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

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-/spl mu/m embedded DRAM technology. It integrates 3-M logic gates and 64-Mb DRAM in an area of 99-mm/sup 2/. The power consumption is suppressed to 0.7 W 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 multichip configuration, due to its scalable architecture. This results in a PC-card size 422P@HL encoder for portable HDTV codec system.
