Three-layer cooperative architecture for MPEG-2 video encoder LSI

This paper presents an architecture for a single-chip MPEG-2 video encoder and demonstrates its flexibility and usefulness. The architecture based on three-layer cooperation provides flexible data-transfer that improves the e ncoder from the standpoints of versatility, scalability, and video quality. The LSI was successfully fabricated in the 0.25-mu m four-metal CMOS proce ss. Its small size and its low power consumption make it ideal for a wide r ange of applications, such as DVD recorders, PC-card encoders and HDTV enco ders.
