessor to perform multimedia tasks, a high quality video viewing experience can be achieved. This high quality is achieved by having a coprocessor architecture that is ideally suited for decoding digital media. In addition, since the decoding is not occurring on the SCx200, system events cannot interrupt the coprocessor’s task of decoding media and thereby causing stuttering of sound or interruptions in the video. Lower power consumption can also be achieved using the SCx200/CS1301 or SCx200/CS1311 solution. The CS1301/CS1311 has an architecture specifically designed for decoding media. The architecture is such that while decoding media, power is not consumed by portions of the system that are not used to decode media. Since the SCx200 is not decoding the media locally, it is able to go into a lower power state. When the CS1301/CS1311 is not decoding media, it uses almost no power. ...
