A dynamic quality-scalable H.264 video encoder chip

This paper proposes a dynamic quality-scalable H.264 video encoder that comprises 470 Kgates and 13.3 Kbytes SRAM using 1P8M 0.13 mum CMOS technology. Exploiting parameterized algorithms for motion estimation and intra prediction, the proposed design can dynamically configure the encoding modes with the design trade-off between power consumption and video quality for various video encoding applications. It achieves real-time H.264 video encoding on CIF, D1, and HD720@30 fps with 7 mW - 25 mW, 27 mW - 162 mW, and 122 mW - 183 mW power dissipation in different quality modes.
