A 99-mm2 0.7-W single-chip MPEG-2 422P@ML video, audio,and system encoder with a 64-Mb embedded DRAM for portable 422P@HLencoder system

摘要

A scalable single-chip 422P@ML MPEG-2 video, audio, and systemnencoder LSI for portable 422P@HL system is described. The encoder LSI isnimplemented using 0.13-Μm embedded DRAM technology. It integrates 3-Mnlogic gates and 64-Mb DRAM in an area of 99-mm2. The powernconsumption is suppressed to 0.7 W by adopting a low-power DRAM core. Itnperforms real-time 422P@ML video encoding, audio encoding, and systemnencoding with no external DRAM. Furthermore, the encoder LSI realizes an422P@HL video encoder with multichip configuration, due to its scalablenarchitecture. This results in a PC-card size 422P@HL encoder fornportable HDTV codec system
