A scalable single-chip 422PML MPEG-2 video, audio, and system encoder LSI for portable 422PHL system is described. The encoder LSI is implemented using 0.13- mu m embedded DRAM technology. It integrates 3-M logic gates and 64-Mb DRAM in an area of 99-mm super(2). The power consumption is suppressed to 0.7 W by adopting a low-power DRAM core. It performs real-time 422PML video encoding, audio encoding, and system encoding with no external DRAM. Furthermore, the encoder LSI realizes a 422PHL video encoder with multichip configuration, due to its scalable architecture. This results in a PC-card size 422PHL encoder for portable HDTV codec system.
