Abstract
A scalable single-chip 422P@ML MPEG-2 video, audio, and system encoder LSI for portable 422P@HL system is described. The encoder LSI is implemented using 0.13 μm embedded DRAM technology. It integrates 3-M logic gates and 64-Mbit DRAM in an area of 99-mm2. The power consumption is suppressed to 0.7-Watts by adopting a low power DRAM core. It performs real-time 422P@ML video encoding, audio encoding, and system encoding with no external DRAM. Furthermore, the encoder LSI realizes a 422P@HL video encoder with multi-chip configuration, due to its scalable architecture. This results in a PC-card size 422P@HL encoder with lowest power consumption for portable HDTV codec system
