Matsushita Electric Ind. Co. Ltd has announced that it has developed a one-chip system LSI for DVD players that implements all analog front-end functions as well as back-end processing functions.

Made with a 0.135m CMOS process technology employing six-layer copper wiring, the company has managed to implement on a single chip the capabilities of an analog front-end IC, a servo and error correction LSI, an A/V decoder, and a system control microprocessor.

In addition to including IP conversion and video noise removal function for high image resolution, the new LSI supports a variety of audio decoding functions, such as DVD Audio, MP3, and WMA.

The development of a single-chip system significantly reduces the overall system cost and the required circuit board mounting area of the company's previous DVD players, which required a minimum of six ICs to be implemented.

The new LSI employs high-precision digital read channel technology based on proprietary PRML technology to achieve stable reading of video and audio data even from scratched or warped DVDs and CDs. It also supports reading of data from recordable media such as DVD-RAM discs.

The IC also uses the Panasonic Media Core Processor software architecture, which is claimed to produce high-quality video reproduction together with support for a range of audio standards.
