Abstract :
This paper proposes a 1.1 W single-chip MPEG-2 HDTV codec LSI for embedding in consumer-oriented mobile codec systems, and demonstrates its flexibility and usefulness. This architecture consists of a half-duplex 720/30P encoding core, a half-duplex 1080I decoding core, an audio DSP, a RISC, and a multiplexer/de-multiplexer core with a dual-memory scheme for supplying data at high speeds. The LSI, which integrates 3.8 million transistors on a 9.7 mm×9.7 mm die using the 0.13 μm seven-metal CMOS process, implements 720/30P encoding with 1.1 W, 1080I decoding with 0.8 W, and full-duplex 480P encoding and decoding simultaneously with 1.4 W. This LSI will make it possible for consumers to use HDTV quality equipment on a more widespread scale.
