A DVD PROCESSOR WITH DUAL CPUS AND INTEGRATED DIGITAL FRONT-END FOR ADVANCED DVD-BASED CONSUMER APPLIANCES

摘要

We present a single-chip DVD processor. It combines two 32-b RISC cores, a 24-b/32-b audio DSP, video MPEG and subpicture decoders, a graphics and video processor with six video DACs that supports both progressive and interlaced output video, audio, video, and I/O interface units, and several dedicated processing units. In addition, the processor integrates the front-end channel decoder and error correction functions, traditionally part of the DVD loader circuitry. The DVD processor has been implemented using a standard-cell library in 0.18 μm CMOS technology.
